When toner density is lower than a specified level, the toner
cartridge replacement indicator lights up to warn the user. If the

light.) If toner density is not back to specific level after two min-
utes, the ready indicator goes out and toner developer indicator
starts blinking, and the copier stops. Also when the toner quan-
