HP Officejet 6600 control panel stuck on Ink System Failure.

[gpB_7]

I had this hp printer for years. HP Officejet 6600. I purchased a new print head and that’s when all my problems started. The control panel is stuck on Ink System Failure. Is there a way to reboot the motherboard?

Hi @gpB_7,

Welcome to the HP Support Community. 

I'd like to help!

Have you recently made any changes before the issue started?

This looks like a possible hardware failure with the printer. I would recommend you try these steps here: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector. 

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 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.
