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.

Solution for SHARP AR 5127 error U2-40 call for service


This means that the cartridge's sensor is miscommunicating with the copier memory thus the code U2 -40. You should clean the inner sensor connector and the toner sensor of the spilled toner by low blower. Perform this code ;# , interrupt , C, Interrupt keys in that order and press 16 then Print key and the code will be cleared.

How to reset u2-40 for sharp AR266 photocopier


Since this appears to be a non-US model I can only base my response on the closest US body type AR-M237.

U2-40 means the countdown (CRUM) chip in your toner cartridge either broke or went to zero. If you can put in a fresh CRUM chip in your cartridge, that's great, otherwise you'll have to replace the toner cartridge.

L4-01 means main motor lock, probably due to a brownout or otherwise missed timing. You can probably get by with a power off and on. Not sharing your copier with other devices on the same outlet will also help here.

To reset error codes, put the machine in test mode with the four-key combo: # - * - C - * ... 16-Start clears your U2 trouble, 14-Start and 17-Start clear the rest. Then hit CA and allow your copier to reboot. Good luck!

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.

Error Code U2-40 on Sharp FO-DC550 fax machine.


That is a CRUM communication error. The CRUM is a chip that resides on the toner cartridge that keeps track of the toner usage and resets when a new toner is installed. If you replaced the toner recently it may be corrupt. If you got a refurbidhed toner they may have reprogrammed the CRUM incorrectly. Power supply problems often cause this error so check your outlet to make sure it is withinn the proper voltage range and also that it is not on the same circuit as other devices. Get a "real" surge protector designed for office equipment such as a smartpower. Try changing toners and using genuine supplies.

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.
