Question about Canon imageCLASS MF5770 Black and White Copier
I only use this unit to make copies. It is not hooked up to a phone line or computer. When I came into to work today that message was on and the unit doesn't do a thing. Yes, I unplugged it but no help. That was Canon's tech help. The unit is 13 months old--just out of warranty and lightly used.
Any help is appreciated. Joe
You could try to take the battery out ,to the machine do a reset.that message is firmware problem , if still the same only technician of CANON can repair the problem
