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.
Hi, U2-40, mostly appears in sharp copiers when you installing new toner cartridge.the reason of this code is faulty CRUM chip because of different type of toner manufacture . you cane this problem by replace the chip in the new toner cartridge by the chip in old toner cartridge - the chip is located in the rear toner cartridge -
Cause-A toner cartridge of a different destination is installed. EEPROM trouble Check the destination setup. Toner cartridge CRUM PWB trouble MCU PWB trouble CRUM connector disconnection
Check and remedy- Install a specified toner cartridge. Check the SIM 26-6 setup. Replace the EEPROM. Replace the toner cartridge. Replace the MCU PWB. Check connection of the CRUM connector. Execute SIM 16.
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.
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!
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.
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.
