Hi, there is no error 4 alone it is usually followed by a H that is H4. Try to key in the following C Auto C Auto then enter 14 and press Copy key. If it was power low voltage , it will not re-appear but if it comes back then replace heater lamp and reset again.

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.

H4 error code


H4 is a Fuser Unit heating problem.
This reset is for another model sharp, see if it will work for you.

Press "Clear", "Auto Exposuer", "Clear", "Auto Exposure", the display will go dead... then press "14" (Like your going to make 14 copies), then press "Start".

Hope this works.
Good luck,
Mac

Cant get rid of blinking error message, nothing works


The [H4-00] system error popped up when the power went out of the house. I called Sharp tech support (1-630-378-3590) and was talking to their tech support in less than a minute.

The FIX? Just press the following keystrokes:
# * C * This will clear the display error, now press…14, then press the green button twice. This should let your printer start to warm up and you have fixed your problem.

H4-00 is a fuser related service code. you need to get into the simulation programs and run sim 14 to reset the code. Make sure there is no paper jammed in the fuser. (The hot part on the right side inside the door)

The correct buttons to push in order to get into the service mode on a 162D are [#] key, [*] key, [C] key and [*] key. Then you key in 14 - 00 and press the Start key. If that fails to bring your machine back on, you'll have to replace the fusing assembly.
