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.

H4 is nothing but an error code that appears due to power fluctation(in absence of a stabilizer). You please enter # interrupt-C interrupt -14-start to clear to clear the error

System error H4-00


Here is the text from a tip I have osted here on Fixya. It is for the Sharp AL Series copiers but your Toshiba is made by sharp and the reset procedure should be the same.

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.

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.

MESSAGE: SYSTEM ERROR (H4-00) REFER TU USER GUIDE


We had this problem when the power was fluctuating in our building. I called Sharp and they told me to clear this condition with the following code: #*C* and when the screen shows 00-00 enter 14 and press the green copy buton. This worked on the AL-1655CS. On the AL-1631 we had to do a similar thing: C<auto>C<auto> 14 <copy>

H4 error code


H4 is a Fuser Unit heating problem.
This reset is for another model sharp, see if it will work for you.

Press "Clear", "Auto Exposuer", "Clear", "Auto Exposure", the display will go dead... then press "14" (Like your going to make 14 copies), then press "Start".

Hope this works.
Good luck,
Mac

Sharp copier AL-1642CS


Here is what worked for me.
You need to alternate pressing the clear button then one of the auto buttons until the display lights turn off.

First press the clear button (red letter “C” on the unit) then the auto button. (below the word auto there are 3 buttons. Press the one on the far left that has no other markings on it. This will only take 2 or 3 times back and forth.

When the display is blank enter the number 14 (like you were making 14 copies of something) then press the Green (start?) button. Let the copier warm up about 30 seconds and try making a copy.

It worked for me. Still having trouble call Sharp USA 630-378-3590 or Canada 905-568-7140. They were quick and helpful
