This should do it.

Performing a Fault Reset 14 will reset your WorkCentre and will help to clear error codes.

  1. Find the pink Clear button on the Control Panel of the WorkCentre.
  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.
  8. If the above steps do not clear the error code, repeat steps 3 to 6 a second time.

SOURCE: error code:H4-00

That copier is kind a old. The H4-00 is a fusing error code. The problem is that the fuser is not heatting up right. Mostly it is that
the fusing lamp is broken or the thermal fuse is blown. It will not reset untill the problem is resoloved

Our copier is an AR-208D & it has a error code of H4-00 displayed. Can we fix it?


In most cases the flashing H4 or H then 4 code on these machines is caused by voltage fluctuations or surges. Normally there is nothing wrong with the machine and the code is easily reset. Here is the procedure:
Press the following key's in sequence and as quickly as possible (with 4 seconds for the first 4 keys)
Press "#" then the " * " (star) key then the "Clear" key then the " * " key again.
So in other words #, star, C, Star
If done correctly the display should go blank.
Then key in 14 as if you were going to make 14 copies.
Now press the "print" button
The machine should automatically shut down and restart with the H4 code being gone.
If the H4 code comes back after reset then in this case you have a fusing unit problem and will need to have the unit serviced.
Good Luck and Thank You for using Fixya.

What does an error code H4-01 mean on a Sharp MX4501N copier? The machine no longer copies, simply displays: Call for service Code H4-01.


Fuser Heater failure. The fuser is the part of your machine that heats up and "fuses" the toner onto the paper. It is located right near where the paper exits the copier. This error code means that the fusing unit is not heating up as it should. The most common failures in order of ocurance are thermal fuse, thermister and heater lamp. In any case you are going to need a service person to come out and diagnoe which part has failed, replace the part and reset the code for you. Should not be more than say $200 to repair.
Good Luck and Thank You for using Fixya.

Error code H4 on Sharp AL-1641CS?


Usually a flase code on these models. Try clearing by pressing "C" then far left key (Exposure Mode) then "C" then far left again. Must be pressed quickly and if done correctly display will go blank. Then key in 14 as if making 14 copies. Then press Print.
Short Version: C, far left, C, far left, 14, print
If code returns then you have a fusing unit problem but 9 times out of 10 this is just a false code.
Good Luck

I have a sharp copier, model AR-285, H4-01


H4 error pertains to lamp errors.

that would either be the copy lamp or the heater lamp.

check both lamps.

with heater lamps,it's usually caused by either a broken heater lamp or a dirty thermostat on the heater roller assembly.

It should be done quickly. If it's done quickly enough all lights on display should go off.

5.Enter number 14 (as if you are making 14 copies).
6. Press START/COPY button.

The machine goes back to normal. If not, thermistor on the fuser (heater) should be replaced.

Cant get rid of blinking error message, nothing works


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)
