CLEAR THE ERROR

Enter SIM


# - * - C - * - 16 - START

You must be reset your copier.
press,# -interrupt-c-interrupt.
Press 16 press start key.Then machine is ready.

Most commonly a toner cartridge issue. First try removing then reinstalling the toner cartridge and power off the machine. If this does not solve your issue then reset the error using the following:
Press these keys in sequence: #, interrupt, clear, interrupt. (screen should say service mode), enter 16, press print, it will ask are you sure? press yes.
This will reset the code so you can see if the code comes back
If it does then you have to change the toner, it has a defective crum (counter chip) on the back of it

Porfavor ayudenme necesito su ayuda urgentemente. este problema ya lleva 2 semanas asi y no me permite ni scanear ni imprimir ni nada.

ERROR CODE U2-4 COULD BE RELATED TO THE MEMORY BATTERY BEING DEAD ON TEH MAIN BOSRD IF IT IS AN OLD MACHINE SO YOU COULD CHECK THSI OR REPLACE AND TRY WITH NEW

In AR 275 Sharp copier U2 40 is very common problem, U have to only reset the above error code as fallows

press # then intrrupt then c them intrrupt then display will show simulation mode then enter 16 then press ok key

pl ask for any difficulty

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.
