Sharp AL1644 Hi, I have a Sharp AL1644 with the code H2. I have been told that there is no reset code for this machine and that I have to replace the fuser, could you either confirm this or let me have the reset code? Thank you Carole

Hi

Should probably read H2-00, which is your thermistor in the fuser. Open door on right, three screws hold the fuser in (hot bit), release fuser slightly, being careful as it is still connected, the thermistor is sat in the top, you should be able to reset it by pressing the little button and you should here it click. re-fit fuser and secure.

To reset the code, press these buttons:
Hash, interrupt, clear, interrupt., enter 14, then the print button.
Cheers

Hi Ambroise,
The error H2-00 means there's a problem with your thermostarts/fusing unit.You need to check them for they may be blown.Replace the fuser if damaged.To reset the code,push P*C* then 14 and then press on the start button[the one you use for copies making].The code is reset.If not,then you need to replace the fuser.

Hope this helps.Thanks!
Please rate this answer.

The fuser codes are only H2,H3 and H4. To reset , press C, Exposure, C, Exposure.Display goes off enter 14 press print.

Hi,
this is a fuser error message. You must fix the problem causing the fuser to post an error. Then clear the message.

Sharp Fuser
H2-0 Fusing unit temperature error
H4-0 The fusing unit doesn't heat up.
***ALWAYS DISCONNECT POWER WHEN WORKING ON MACHINE***
You have to reset fuser errors with simulation 14. Push P * C * then 14 then Start (the button you use to make copies) and it should reset the code. If not then replace the fuser.
SM 5-1 should turn the lamp on. If lamp blinks on and off it is the thermistor, if it does not it is the lamp, but check the contacts on the lamp/fuser -- they have been known to erode.
Also check thermal fuse, if defective replace.

In AR 275 Sharp copier H2 00 is very common problem, U have to only reset the above fuser error code as fallows

press # then intrrupt then c them intrrupt then display will show simulation mode then enter 14 then press ok key


If this is not enough then press press thermostat on fuser unit by removing the unit from machine this requires tech knowledge

OR you can try by replacing thermistor of fusing unit

If by above procedure the prob is not solved then and then you replace the fusing lamp

Even though u can check the lamp by removing back cover and turn on the machine u can observe the light of fusing lamp

pl ask for any difficulty.

You have an open Thermistor in the fuser unit or the code is false caused by power surge. To reset it, press P*C* and hit 14 start, then hit either ok or start again and machine chould reboot and clear code. If code returns then the thermistor is bad. You will have to have your local dealer replace either the themistor or the entire fuser unit.

Sounds like a tough one, take off the back cover and make sure all connectors are making good contact. You may have a fault in the main logic board.
This might need a tech to check out.
Hope that helps...

You have a thermistor open. That means that the device that reads the temperature in the fusing unit, has broken. You will need to replace the fusing unit to fix this problem. You could try a Sim 14 reset. Push P * C * then 14 then Start (the button you use to make copies) and it should reset the code. If not then replace the fuser.
