The repair guy was here servicing the machine and told me that it was a chip communication error. Is this true? If it is, how can I fix it? Does it mean I have a faulty toner cartridge? I put the old toner cartridge in and it is working fine.
If the toner is faulty, how can I prove to the person who sold it to me that the cartridge is bad?
The cartridge is faulty, in most cases not a genuine cartridge. If the copier works with the old one that means the "new" cartridge in defective. If you brought a original Sharp cartridge you should return that and ask for a new one.

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 -
From the service manual, doesn't look good.
A technicain will have to look at the printer.
RFID Reader I/F Error
An interface error was detected with the RFID reader device.
01 : communication error between the RFID reader and the engine PCB.
02 : the transceiver circuit error of the RFID reader.
03 : communication error between the RFID reader and the Tag chip.
04 : the RFID Tag detection error (more than 4 chips).
If rebooting the machine does not improve the symptom, you need to
check the device.
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.
If you get suppy memory error than replace the Toner cartridge.
On toner cartridge there is a copper connecting chip, that particular chip communicates with the printer.
However the chip on ptinter (EPM) which communicate with cartridge chip if that is faulty than you need to get printer repaired.
However first replace the cartridge.
Chip on cartridge may be faulty.
unfortunately i don't have the manual for this machine but on others it's a communication problem with the chip on the toner cartridge. if you use aftermarket/refilled toner you might have gotten a bad one. did this error show up right after you changed toner?
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.
