Question about HP LaserJet 2840 All-In-One Printer
This is due to a hardware failure, the scanner assembly and the formatter board will need to be replaced.
Try doing a hard or reset or nvram:
1. Turn the printer off
2. Hold down the enter and the * button
3. Reboot the printer while holding the buttons and hold until permanent storage is displayed. Let go of the buttons and wait for the ready message on the display.
if this does not work contact hp 1800-334-5144.
