  2. Find the button below the word Auto.
  3. Press these buttons in the following sequence: [Clear], [Auto], [Clear], [Auto] NOTE: All of the lights on the Control Panel should go out and the LED Display should go blank. If the lights do not go out, then repeat step 3 until they do. It may be necessary to increase or decrease the pace of the [Clear], [Auto], [Clear], [Auto] sequence.
  4. Press the [10's] key one time and the [1's] key four times to enter '14' in the LED Display, as if you were to make 14 copies.
  5. Press the green [Start] button.
  6. Press the pink [Clear] button two times.
  7. The WorkCentre should now warm up and come to ready.

How do i reset H4-00 on a Sharp Al1566 Copier


H4 error is heat roller low temperature, try pressing the "#" key then "Interrupt" key then "C" key then "Interrupt" key to get into simulation mode and enter 14 and press start the follow instructions on screen (should be press ok). This will reset the code and restart the machine. When the machine restarts if the error was not mechanical the machine should go. If not you have one of two most likely problems; you need to reset the thermal cut-out on top of the fuser unit or the fuser lamp is blown.

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.

SHARP AR163 Displaying H2 error code


H2-0 Fusing unit temperature error
H4-0 The fusing unit doesn't heat up.
***ALWAYS DISCONNECT POWER WHEN WORKING ON MACHINE***
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.
Also check thermal fuse, if defective replace.
