I have an Officejet L Pro 7580 that is set up via router at my home. I have a laptop running Vista Home, every time I return home, and want to either print or scan, the printer is offline. I have right put back online before I can use it. Any ideas guys, much appreciated help needed.

For some reason people seem to have lots of problems with printers when running Vista.

You can find out whether its the printer or the router by connecting the printer directly to the computer and seeing if you have the same problem.

If it is the router:
Try accessing your router by using the default IP address--go to a web browser (Explorer, Firefox, etc) and type in or If you look at the router itself it might show the default IP address on it. They should prompt you to log in to the router's set up. In the set up module look for something like Idle time, and reset it to so that it doesn't go offline like that.

You can also try playing with the printer settings, and uninstalling the driver in Vista and reinstalling.

Good suggestion, but the router settings are the same when I had the XP machine hooked up with the printer. But nevertheless, I will try what you suggest.

Wait a minute.  Let's get our terminology straight, here.  Define, as you're using it, "offline."

I'm really good with this kinda' stuff, and I'll bet I can help you... but I'm completely unclear, at this point, about what's really going on.

Plus, I have that printer... and it's big brother with the color preview screen and the duplex attachment.  So I'm in an even better position to help.

Right out of the gate, neither of those printer have an "online/offline" button or light... like older printers (and, really, now that I think about it, some current-model printers) used to (or still) have.  So, then, what, precisely, do you mean when you say that it's offline when you get home, and that you have to put it online again to make it work?

Do you mean that the printer's off and you have to turn it back on again with the front-panel power button?

Or do you mean that your Vista machine can't "see" it anymore and so when you try to print to it, it fails?

I need some specifics, here.

What, precisely, is going on.  Don't presume it's an online/offline thing.  Take a giant step back and just describe, in layperson's terms, as if I were a three-year-old, exactly, precisely, including verbatim error messages or message dialogs, what's happening.  Begin at the beginning and walk me through it as if I had a learning disability.  Please.

And what router?  (Brand, model)

And is this Vista machine the only machine?  Is the XP machine still in the picture and connected to the router?  Is the printer router-connected, or XP-connected?

Details... please.

Wow I like that. Ok, when I get home and try to print or scan, I am unable to. I have to go in to printers and faxes, right click on the printer, and select use printer online. The XP computer is out of the picture. A little history:
There was an issue with the option for scan to pdf was not showing in the destination list in the solution center, nor the front panel of the printer, even with adobe pro installed (that was never resolved). So I got fed up of monkeying around with HP, and installing and reinstalling the printer, and adobe pro. So I reformatted the computer, and reinstalled the OS. Since then, the offline issue began. You could say I went from having one problem to now having two problems, lol. But I am ok with creating my pdf from the Adobe tool bar. It is the offline issue that is driving me bunkers. So now I have to make sure it is not offline before sending print or scan jobs.

It's 2:23 PM PDT as I write this... and I gotta' go to a client site for about an hour or so.  When I get back, I'll tackle this.

While I'm out, though, please download, BUT DO NOT INSTALL (just download to your "Downloads" folder and then wait for me) the following things:

If you already have some version of the HP L7580 drivers and/or software suite installed, then this:

and this:
or, if your Vista is 64-bit, then this, instead:

Also, please, while I'm gone, download -- and go ahead and install -- these three things:


The free REGSEEKER registry utility:

The free EVERYTHING search tool:

None of them will hurt your machine in any way... and once I get done showing you how to use them (and you see how cool they are for the very specific things I use them for), you'll be glad they're there.  

Also, there's a chance that if you do have UAC enabled, the "Everything" tool may not startup automatically with Windows and you may have to manually allow it to start if it's flagged at startup.  (You could use the scheduler to work around the problem, but we can worry about that later).

Wow, this seems like it might be better performed with some sort of interactive session. I am open to that if you are. I downloaded the items you said for me to download. Sorry it took me so long to get back to you. I have everything saved as you instructed. Thanks a lot for your input. I am curious, looking at everything you had me download, seems this is a fix for more than the printer going offline. Is this for the option of scanning to Adobe Pro not showing in the destination list as well?

Yeah... sorry for the delay.  I have all but stopped very much tech work in my life... except to donate it to worthy non-profits.  These says, I have a ministry of agency and advocacy to the homeless, disabled vets, recent parolees, the elderly and others similarly in need...

...and one of my clients went into the hospital this weekend and I've been dealing with her situation and didn't really get back to you.  I'm sorry.

Gimmee a couple or three hours (it's around noon California time right now) and I'll dig right into this.  Again, sorry.

Okeedokie... I'm finally back.  Sorry it took so long.

Okay.... as for your question about Adobe... no, none of this is specifically intended to fix that... though as part of what happens, that will probably get fixed.

The reason I had you download all that stuff is because HP printers on Vista, just generally, need all the help they can get.  We need to make sure that your printer has the latest, greatest software drivers, utilities, and patches; and that the printer has the latest firmware.  But before that, we need to make sure that all old drivers -- in fact, any references whatsoever to the printer -- are completely off the computer... and I mean REALLY off... hence the need for the three freeware programs I recommended; plus one utility that helps remove any old copies of version 8 of the HP printer software (if it happens to be there).

Then, when it finally comes time to install the printer again, we will not use the "Add a printer..." feature that's built-in to Windows.  Rather, we will let the full suite of printer software made for that printer go out and find the printer, and then configure it however it wants.  Then we update/upgrade the firmware on the printer itself.  Then we update/patch the holy heck out of the printer installation.

If you do all that, then it's very likely that everything will start working properly again.  And even if all doesn't start working properly again, at least then we know, precisely, how everything's been installed and we have a well-known and proper launching pad from which to begin whatever troublehooting might ultimately be required.

It's sort of like not really trying to troubleshoot a Windows problem until/unless you're absolutely certain that Windows, itself, is completely up-to-date with all known security and other patches.  That's sort of what we're going to be doing, here.... just making sure that your printer installation on Vista is as HP envisioned it... textbook.... unassailable.  Usually, that, alone, fixes all ills.  And, again, even if it doesn't, it's the right place to be when troubleshooting begins.

So, I'm making this posting to tell you that I'm back, and that while you're reading this (if you get to reading this posting right away), I"ll be typing.  (Or, if it takes you a little while to get back here, then all instructions will, by then, likely be here).

Stay tuned...

Oh, yeah... one more thing, regarding the Adobe thing...

You wrote:  "There was an issue with the option for scan to pdf was not showing in the destination list in the solution center, nor the front panel of the printer, even with adobe pro installed (that was never resolved). So I got fed up of monkeying around with HP, and installing and reinstalling the printer, and adobe pro."

Scanning to PDF is best done from within Adobe Acrobat Professional... and that's been true since way back in version 3 or something like that.  With Acrobat 8 Pro (which is what I have), one would launch Acrobat and get to its main screen; then click on either the "Create a PDF" button (if it's present), or click on the "File" pulldown menu, and then, in either case, select "From Scanner."  

A scanner dialog (not HP's, but Adobe's) pops-up.  As long as the scanning device (and it should show "OfficeJet Pro L7500 TWAIN") in the uppermost drop-down selector box is properly selected, you can probably go with the defaults for everything else in that dialog (though, it's kinda' fun to experiment with them whenever you find the time), as long as "New PDF Document" is selected.

Then you just click on the "Scan" button, then give what you're about to scan a filename, and then "yes" or "okay" to the dialog telling you to put what you want to scan facedown on the glass; and then the HP scanner utility will pop-up and it will do an initial, proofing scan.  All the adjustments that you might want to make before the final scan should be self-evident.

When it's finally the way you want it and you want to make the final scan, click on the "Accept" button and it will either do a final scan (if you changed anything), or it will just process the one it already did, and then pop-up a dialog asking you to specify if the scaning is complete, or if there's another page to be scanned as part of the scan-to-PDF file that you're creating.

If it's a one-pager, then you just select "Scanning Complete" and click on the "Okay" button; or if there are more pages, then select "Scan More Pages (Put sheet 2)" and then click on "Okay".

Assuming it's a one-pager, after selecting "Scanning Complete" and clicking on "Okay," whatever you scanned should show-up in the document area of Acrobat... and all you'd have to do beyond that is make sure to save it after you've done whatever you do (if anything to it).

Voila!  That's how to scan-to-PDF.

Generally speaking, using the L7580 from the HP Solution Center is probably not the best idea.  As long as the L7580 is properly installed, all software on the system can "see" it as a printer; and all software on the system which is capable of acquiring something from a scanner can also see it as a "scanner."  And all software should also be able to print to its "fax" driver.  So, when you stop and think about it, there's almost no reason to ever launch the HP Solution Center except in the beginning, whenever you want to initially configure the L7580.  After that, quite frankly, I never use the Solution Center... but that's just me.

Plus... and what I'm about to tell you is a terrific reason to just get that stupid HP Solution Center out of your system tray in any case...

...in a LAN configuration, that darned little Solution Center icon in the system tray involves the running of a Windows process that doesn't behave well in Vista.  It polls the LAN to verify the presence of the printer every roughly one second, or thereabouts.  And it seems to use-up a little RAM every so-many polls.  Next thing you know, RAM's all goofed-up with not properly-released crap left behind by this process...

...and if you let it run like that long enough, one of the symptoms can be that audio starts starts to become "stuttered" because the darned HP system tray icon and the server-related process behind it has gummed-up everything.  Only a system restart will get things back to normal...

...and even then, if you let it run long enough, it all happens again.

Personally, I went into Vista and told it to disable (but not delete from its list of startup programs and processes) anything and everything related to the L7580.  Believe me, as long as the L7580 is installed properly, and the FULL SUITE of its software is present (and was also installed properly), that little system tray icon (and its ability to launch the Solution Center) isn't really necessary.

Whenever/if-ever you actually DO need the Solution Center, just launch it from its normal program icon... which you can even have right on your desktop or in the QuickLaunch tray if you want it really handy.  In fact, that latter method is what I did.  Instead of its icon being in the System Tray on the right, constantly running, and mucking-up everything, I put it into the Quick Launch area on the left... where it's just as accessible... but it doesn't run all the time in the background.

But that's just me.

Anyway... now on to my writing about what this thread's really about...

Stay tuned... be back soon.

Okay, then...

...the first step is to delete the L7580 printer (and fax, if it's present)... but not in the way you might have guessed... not by removing it (at least initially) from Windows's list of available printers.

Turn off the L7580 with the power button on its front panel.  If it's a wired LAN, unplug the Ethernet cable from the back of the printer (if it's wireless, don't worry too much about the printer's connection to the LAN).  Then also unplug the printer's 120VAC connection from the wall outlet.

Log-in to your router's control panel and do a DHCP release and renew (which may break your connection to the router's control panel, so you may have to re-key its IP address into your browser and re-login to the router's control panel).  Look at the router's list of connected computers (or "LAN-connected devices" or whatever your router calls its list of computers and printers connected to it; and wherever it is in the router's control panel's various pages).  Verify that the L7580 is no longer on the list of connected devices; and that no IP address is assigned to it and maybe waiting for it to reconnect.  Only your computer should be shown (along with any other computers or OTHER printers connected to the router... just not the L7580 (which, when it was connected, probably had a network name that's kinda' cryptic... like "HP287DA0" or something wacky like that).  Logout of the router (or close the browser window... whatever).

Launch the REVO UNINSTALLER.  It will take a moment to list everything you have installed on the computer.  Before actually using REVO, left-single-click on REVO's "Options" button and then on the "General" item (on the left), and then make sure that "Advanced Mode" (on the right) is checked.  Then left-single-click on the "Uninstaller" (item on the left), and then make sure that only the "Only run the built-in uninstaller (on the right) is left UN-checked (e.g., all other items on the right except "Only run the built-in uninstaller" should be checked).  Then left-single-click on the "Okay" button at the bottom to get completely out of REVO's "Options" area.  It may re-scan for all installed programs... if so, that's fine.

Make sure that REVO is sorting on the "Application" column (and that said column's little arrow thingy is pointing upward, forcing it to sort from digits and A to Z, ascending, starting at the top of the column).

Scroll down in REVO's "Application" column to the applications beginning with the letter "H," and then find the "HP OfficeJet Pro All-in-One Series" item.  Left-single-click on that item to highlight it; then left-single-click on REVO's "Uninstall" button up at the top.  You will be asked if you really want to uninstall, specify "yes."  The "Select Uninstall Mode" dialog will pop-up.

Choose the fourth (bottommost) of the four choices... the "Advanced" mode.  Then left-single-click on the "Next" button.  You will be taken to the "Performing the initial analysis and uninstall" dialog, where a restore point will be created, then the application's data will be analyzed, then the application's own uninstaller will be launched.  There may be weird delays... including that the REVO dialog may get all the way through the fourth step (the one labeled "After the application's uninstaller has finished...") before the HP's own native uninstaller even finishes... or sometimes before it even launches.  So, be careful... don't get ahead of yourself.  Don't left-single-click on REVO's "Next" button before the HP uninstaller does its thing.

When the HP native uninstaller finally launches, just left-single-click, first, on the "Continue" button.  The uninstall will begin... notice the progress bars.  Just be patient.  You'll occasionally notice things being removed from the REVO installed applications list, and REVO repainting the listing behind the HP uninstaller window... just ignore all that and keep being patient.  

Finally, you'll get (from the HP uninstaller) the "Cleanup Complete" message, and the "OK" button at the bottom will be clickable.  Left-single-click on the "OK" button.  The HP uninstaller will close.  Now REVO will do its additional work (the single biggest thing that makes REVO so cool)...

...go ahead and left-single-click on REVO's "Next" button.  REVO will start scanning for anything which the HP uninstaller may have left behind.  It will search for two things:  Leftover files and/or folders, and leftover registry entries (though not in that order).  Since you chose the "Advanced" REVO mode, it will take some time.   When the progress bar gets about 60% of the way over to the right, it may even seem for a while like it just stalled there.  IT HAS NOT!  Just be patient.  Let it run.  Go get coffee or something.

Finally, when the progress bar gets all the way over to to the right, and the "Next" button is clickable, it will be done.  Left-single-click on the "Next" button.  You'll taken to the "Found leftover registry items" dialog.  And it may even still be finding them as you reach that dialog (indicated by everything still being kinda' grayed-out.  Just be patient until everything's nice and black-and-white, and the "Next" button is clickable.  

Occasionally (very, very rarely) REVO wants to delete too much; so it sometimes pays to scroll through what it says should be deleted and verify that it really does.  Fortunately, REVO does a really good job with HP stuff... so you may rest assured that all roughly 4,253 (give or take) things which REVO says it found need to be deleted.  And FEAR NOT... only those things which are BOLD will actually be deleted, even if unbolded things higher-up are also checked.  So there is no harm in just putting a checkmark next to "My Computer" (or left-single-clicking on the "Select All" button... which, actually, is probably the better way to do it) so that you can check all four thousand two hundred and however many registry items REVO found which need to be removed.  Again, ONLY THE STUFF THAT's BOLDED WILL ACTUALLY BE REMOVED.  Then, having selected all, just left-single-click on the "Delete" button.  You'll be asked if you're sure you want to delete all of the selected registry items, which you are, so left-single-click on "Yes."  The deletion will happen in a snap.

Then click on the "Next" button.  You will be taken to the "found levtover files and folders" dialog.  Once again, left-single-click on the "Select All" button... then on the "Delete" button... then confirm that "Yes" you do want to delete to the Recycle Bin.  You may be told that some things can't/won't be deleted until a reboot (because they're locked because they're in use); left-single-click on "OK" to indicate that that's fine... and the probably four or so things that couldn't be deleted will remain.  Just left-single-click on the "Next" button, and you'll be taken to REVO's "Finished" dialog.  Just left-single-click on the "Finish" button.

Close REVO, then REBOOT... best by shutting all the way down, waiting a second or two, then turning the machine back on... but if you just restart Windows, that would probably be fine, too.   Wait for Windows to fully and completely restart... wait for the system tray to fully populate, wait for the mouse pointer to stap going back and forth between an arrow and an hourglass, and wait for hard drive activity to pretty much settle down.  Be patient.

Launch the REVO UNINSTALLER again, and let it finish finding however many installed programs you have.  Then left-single-click on the "Company" column heading, making sure that the little arrow therein is pointing upward (if it's pointing downward, then click on it again to toggle it upward).

Scroll down the "Company" column until you find all "Hewlett Packard" and "HP" items.  The following things may or may not be present:

     32 Bit HP CIO Components Installer
     HP Print Diagnostic Utility
     HP Product Assistant
     HP Update
     HPProduct Assistant
     HP Imaging Device Functions 8.0
     HP OCR Software 8.0
     HP Photosmart Essential
     HP Solutions Center 8.0
and there may or may not be others... all of which need to be uninstalled using REVO's "Advanced" method, just like you just did the main L7580 printer and fax apps.  You may have other "Hewlett-Packard" or "HP" or "Hewlett-Packard Company" items listed, but the problem with uninstalling those (if they're not on the list, above), is that if you happen to have any other HP devices connected to the computer, or if your computer is made by HP, you could end-up over-uninstalling (if that's even a word).  All stuff on the list, above, is positively L7580-related; and even though such as the "HP Update" and "HP Product Assistant" and a couple other things are also present on HP-brand computers which have no HP-brand printers attached to them (and so should probably not be deleted), when we re-install the full software suite for the L7580, all that stuff will be re-installed, too... so don't hesitate to delete all of the above list.  Start with the items with "HP" in the "Company" column... preferably the "HP Photosmart Essential", then the others.  Then all the rest, one by one, using REVO in the same way that you just did... rebooting where told to, and not rebooting for all the rest.  Just plow through it.  It may take a little time.  And uninstalling one thing may remove one or two others, so even though it looks like you'll have to do a dozen and a half or so separate uninstallations, it might end-up being less.  Just get some coffee and settle in for a marathon uninstallation session.  Enjoy!  See 'ya in a week! [just kidding]

     IMPORTANT NOTE:  Remember to be patient whenever REVO's trying to launch the
     HP native uninstaller.  REVO may finish all four of its stes before the HP uninstaller
     even launches.  Or the HP uninstaller may be damaged or not properly present and
     may not even launch, or may fail/abort.  Occasionally, it will even time-out (literally
     just sit there acting like it's going to launch and you could run to McDonalds and come
     back and it'll still be ditting there doing that).  If so, don't hesitate to just close or cancel
     or otherwise abort-by-whatever means the HP native installer and just let REVO
     handle it all.  BUT DON'T BE TOO QUICK TO DO THAT.  Make triple-net certain that the
     native HP uninstaller for any given component is really and truly just not going to work.  
     I've seen the uninstaller, on a 2.2GHz machine with 4GB of RAM (so a fairly peppy
     machine, overall) take quite a few minutes to finally get done collecting itself and finally
     up and start doing something.  So, BE PATIENT.  Give the native HP uninstaller every
     chance to do its thing.  Most of it time, it will.  But on the rare occasions when it just
     dies or stalls or errs or by some other means simply craps out (or times out), then
     don't hesitate to cancel it (even if you have to use Task Manager to forcibly do it).  
     REVO can probably still get it uninstalled, for the most part, all by itself.  The bottom
     line is, whenever REVO's on its "Performing the initial analysis and uninstall" screen,
     don't be too quick to click on REVO's "Next" button.  Give the native uninstaller every
     chance to work; and only move on without it having done so if you simply have no
     other choice... which, with any luck, should be either not at all or at least darned rarely.

When every last bit of it is uninstalled, you'll be ready to manually circle back around behind REVO and remove anything that even it may have left behind using the three other freeware tools I had you install...

...but since this all, up to this point, could all take a while, and just in case you're sitting around waiting for me, I'll go ahead and post this much, and then keep typing while you're doing at least what I've instructed down to here.  Hopefully, by the time you finish, I'll have posted the next part (and if not, then please just be patient... I won't stop 'til this is all done in this session)...

Something I should have added about REVO...

...whenever (if ever) it can't find registry items to delete, then it just moves on, without mentioning anything about it, to files/folders that may need to be deleted; and if it finds none of those, either, then it just jumps straight to the notice that it's pretty much done and that all you have to do is left-single-click on the "Finish" button.  If any of that happens for any of the HP components, fear not.  Nothing's gone wrong.  Just go with whatever REVO does... again, REVO's really well-behaved with well-designed and responsible installers and uninstallers... and HP's generally are.

Also, while you're waiting...

...if you don't already have the free "CCleaner" installed on your machine, then by all means download and install it.


We'll be using it, too.

Oh, but there's more...

Continuing now...

The "HP Print Diagnostic Utility" (if you even have/had it), and the "32 Bit HP CIO Components Installer" (if you even have/had it) might (or might not) seem to remain behind, even after you've more-than-once tried to uninstall them.  They're stubborn.  And the problem with them is that once you've tried to uninstall them using REVO, even if they remain on REVO's list of installed programs, they'll be damaged... part of them missing.  So, if they're still there after REVO has attempted to uninstall them, it's just easiest to forcibly remove them from the list of installed programs.  Whatever part of them remain will be scrubbed in a later procedure.  

One easy tool for forcibly removing anything from the list of installed programs is CCLEANER.  We'll be using CCLEANER for other stuff, too... but for now...

...launch CCLEANER...

...then click on CCLEANER's "Tools" button on the left; then click on the "Publisher" column heading (to sort by Publisher); then scroll down to "Hewlett-Packard" in the "Publisher" column.  If either "HP Print Diagnostic Utility" or "32 Bit HP CIO Components Installer" is there, left-single-click on them to highlight them, and then left-single-click on the "Delete Entry" button to forcibly remove them from Windows's list of installed items.  If you get any kind of error telling you that it can't actually be done, don't worry about it.  Of all the HP utilities that could be left behind, those two are the least objectionable... and we're going to be re-installing them in any case.

Then click on CCleaner's "Startup" button on the left; then click on the "Program" colum heading to sort by program; then scroll down 'til you find the HP printer tray application and the updater (those should be the only two) in the list of startup programs.  Left-single-click on them to highlight them, then click on the "Delete" button at the bottom to delete them from the startup list.

Then close CCleaner.

Then... REBOOT.  (People, I tell you, don't reboot enough during this sort of work!)

Once you're back up again (and everything has fully calmed down), you're ready for the obvious:

     Making sure that the L7580 printer and fax are both
     gone from Windows's own list of available printers; and
     also making sure that related drivers and ports are gone.  

Open Windows's "Control Panel," then left-single-click on "Printers" to open Windows Explorer's "Printers" window.  On the right-hand side, whatever printers are there (and if you have Adobe Acrobat Professional, then Acrobat's printer driver should, at the very least, be there; and if you have Microsoft Office then at least a couple of its printer drivers should also be there) should NOT include the L7580 (or the "HP OfficeJet Pro L7500 Series" or anything like that).  If it's there, then something's probably wrong... but we'll conquer it, in any case.  If they're there, then manually delete them.  Period.  If they're not there (or if they were and you deleted them), then...

...left-single-click on the "File" pulldown menu of Windows Explorer's "Printers" window, then select the "Server Properties..." and the "Print Server Properties" multi-tabbed panel should open.

Left-single-click on the "Drivers" tab.  Nothing even remotely related to the L7580 (or the HP Officjet Pro L7500 Series") should be listed there.  If anything is, left-single-click on it to highlight it, and then left-single-click on the "Remove" button to remove it.  If anything objects or can't be removed, don't sweat it... whatever we do in the registry should find and remove it.

Then left-single-click on the "Ports" tab.  Scroll down until you find the "Standard TCP/IP Port" that the HP L7580 was using (there should probably only be one, but if you evern fiddled with ports for that printer, there may be more).  If your router assigns ports in the IP range beginning with "192.xxx.xxx.xxx", then the "Port" column should show "HP_192..." for any L7580 ports which might be present.  However many like that there are, left-single-click on them to highlight them, and then left-single-click on the "Delete Port" button to remove them.  Because no HP software related to the printer should be running by this point, and because the printer is off, and the router isn't giving it an IP address anymore, the port should delete without any error messages.  However, if it doesn't, again, don't sweat it since what we do in the registry should find it and remove it.  (Still, if it doesn't delete, that would be odd... and may be an indication that more problems are yet to come... but let's keep going.)

Then, believe it or not... yes... REBOOT... again.  [oy!]

When you're all back up and running again, you're finally ready to begin poking around a little and verifying that REVO didn't leave anything behind.  Since REVO's biggest thing in life is making sure that installers don't leave anything behind, it's weird, I know, to contemplate that REVO itself may have... but it sometimes (rarely, mind you) does...

...so, what the heck... launch the "Everything" search tool.  If it needs to scan the whole hard drive first, then let it.  It only does that the first time you use it.  Right up near the top, just below the "File" and "Edit" etc. pulldown menus, is EVERYTHING's search box.  Type "HP" and you won't have to press any keys on the keyboard or antyhing.  In an instant, it will find everything (and I mean everything... files or folders) that has(have) the text string "HP" in it(them)... no matter where said text string is.  So, therefore, BE CAREFUL... because as you can see, non-HP stuff gets found, too.  Just work slowly and carefully.  You should be able to scroll down and find really-and-truly HP stuff... like, for example, an "HP" folder in the "Program Files" and "Program Data" folders... as well as "HP" folders down in the


folders.  Those are probably the only folders that you should really delete using EVERYTHING.  You'll find all kinds of other stuff... in the recycle bin, or in the "driver store" areas, or in the "winxsx" areas, or in "restore" areas, or in various kinds of temp folders, or in folders related to Adobe or Office... but, honestly, none of those really matter.  You're really only, at this point, trying to remove the folders really obviously related to the OfficeJet L7580 printer... and those should be self-evident.  Stick with those, and don't dig too much more deeply into Windows to hunt-down anything HP printer related (because, after all, Windows comes with certain HP printer drivers built-in... and you wouldn't want to accidentally delete those).  Just delete the obviously Officejet Pro-related files/folders, the "L7500 Series" kinda' stuff... and no more.

Then close EVERYTHING.

Then launch REGSEEKER.  Click on "Find in registry..." on the left.  On the right, make sure everything is checked except "Search Files" and "Match whole word."  Everything else should be checked.  And make sure that "Backup before deletion" is checked down near the bottom left.

In the "Search for:" field, type "OfficeJet" (without the quotes), then left-single-click on the "Search" button.  Go get more coffee while it runs.

Maybe a doze or two entries will be found.  Selecting multiple things here is like selecting multiple files in Windows Explorer.  It'll be faster to select them all, then unselect any that you don't want to delete... so, then, left-single-click on the topmost item, then scroll all the way down and then hold down the keyboard's  [Shift]  key while you left-single-click on the bottommost item, then release the keyboard's  [Shift]  key.  All however many items there are should be highlighted.

Now, scroll back up and begin with the first one... and just make sure that none of the items selected has anything to do with other non-HP programs... things like Microsoft Office, or anything Adobe, or anything related to the Gadwin PrintScreen utility (if you even have it)... stuff like that.  If there are any of those entries, then, one-by-one, de-select them by holding down the keyboard's  [Ctrl]  key while left-single-clicking on the (again, one by one) and then release the  [Ctrl]  key.  Only those items which you clicked on that way should be de-selected, leaving everything else selected.

Scroll-up/down and just visually verify that everything else that's still selected is really obviously related to the HP Officejet Pro L7580 or L7500 series printer.  It should be really obvious... and the word "officejet" will (because it was the search term) be in blue letters, so it should stand out.  

Even if you delete something you shouldn't have, a backup of the stuff to be deleted willl be made just before deletion so that it could be reinstalled back into the registry if it turns out, later, that it shouldn't have been removed.  So fear not... or at least not too much.  The key, here, is to just make sure that everything selected for deletion is really Officejet printer related, and isn't some kind of officejet printer component which Adobe or Microsoft Office or some other app installed for itself.

So, bottom line, that probably means that pretty much everything found in the REGSEEKER search should be selected.  Once you're certain that it all is, then press the keyboard's  [Delete]  key to delete them from the registry.  You'll be asked to veryify... say "Yes" and then you'll be told what the name of the backup will be, say "OK" and they'll all be deleted in a snap.

Next, search the registry in REGSEEKER for anything with the text string "HP Solution" in it (again, without the quotes).  Only one or two things should be found; and if they're just obviously related to the "HP Solution Center" software, delete them, too.

Next, search the registry in REGSEEKER for anything with the text string "Photosmart" in it (again, without the quotes).  Only maybe a half dozen (give or take) things should be found; and  if they're just obviously related to the "HP Photosmart Essential" software, delete them, too.

Next, it probably wouldn't hurt to do one final REGSEEKER search for the string "L7580" (again, without the quotes).  I doubt if anything will come up, but it couldn't hurt to search.  And, if found, then, again, verify that it's really and truly Officejet printer related, and not obviously in the folder of any other non-HP app, and then delete it, too.

No doubt there are still tons of HP-printer related things in the registry, but since some of those came with Windows, and pretty much none of the others will hurt us for our purposes here, just don't worry about 'em.


Find the file which I earlier had you download named...


...and left-double-click on it.  It will launch a command (DOS-style) command prompt window, and a Windows Explorer window, putting you into a temp folder which has a name beginning with "7z...".  

     NOTE:  You're about to run five (5) batch files, in a par-
     ticular order.  Theoretically, one should only have had to
     have run the (fifth) Level 4 batch file... but I'll be
     darned if it doesn't scrub better, overall, if you run
     all five, in the order instructed above.   Go figure.

All five batch files will behave roughly the same, to wit:

First a DOS-style command prompt window will open, and you may be instructed therein to make sure the printer's running and attached... just ignore those insturctions.  But then you'll also be told to press the keyboard's  [Enter]  key to continue... definitely do that.  There will be a flurry of activity involving one or more installer/uninstaller windows opening and running progress bars from left to right.  Just let them run.  Most will just close, but if any of them end with a notice that Windows must be restarted, just put a checkbox next to that you will restart later, and then just left-single-click on said notice's "Finish" button.  If any DOS-style command prompt windows remain open, just press any key to close them (or, if that doesn't work, click on the little "X" button in the upper-leftmost corner of the window.  Then run the next batch file.  That's how to handle them all.  Don't worry about restarting Windows... we'll handle that momentarily.  So, then, let's begin...

In the right pane, find the  UNINSTALL.BAT  file and left-double-click on it to run it.  There'll be a flurry of activity and then it will be done.  Close any DOS-style command prompt windows which may still be open.

Find the  UNINSTALL_L1.BAT  file and left-double-click on it to run it.  In the DOS-style "command prompt" window, press the keyboard's  [Enter]  key to continue.  There will be a flurry of activity which may end in an uninstaller window asking you to restart Windows... but with a box allowing you to do it later... CHECK THAT BOX... then left-single-click on the "Finish" button.  If any DOS-style command prompt windows remain open, close them.

Then find the  UNINSTALL_L2.BAT  file and left-double-click on it to run it.  A DOS-style command prompt window will launch, and you will be asked to press the keyboard's  [Enter]  key to continue... do so.  After a flurry of activity from an uninstaller dialog (there may be more than one), it will come back to that DOS-style window... press any key to close it.

Then find the  UNINSTALL_L3.BAT  file and left-double-click on it to run it.  A DOS-style command prompt window will launch, and you will be asked to press the keyboard's  [Enter]  key to continue... do so.  After a flurry of activity from an uninstaller dialog (or two... or more)... and you'll finally be presented with an uninstaller dialog telling you that you must restart Windows... but with a box allowing you to do it later... check that box... then left-single-click on the "Finish" button.  If any DOS-style command prompt windows remain open, close them.

Then find the  UNINSTALL_L4.BAT  file and left-double-click on it to run it.  A DOS-style command prompt window will launch, and you will be asked to press the keyboard's  [Enter]  key to continue... do so.  After a flurry of activity from an uninstaller dialog (or two... or more), it will come back to that DOS-style window... press any key to close it.

Then REBOOT. [whew!]

When it's all back up and running again...

...launch CCLEANER again.  (Ohgod... when will this end!?) [grin]

Left-single-click on the "Options" button on the left, then the "Advanced" button.  Make sure that the item "Only delete files in Windows Temp folders older than 48 hours" is UNCHECKED.  

Left-single-click on the "Cleaner" button on the left.  Go to the "Windows" tab.  Get out a piece of paper (or take a screenshot or something) and make note of what's checked and what's unchecked.  Then uncheck everything except "Temporary Files" and "Start Menu Shortcuts" and "Desktop Shortcuts."  Make sure that those three are all checked.  

Then, go look at what's checked on the "Applications" tab.  It doesn't much matter what's checked there... except that you may want to uncheck "Saved Form Information."  You can safely leave everything else checked.  Then left-single-click on the "Analyze" button and let it work.  When it's at 100% at the top, and you're given the list of what will be removed, left-single-click on the "Run Cleaner" button near the bottom.  Click on "OK" to proceed... and let it run.

Then look back at your notes (or your screenshot) and put checkmarks back next to whatever was checked on CCLEANER's "Windows" tab.  You can leave everything as it is on the "Applications" tab.

Then left-single-click on the "Options" button on CCLEANER's left; then the "Advanced" button; then put the checkmark back next to "Only delete files in Windows Temp folders older than 48 hours."  

Then left-single-click on CCLEANER's "Registry" button on the left; then make sure that pretty much everthing is checked (that is, unless you feel strongly about anything that shouldn't be).  For example, if you've got your start menu in a certain order, then perhaps unchecking "Start Menu Ordering" wouldn't hurt.  But everything else should probably be checked.  Then, left-single-click on the "Scan for Issues" button near the bottom and let it run.  When it's finished scanning (the bar across the top will be at 100%), left-single-click on the "Fix selected issues..." button down near the bottom.  Specify to fix all selected issues, and say "OK" to that you're sure.  It should do it pretty much instantly... then close any dialogs left open.

Then, believe it or not, do it again... left-single-click on "Scan for Issues" and let it work.  Then, when it's done scanning, tell it to "Fix selected issues" and then "Fix All Selected Issues" and then "OK" to that you're sure... then let it work, again.  Then close any left-open dialogs.

Then, believe it or not, do it one more time... exactly as in the immediately preceding paragraph... and then again, and again... until it finally doesn't find anything to fix anymore.  (It should probably only need to do it maybe twice or three times at most... but do it however many it takes until CCLEANER finds nothing more to fix in the registry.

Then close CCLEANER.

Then REBOOT... yes, you read it right (people never reboot enough when they're doing this sort of thing).

While the computer's starting back up, bask in the glory of knowing that you've removed the OfficeJet and its software and drivers from your Vista machine like has almost never been done before by anyone... er... well... except maybe by the extremely anally-retentive, such as myself. [grin]

At this point, if all worked, above, your Vista machine should be as scrubbed-free of anything having anything to do with the HP OfficeJet Pro L7580 printer as you would ever need it to be.  Oh, of course, there's still stuff left hidden down in the nooks and crannies.  But for our purposes, it's as scrubbed of L7580-related stuff as we need it to be.

So, then... that leaves us to move on to the next part:  Reinstalling the printer...

...which I will cover in the next posting...

Oh... something I forgot... so sorry...


Left-single-click on "Find in registry..."

Make sure that ALL checkboxes except "Search Files" and "Match whole word" are checked.

Make sure that "Backup before deletion" (near the bottom) is checked.

In the "Search for:" field, type    32 Bit HP CIO Components Installer     and then press the keyboard's   [Enter]   key.

Wait 'til the search is done, of course.  It may find a few entries... maybe six or something like that.  If it find any, delete them all.

Then close REGSEEKER.

Then wait for the next posting...

Hey I am really thankful for your assistance. I haven't had a chance to apply your solution as yet. I am waiting on the person with the issue to allow me to work on it. Please continue to supply the necessary instructions. I will just have to take my time and go thru the list of thing once I get the opportunity. Once you are thru, I will print the entire thread.

I still have a couple postings to go.  Hold-off on any of it 'til you read all of it...

...in part because I may offer-up at least one alternative method at the very end.

It's Saturday as I write this... I'm hoping to be able to find time to keep working on it today.

I never got a chance to resolve the issue; the user got rid of the printer and got a new one. So much effort was put into post towards a complete solution, that to not award points would be unjust. Thanks for all the input.
