"The printhead appears to be missing....." Replacing printhead did not fix.

[6StringJazzer1]

I started getting an error "The printhead appears to be missing, not detected, or incorrectly installed." I went through all of the HP troubleshooting steps and the problem did not resolve. Since the printer is out of warranty I disassembled the printhead, cleaned all the contacts, reassembled, and the problem did not resolve. I ordered a replacement printhead (part #CR322A) which included a new set of ink cartridges. Upon installation I got a slightly different error but it still indicated a printhead error. I returned the new printhead and ink cartridges. (This is a very expensive part at $165. There are printers that cost less than for the whole printer.) 

Now I have reinstalled the original printhead and getting the original error.

Hi @6StringJazzer1,

Welcome to the HP Support Community

I understand you are getting an error message " Printhead appears to be missing" on your HP Officejet Pro 8610 E-All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle

You may have noticed that my description said I have gone through all of HP's recommended troubleshooting steps, which you reiterated. In addition I installed a new printhead, which did not work either. I will review your PM.
