H2 error code on sharp ar-m160

Fixing unit is bad the very hot part of the machine is bad replace the fuser unit

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

"Press # - Interrupt - C - Interrupt -14 - Start key Thermistor open
The thermistor is open. The fusing unit is not installed.

Below are the F2 errors and causes for Sharp AR-M160

"F2-31" Image density sensor fault
"F2-32" Drum mark sensor fault
"F2-33" Grid voltage correction problem
"F2-35" Grid voltage correction problem
"F2-37" Drum mark sensor fault

Cause : CRUM chip defect OR Improper developing unit
Check and remedy : As you have already replaced the tonner, we can suggest Replace the CRUM chip,Replace the developing unit

H2 means termistor damaged enter code 14 .if not solved change termistor

enter the simulation mode:
"#" key Interrupt key "C" key Interrupt key
press 14 and START key
the copier should restart in most cases.

if not:
There is a problem in the fusing area, bad Thermistor, defective ThermalFuse, defective heating lamp.

It's not developer light.
It is drum unit light and maintenance.
You have to replace the Drum, Blade and Developer.
After changing them you have to reset the maintenance, drum,developer counter.
This procedure must be made by a copier tech.

But if you still want only the developer the code is AR-202D

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.

Clearing a trouble code on a AR-M160 is a little different than the AR160.

Try "#" "interrupt" "clear" "interupt" "1" "4" "start key"

This should clear the error. Even if you replace the fusion unit you will need this code to clear the error

I HAVE AN ERROR CODE L6 ON A SHARP AR-163 PDIGITAL IMAGER. WHAT IS CAUSING THIS ERROR AND CAN IT BE REPAIRED IN-HOUSE?

U2 is normally a user error (hence U) check that all the doors are closed fully and just recheck the toner installation. If this is all correct it might be a slight possibility that the toner cart is faulty.
