View Full Version : Problem strikes on HP LaserJet 4P

Hi,

I have a HP LaserJet 4P, but all of a sudden it does not print. It displays on its little screen '50 SERVICE', so what is this problem? And when I open up the paper tray, the paper is jammed. It just can't get in to the printing place.

All help appreciated...

uh oh, 50 means the fuser's not working. It might be expensive. You can try a few things however. Clear the paper first then:
Turn the printer off for 20 minutes and allow the fuser to cool (this may resolve high temperature fuser errors).
Re-seat the cooled fuser assembly (this may resolve other non-temperature related fuser errors).
If the printer is plugged into a power strip or surge protector, plug it directly into a wall socket or different circuit (this may resolve errors caused by an inadequate supply of electricity).
Try a different power cord (the current power cord may be damaged).
Good luck
