Toner Container
Toner cartridge is îš¿lled with toner and supplies to the drum unit.
Toner cartridge
The toner in the toner cartridge is fed to the sub hopper and then to the developing unit by
the toner feed screw. The toner presence/absence in the sub hopper is detected by the sub
hopper toner sensor (TS2) which is a magnetic permeability sensor.
If the developing unit toner sensor (TS1) detects the absence of the toner in the developing
unit, the hopper motor (M7) drives to rotate the toner feed screw to feed toner in the sub
hopper to the developing unit. Also, if the sub hopper toner sensor (TS2) detects the absence
of the toner in the sub hopper, the bottle motor (M7) drives to rotate the toner cartridge to
feed the toner in the toner cartridge to the sub hopper.
If the sub hopper toner sensor (TS2) keeps detecting the absence of the toner for more than
the speciîš¿ed period of time, no toner in the toner cartridge is assumed and the message to
replace the toner cartridge will be displayed. Also, if the developing unit toner sensor (TS1)
keeps detecting the absence of the toner for more than the speciîš¿ed period of time, no toner
in the developing unit is assumed and a "No Toner" error message will be displayed.
