When a give the printer to print the monitor shows H4
The problem is in the fusing unit try these steps:
STEP1: Press continuously CLEAR then INTERRUPT then ZERO then INTERRUPT
STEP2: The panel display will turn off it means that you are inside the simulation if not repeat again step1.
STEP3.Then type 14 then press the print button
If
these steps doesn't work you must call an authorized serviceman to
check your machine, maybe something is busted on the fusing unit like
thermostat or fusing lamp.
