U2 is usually a memory type issue, have you unplug and then plug back in after 1 hr.

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.

U2-40 error etc.


U2 is a memory error. It's either the RAM or the ERPROM. A techincian has to look at it and determine which part it is and replace it. The copier won't run until it is fixed. It could be a loose memory board as well.

What's U2 code and method for solution


U2 can have several indications.
The most likely one is that the chip that is on the back of the toner cartridge is not seated properly or has failed.
Try with the machine off, removing and inserting the toner cartridge several times to clean the contacts, next step is to try a new toner cartridge.
There is also a connector on the back frame of the machine that may be dirty or going bad.

U2-40


The code was not included among the Status Code Indicator RAPS. U2-40 is a Communication Error between the Main PWB and the CRUM on the Toner Cartridge (CRU).

Sounds like the toner cartridge is not seated or is defective.
What that message is saying is that the small chip on the back of the toner cartridge is not communication with the processor board.
