Replacement 8600 Printhead not recognized

[LAJorgensen]

New aftermarket 8600 Printhead will not work. Does HP software cause new non-HP parts to not operate?

Welcome to the HP support community.

I understand that you are getting printhead not detected or missing error on the printer, I am glad to assist you.

Reset the printer

• Resetting the printer might clear the error message.
• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.

Reseat the printhead up to three times

• To clear the error message, you might need to reseat the printhead up to three times.
• Open the door to access to the ink cartridges.
• Wait until the carriage stops moving before you continue.
• Unplug the power cord from the rear of the printer.

• WARNING:
• You must disconnect the power cord before reaching inside the printer.

• Lift the carriage latch, slightly lift the printhead, lower the printhead back into the carriage, wiggle the printhead left and right, and then lower the carriage latch to lock the printhead into place.
• 
• Close the ink cartridge access door.
• Reconnect the power cord to the rear of the printer, and then check the control panel for the error message.
• Sometimes error messages persist after inserting the printhead. If the error message persists, repeat the steps to reseat the printhead up to three times.

My printhead dried up and I could not clean it sufficiently to make it work. So, I bought a new one. That one didn't work. So, I bought a second new one that also doesn't work. ERROR MSG: There is a problem with the printer or ink system. Turn printer off, then on, If problem persists, contact HP.

I have tried, multiple times, every widget, suggested repair procedure, HP Smart, HP Support Assistant and none of them can solve the problem. Since this issue is related strictly to the printheads there shouldn't be any problems with the printer itself. The issue should have been solved with a new printhead. I'm beyond frustrated as I've been trying to solve this problem for atleast two months and I cannot contact HP to get some support. I'll pay for the help/support if that's even available, because I really like this printer.
