HP Envy Photo 7855 Black Cartridge 64/303

HP Recommended
Apple MacPro
macOS 10.15 Catalina

I have an error on the HP Envy 7855 printer saying Black Cartridge needs to be removed and reinstalled.

I have done this more than 20 times and continue to get the same error.

I installed new cartridge and still get the same error.

I cleaned the contacts on the cartridge and the print unit with distilled water and lint free cloth. Still same error.

I disconnected the power cord for more than 10 minutes and plugged into printer again. Same error.


I need help. I have the original Black Cartridge and the brand new Black Cartridge and they both give the same error.

What's next.

@Eddieh49, Welcome to the HP Support Community!


I understand you are not able to print in black due to this error. If you have tried the steps mentioned in this document - HP Printer Does not Print and Error Indicates Faulty Ink Cartridge, and the issue persists, I'm afraid this is a hardware issue with the printer.


Please reach out to the HP Technical Support team in your region regarding the service 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.


Note: This printer supports printing in single-cartridge mode. You may continue to print in color by removing the black ink cartridge.


Keep me posted for any other assistance.
