• Turn off the printer and unplug it from the power source.
• Wait 60 seconds, then plug it back in and turn it on.

Check Internal Connections

Well I wont be signing up for paid support for a $500 printer that is 3 years old and we just replaced the original toner cartridge a few months ago. I now have about 4 hours into troubleshooting and the cost of a replacement control panel. I should not have to pay to diagnose a problem. It is hard to explain that to a customer that is paying me to support the printer. They are much more receptive to it being HP's fault and purchasing a Canon printer to replace it. Sure I am out my time and the cost of the control panel but I will keep my customer.  I can use the HP that died for a display unit in my shop next to working printers from other manufactures.
