Question

Unable to communicate with HP scanning software.

Asked by: TerryNJones

My HP Scanjet 4670 quit working and I replaced it with a Canon 4800F.  Before adding the Canon scanner to my system; I removed the HP scanning software through Add/Remove programs in the control panel.  Now when trying to access the TWAIN version of the Canon scanner I get the message "Unable to communicate with HP scanning software."  I have searched HP's site and can't find a solution.  I'm hoping that you can help.

Thanks in advance,
Terry Jones

first, uninstall your canon and software, then look for "leftovers" from HP and delete those folders

you can look in :
-program files \ HP or scanner folder
-Start>run>msconfig and check in startup for HP startups or in the services for an HP service(click hide MS services first)

I got this response from HP support.  The third step (removing the TWAIN_32 folder)  fixed the problem in my case.


1. Uninstall the Cannon scanner software.
2. Delete Digital folder if it is still there by following the steps given below.

=== Delete the Digital Imaging folder ====

Restart the computer system before following the steps below.

1.  Double-click the My Computer icon.  The My Computer window will
    open.
2.  Double-click the C: drive.  The C: driver will expand.
3.  Double-click the Program Files folder.  The Program Files folder
    will expand.
4.  Double-click the Hewlett-Packard folder.  The Hewlett-Packard
    folder will expand.
5.  Right-click the Digital Imaging folder and select Delete.
6.  Close all open windows.

3. Remove Twain_32 folder from your system.

Remove the Twain_32 folder with the steps listed below:

1.  Click on 'Start' menu and 'Run'.
2.  Type Twain_32 and press enter, a window will open.
3.  Press ctrl+A to sselect all the files including the hidden files.
4.  Delete all the files and empty Recycle Bin.

4. Reinstall the Canon scanning software again.

thanks, but why the C grade? was anything wrong or missing with my answer?

 

by: nobusPosted on 2005-04-09 at 00:31:35ID: 13742793

Thank you for this as it helped me resolve a similar issue for a client.

 

by: nobusPosted on 2010-06-03 at 23:49:22ID: 32914801

tx, another vote for an A grade !

 

by: TerryNJonesPosted on 2010-06-04 at 08:16:53ID: 32917800

Are you really sure that there was enough in your explanation to guide a fix?  I'd have to guess that the explanation from HP was what assisted BGTSLLC.  

Several people on this site seem to try to get in a quick answer even though their answer may not be very helpful.  Being first but overly simple isn't really the way this process should work.

 

by: nobusPosted on 2010-06-04 at 09:28:29ID: 32918486

i never go for a quick answer -  i look at all the questions, and pick those i'm fairly sure i can heklp with.
that's all i do.
if you don't like my answer, i prefer you delete the question, not assign it a C grade...

What did help me was deleting the Twain folder.
