Check the heater lamp blinking
with SIM 5-2.
When the lamp blinks normally:
Check the thermistor and the
harness. Check the MCU PWB
thermistor input circuit.
When the lamp lights up instead
of blinking:
Check the lamp control circuit of
the power supply PWB and the
MCU PWB.
Clear the trouble with SIM 14.

What does code H 3 mean when the copier is turned on?


A H3 code means that there is a problem with the fuser unit. You can try to clear th code in service mode, but it may come back. You may have a blown thermister or thermal fuse or the fuser heat lamp. Good Luck

H 4 code flashing


The H4 code indicates the fuser may have blown the thermistor. It also could be a false error code. Try this series to clear the error and if it returns, then you'll know for sure the fuser is the culprit. To reset press the following buttons:
  1. Press this sequence: CLR-Exposure-CLR-Exposure
  2. The display will go blank
  3. enter "14", press "PRNT"
  4. Press "CLR" several times to exit.
Give that a try and good luck.

I have error H 2, what to do?


This error indicates: H2-0 Fusing unit temperature error

Unless you are technically capable, you will want to have a qualified technician diagnose and repair.

If you want to try and diagnose it yourself, follow these directions.
You have to reset fuser errors with simulation 14. Push P * C * then 14 then Start (the button you use to make copies) and it should reset the code. If not then replace the fuser.
SM 5-1 should turn the lamp on. If lamp blinks on and off it is the thermistor, if it does not it is the lamp, but check the contacts on the lamp/fuser -- they have been known to erode.
Also check thermal fuse, if defective replace
***ALWAYS DISCONNECT POWER WHEN WORKING ON MACHINE***

The fuser temperature is low.
Use sim. 5-02 to check blinking of the heater lamp.
if it blinks normally check the thermistor and the harness.
If it not lighted check the heater lamp and thermostat if its defective replace the heater lamp or the thermostat.
