Re: Officejet 6600 - "Printer Failure"

Hi tenkros

Make sure the printer is plugged directly into a wall outlet. (don't use a power hub or a surge protector)

Here is a document to clean the printheads. Go to Solution three: Use an automated tool to clean the printhead.

I would update the firmware on the printer.

I have included a link for the firmware update, just select the proper operating system and click next, select firmware. Download and run it.

Let me know if that helps.
