Mon copieur affiche un code d'erreur h4


H4 = abnormally low heat temperature detected.

This can be caused by the following

Blown Heat Lamp
Blown Thermostat

Sometimes the code will be shown if a paper jam has got stuck inside the heat unit, blocking the sensor.

try resetting the code with the following sequence:

Press: Clear, Density Select, Clear, Density Select, 14, Copy Button.

Hopefully the machine will reset. If not, it may be possible to reset a blown thermostat by pressing the button on the back (it pops out if it detects overheating). This should really only be carried out by an engineer.

Hope this helps

Sharp AL Series Copier H4 H-4 service code reset


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.
This works on the following models:
Sharp AL1000, Sharp AL1010, Sharp AL1020, Sharp AL1041, Sharp AL1200, Sharp AL1215, Sharp AL1220, Sharp AL1250, Sharp AL1251, Sharp AL1340, Sharp AL1451, Sharp AL1520, Sharp AL1521, Sharp AL1530CS, Sharp AL1540CS, Sharp AL1551, Sharp AL1551CS, Sharp AL1631, Sharp AL1641CS, Sharp AL1651, Sharp AL1651CS, Sharp AL1655CS, Sharp AL1661, Sharp AL1661CS

I have a Sharp Al 1566 Photocopier,Printer,Scanner and it has encountered a problem which is SYSTEM ERROR (H4-00) so how can I fix the problem?


H4-00 = Low heat roller temperature detection. This is usually caused by either a blown heat lamp or a blown thermal fuse.

Sometimes the error can show up for no particular reason. Try resetting using the following sequence:

#,*,C,* (hash, star, clear, star) then enter '14' and then press the start button.

The machine will reboot. If the code comes back you'll need to check the lamp and fuse for continuity (having removed the fuser from the machine first!)

Hope this helps.

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.

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.

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...

  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.
