Try holding down the ok -- cancel -- black -- color buttons with 4 fingers while at the same time powering the unit off. Keep them held down till it is off. Then turn it back on normally & it should try to do "Maintenance" & you hear a whirling noise --- that is the ink pump spinning to try & pump in ink to the print head.
Here are the details. Got the Ink System Failure message. The error code shows was '0xc18a0005'. The tech had me press and hold the '*' key on the key pad, then press the '#' key and release them both. Then he had me enter '123' to enter maintenance mode. He then had me press the right arrow (beside the OK button) until System Config. menu appeared on panel. Then pressed OK two times to clear the error condition, then cancel two or three times to return to the top menu. Then powered off and back on, printed a test page just fine, copied a document fine.

Hi,
Is this printer connected on a Mac System or a Windows PC?

Try this:
Hold the OK-Cancel-Black-Color keys to have the system go through an extended diagnostic. Then Install the latest drivers from HP website
