Welcome to Fixya
Try to do Semi-reset on the system.
1. unplug the power at the back of the printer and
2. press # and "6" at the same time on the front panel
3. while holding these two buttons , replug the power at the back and keep holding till you see "semi full reset" on the screen
4. Now release the buttons and let the reset complete...you may be prompted to enter the language again etc....
Even if this doesnot work...try a "full reset"
5. Which is done by pressing "#" and "9" simultaneously with the same procedure.
If same thing will happen after performing this resets. Then you need to call HP support since this is already a firmware problem.
