，，U2-40 CRUM communication error
CRUM通訊錯誤
U2-40 error try pulling out the toner cartridge an d 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.
