Hi I have problem with my photocopaier. Sharp ARM236. It shows Code: U2-40


U2-04 EPROM error
U2-11 Main counter error
U2-12 EPROM error

As you can see there are many U2 error codes. Needless to say, find your code and the replace the bad part. The battery is on the main board. The EPROM is on the main board.
If you find your code, replace the part and error still remains -- replace main board.

Service code U2-05? How do you fix this and do i need to call a professional?


That normally means the hard drive has failed. You can remove the hard drive and it will work except for I believe it is stapling and some other finisher feature.
What you can try is this.
Press # * C * , or as sharp calles it P * C *. The machine will enter diagnostics.
Then enter the number 16 as if making 16 copies. Then press start.
It will say something like U2 trouble clear.
Press start, then select 1 for yes and press start again. Repeat that a couple of times then press clear a few times or turn the power off then back on.

Photocopier not working. Sharp AR-335 Code U2-00 Please help, Thank you


U2 is an EEPROM error. The software isnt loading correctly.

2 things to try.

1. Press P * C * or # * C *. However your machine it labeled. That will enter diagnostics. You then want to enter 16, then press enter and start. That is the simulation fault clearance for a U2. If that does not work then I would suggest removing the back cover and remove and reseating the memory chips.
After you remove and reinsert the chips,do that simulation 16 again.

Error code U2 on a AR201 copier


To find out the sub code for the U2 error hold down the Start key. Below is a list of the errors:
U2-04 EEPROM serial communication error
U2-11 Counter check sum error
U2-12 Adjustment value check sum error (EEPROM)
U2-40 CRUM communication error

To clear the U2-40 error try pulling out the toner cartridge and firmly reinstalling it. If that doesn't work you must install a new toner cartridge. There is a CRUM chip on the cartridge that keeps up with how many impressions have been made with that cardridge. You cannot "refill" these cartridges without replacing the CRUM. This problem occurs frequently with remanufactured cartridges.

To clear other U2 errors you must enter simulation mode.
Perform the following procedure to enter the simulation mode.
Clear key - Interrupt key - "0" key - Interrupt key - 16 - Start key - Start key. The unit should reset.
