It sounds like you have a fuser problem. "H" = Heat

Sharp copier SF-2025 displays an error code H4


H4, not heating up, replace fuser unit complete or work with hivolts and replace an expensive and tricky lamp/thermister . wont be cheap.

. Here use the reset for it first, sometimes power surges can just flip them out but most times will just reappear shortly after reset, indicating the want of a working fuser assembly

Fuser (not fuse) is the hot bit with rollers at paper exit if code fails it needs to be replaced, wont come cheap no matter how you approach it

C-Exposure key-C-Exposure key-14-copy key to clear ... but it will come back I bet...

Sharp sf-7100 / status code


H4 means the fuser can't heat up. The fuser lamp probably burned out. Sorry, nothing can be done without tools and new lamp

MY SHARP AR5316 DISPLAY H4 WHEN I PUT IT ON


Here is the process

  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.
