Bad print quality after running printhead cleaning levels 1 & 2

[KilluaZold]

I just brought my old 8610AIO printer to my jobsite to print needed documents. The software is up to date, the paper is crisp, clean, and flat, the wireless connection is active and strong, I've cleaned the cartridges physically and using the printer, aligned them, and cleaned the printheads with level 1 & 2 cleaning levels yet I still have white lines through the magenta color with no error messages to be found. The printer is out of warranty but I do have Instant Ink.

Should I just get a replacement magenta or is there a different problem? The other ink cartridges work flawlessly.

It's the printhead, don't force too many cleaning cycles in a row, leave the printhead to rest before continuing with cleaning. In a worst case scenario, a new printhead will be needed.

Thank you for the quick reply!

So how long should I wait between running the printhead cleaning again? And if it's the printhead, is that something I'm able to replace by myself or is that a 'professional' thing? If I can do it by myself, do you know off hand how much a new printhead might cost me?

Leave it for a day to rest, the printhead is user replaceable you can find instructions here.

 You can find a new printhead on HP parts store search for CR322A
