H4-00


H4-00 on Sharp means that the temperature inside the printer is too low. That is usually the fuser lamp, and rarely the temp sensor.
When this happen you need to have the fuser unit replaced, if that does not fix the problem the technician will replace the temperature sensor.

Code: H4-00, H4-0Q


H4-0 The fusing unit doesn't heat up.

You have to reset fuser errors with simulation 14.
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.
