HP OEM cartridges no longer working

Sue HP in court!

But for such a change to happen in the first place, you would probably have had to upgrade the printer's firmware. So in the future don't allow firmware upgrades unless you are sure it is safe, or you can return to an older version.

The cartridges you already have can probably not be used currently, but I heard that the manufacturers are also working on a new chip, so future cartridges might work. Besides that HP might be forced to rethink their decision and they might publish a new firmware upgrade to allow other cartridges again.

I have an HP 8610 and on a cents / page basis the cartridges from my local Staples store are a reasonable price. I want my printer to print on demand and not be held hostage to It.

HP has been doing this crap for many ,many years.

I had an HP tape drive that should have been able to use a 3M  DC600XL as backup media.

After a bunch of phone calls it turned out HP had their own version of the tape with a proprietary tape header.

No header,no work.

Oh yeah ,the tapes were twice as expensive.

Tapes and ink cartridges are apples and oranges.

No ,it just goes to show how they market their products.

Ever run into the date code issue with their ink cartridges expiring and not working?

Brand new ,in the box ,but if the date code shows as expired ,the printer will not print.

Only way around it is to take the printer apart ,remove the CMOS battery and reset it to default date.

That is one of the many reasons HP inkjets and various other of their products are on my do not sell list.

Somebody from HP reading this thread is going back to work on Monday and they'll say, "All drivers need a mandatory field update to download the current date into the printer as soon as Windows starts up."

My printer has been set to NOT update for almost a year now, so there is no issue there about auto update.  

I think I read somewhere that maybe a previous version update had a time activation function which has been triggered.  

And yes I have also been subject to the expiry error when my initial cartridges that came with the printer expired.  

This is not healthy for HP from a client perspective.  

How do I revert to a previous version of the firmware?

It's complicated.  For the 8620/8630 series, you might try this.  Note that whenever dealing with firmware, the possibility exists of completely bricking the device into an unrecoverable state.  Attempt at your own risk!

From http://www.ghacks.net/2016/09/18/hp-firmware-update-blocks-non-hp-ink-cartridges:

• - Download and install the HP Web Jetadmin tool from HP website( another bullshit exercise in registering as user to download ).
• This tool allows remote management of HP printers. It allows firmware upgrades
• and can be configured to allow downgrades (see below).
• - Once Jetadmin is installed, run it and have it discover the printers on your network.
• Then you can get the 2014 firmware for HP 8630 by going to the Firmware->Repository->Get Images.
• This will put the older firmware into the repository, but you still can't downgrade yet. Go to next step.
• - On Windows go here:C:\Windows\ServiceProfiles\NetworkService\AppData\Local\HP Inc\HPWebJetadmin\WjaService\config.
• Edit the file FirmwareUpgrade.config.xml
• and change the following to "True"
• HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString.
• True
• HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString
• True
• Save this change
• and now Jetadmin will allow downgrade. So let's do it.
• configure your router to block Wan to printer ip and ensure auto updates, eprint etc are off
• - From Jetadmin, now click the Firmware->Repository->Upgrade Firmware->Device Firmware (next)->(Select the printer)->Select the older firmware
• and under New Version select the old version. Continue one and firmware will be downgraded.
• takes a while to restart the printer after 99% so don't interrupt

Where he says "configure your router to block Wan", unplug the computer's Ethernet cable or the cable modem.

where exactly is the blog you refer to?

From HP blog:
As a remedy for the small number of affected customers, we have issued an optional firmware update that removes the dynamic security feature. To get the update, customers should visit support.hp.com, select their product, select the product support page, and click on the Software and Driver table to download it.

With respect to rindi, I don't consider this a fix.  The problem still exists due to HP's previous mandatory push of the expiry date firmware.  The solution is not being automatically pushed by HP, but must be applied manually by the user.  That is beyond the capability of a significant number of end users.

Request that this be pushed to the RA queue for moderator arbitration.

They asked for the blog site and I gave them the download link for the fix.
We cannot spoon them anymore than that.
My answer pretty much is the fix.
Anything beyond that is speculation.
