Question about Sharp AR 201 Copier
My copier has thrown up an error code U2 any ideas on how to clear the error?
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.

* Entering the simulation mode
1) #/P key (program) ON → Asterisk (*) key ON → CLEAR key ON →
Asterisk (*) key ON → Ready for input of a main code of simulation
Simply # * C * and the machine will enter simulation mode.
Then enter the number 16, which is U2 code correction, follow what the screen says, Normally just press start and the machine will reset.
U2 codes are software glitches. A U2 40 is a CRUM fault which is a drum or toner chip problem.
Sim 16 almost always clears them.
