HP OfficeJet 6950 Error Code B8351DA2 at Extended Self Test Diagnostic Page

[HeinrichKarli]

Hello,

hope someone can help me with my problem. I have a printer HP OfficeJet 6950 All-in-One with serial number [Personal Information Removed] and product number P4C78A. My problem is when i print the Extended Self Test Diagnostic Page i get a blank field at the Cyan cartridge where it normally shows the color of the cartridges. I performed a clean printhead routine within the HP Smart software tool and tried to exchange the Cyan print cartridge. But I get wrong colors at my printpages.

At page 2 where it says History Log it shows under 85. Hardware Events and 86. System Events

Error Code: B8351DA2 Time: 2020/12/01

Does someone know what error code B8351DA2 stands for?

@HeinrichKarli, Welcome to the HP Support Community! I’m here to help.

I understand the print quality is not as it should be. Make sure you are using HP ink cartridges.

Perform the steps mentioned in this document - Black or Color Ink Not Printing, Other Print Quality Issues

Clean the printhead up to 2 times and print a test page to check the result.

Try printing from a computer or make color copies from the scanner glass and check.

If the issue persists even after replacing the ink cartridge, I'm afraid this could be a hardware issue with the printhead.

Please reach out to the HP Technical Support team in your region regarding the service/replacement options for your printer. 

You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.
