Product: HP OfficeJET pRO 6978
Operating System: Microsoft Windows 7 (64-bit)

I initally received error message Ox6100004a indicating a paper jam.  However, there was no such issue.  After following forum advice to clean the paper feeder rollers, I received another error message indicating a printhead error.  My machine was shy of 2 years old having only printed approximately 50-100 pages per year, so reading on the forum that it needed to be replaced seemed unreasonable.

 

Though out of warranty, I called HP support and was instructed to:

1)unplug both ends of the power cord from both the printer and my surge protector

2)hold the power button for 5 seconds

3)plug in the printer directly to a wall outlet

 

Problem solved.  According to the technician, static caused by the surge protector builds up and causes the false error messages that can disable the printer.

Hope this helps!
