Hp all in one 7520 printer question?!

[Slynn9092]

Open until about two weeks Ago my HP all in one 7520 printer was working fine. I tried using it today and it saying that the printhead is missing. I’ve tried every possible thing I could think of and that I looked up and it’s just not Resetting. The only difference from a couple weeks ago is the ink has been changed, which isn’t genuine HP cartridges. Could that be the issue? Or is there something else you suggest?  I just wanted to get somebody’s input before I go and spend the money because that is not cheap. I know it’s old but like I said it was printing perfectly no issues a couple weeks ago so I don’t wanna go and buy a new one if I don’t have to. 
Thank you for the help!

Hi @Slynn9092,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It's possible that using non-genuine HP cartridges could be causing the issue with your HP Officejet 7520 printer. Non-genuine cartridges may not be recognized properly by the printer, leading to errors such as "printhead missing." Here are some steps you can take to troubleshoot the issue:

Reinstall Genuine HP Cartridges: If you still have the genuine HP cartridges that were originally installed in the printer, try reinstalling them to see if the error persists. This will help determine if the issue is related to the non-genuine cartridges.

Clean Printhead Contacts: If you suspect that the printhead contacts may be dirty or obstructed, you can try cleaning them. Turn off the printer and unplug it from the power source. Open the printer's access door and locate the printhead. Gently clean the electrical contacts on the printhead with a lint-free cloth lightly dampened with distilled water. Allow the printhead to dry completely before reinstalling it.

Perform a Hard Reset: Sometimes, performing a hard reset can help resolve various printer errors. To perform a hard reset, turn off the printer and disconnect the power cord. Wait for at least 60 seconds, then reconnect the power cord and turn on the printer.

I hope this helps.

Take care and have a good day.
