To reset the H4 condition on just about any Sharp AL series copier press the following key's in sequence and as quickly as possible (with 4 seconds for the first 4 keys)
Press "C" then the far left key (exposure mode) then the "C" key then the far left again.
So in other words C, far left, C, far left
Some model's use 2 other initial codes, so you may need to use one of these 2 alternate codes to get your display to go blank. The rest of the procedure is the same.
Alternate codes are: #, * , C, * or pound,star,C,star and also
#, Interupt, C, Interupt
If done correctly the display should go blank.
Now key in 14 as if you were going to make 14 copies.
Now press the print button.
The machine should reset and the code should be gone.
9 times out of 10 this is a false code that pops up due to power surges or noise.
If the code comes back this means you have a heater lamp or thermal fuse (more common) failure in the fusing area and will need service.
Good Luck and Thank You for using Fixya.

What does code: H4-00 mean


The H4-00 is a low temp error in the fuser. This can normally be reset by doing the following at the machine:

On the button panel hit
pound, star, C, star
then enter 14, hit start, then execute on the screen.

This should clear any one-off errors

H4 ERROR CODE


press on the keypad, # * C * the machine will enter a diagnostic mode. Then enter 14 as if to make 14 copies. You may then have to press 1 and execute the program. But that will clear the H4 code 99 percent of the time. Once you enter 14, just press start and follow the directions on the screen. An H4 means the machine was just slow to warm up. It can be a fuser error, but there actually being a problem is extremely rare. Performing a clear 14 will almost always clear that.

Showing h4


If your machine is AR-5316,
The problem is in the fusing unit try these steps:

STEP1: Press continuously CLEAR then INTERRUPT then ZERO then INTERRUPT

STEP2: The panel display will turn off it means that you are inside the simulation if not repeat again step1.

STEP3.Then type 14 then press the print button

If these steps doesn't work you must call an authorized serviceman to check your machine, maybe something is busted on the fusing unit like thermostat or fusing lamp.

Hi,

H4 indicates there is a fuser error.

Try resetting it by the pressing the following buttons on the display in sequence,

#, interrupt, Clear, interrupt,

display should go dead,

enter 14,

then press print, This will clear the error code

press CA to get out and return to normal.

However if there is still a problem with the fuser, the code will return. Then you may need to have a tech look at what is the problem.

Hope that helps...
