This function allows you to manually perform the same operation as when the toner cartridge is replaced with a new one. The purpose of this function is to provide an error resetting method in the event that the toner end display was not cleared because the new toner cartridge was not detected by the machine for some reason.

Reinstall the toner cartridge back into the drum unit. Shake the toner cartridge side to side before reinstalling. Make sure that you put in the toner cartridge. If the message is still showing, do this:
