Hi,
I am not sure if you have tried manually cleaning the cartridge and the printer copper contacts.
I am providing you a HP web page, to clean the contacts, try the steps and let me know the results.

If the issue persists, try the following link...

This should resolve the issue.
Reply me the result.

I have an HP 812 C printer that displays streaks when printing with color. I have primed it several times then cleaned it several times all according to the mfr's directions. It is a very thrifty printer and I hate to give it up.
Is this a problem I can fix or is it a repair shop issue? A moderate repair charge would pay for itself in about a year in savings on ink! Anyone have any ideas or wisdom about this?
