non-HP chip error message

[cheil67]

I purchased non-HP ink cartridges, and they worked ok. Occasionally I would get a message saying that non-HP cartridges were installed, and HP could not guarantee quality or performance. Using non-HP cartridges, I understand and accept the quality and performance statement.

Just today I replaced the same non-HP brand with another set of non-HP ink cartridges.  Now I am getting a non-HP chip error message, with a statement that says this printer can only accept HP ink cartridges and I am blocked from printing.

It seems unreasonable and unacceptable that printing non-HP cartridges were allowed but now it is not. I have gone back to the cartridge manufacturer but they said this is an HP issue. I'm stuck in the middle...Please help as I need to print.

Hi @cheil67,

Welcome to the HP Support Community

 I'd like to help!

You may refill your cartridges or use remanufactured cartridges, but you may run into problems. HP will not guarantee the functionality of those ink cartridges.

There are many cartridges in the market which is refilled and sometimes the chip is not configured to work with the printer. You need to contact the cartridge manufacturer and find out why its not working. Try a different cartridge supplier and check if that works.

Hope this helps! Keep me posted.

I had no success contacting the cartridge manufacturer so downgraded my printer's firmware and now the cartridges work well. I figured this was the best thing to do since I didn't want to waste the money and have a bunch of cartridges in a landfill. 

I've always liked the quality of HP cartridges, but man they are very expensive! For the printing I do the half price 3rd party brand works well.

How did you downgrade the printer

[cheil67]

This thread here has a lot of helpful information: HP 6978 firmware downgrade? : r/printers (reddit.com) and the step by step process (more or less) is here: HP Officejet Pro 6978 NOT working with 3rd party ink cartridges? Firmware Downgrade to fix this prob.... It took me a couple of tries to get to downgrade but once I did, it recognized 3rd party cartridges and performed well.

Keep in mind you'll need to disable automatic upgrades as this will bring you back to the current version. Also keep in mind this is not something HP supports so I suspect this could invalidate the warranty. 

Good luck!

Appears you Firmware may have been updated automatically, and blocked non-hp ink.   I am returning non-hp ink I bought as while the manufacturer stated it would work they also asked to stop these updates.  Unfortunately HP will not allow us to block these automatic updates.    Yep seems we must use more expensive HP ink.
