Toner flow

A. Toner cartridge
• When the toner cartridge is mounted in the machine, the shutter opens, so that the toner
hopper can be replenished with toner.
• Rotation of the toner cartridge motor causes the toner cartridge to rotate. The interior of
the toner cartridge is in spiral form. As the toner cartridge rotates, toner inside the toner
cartridge is conveyed toward the toner replenishing port located at the front side, so that
the toner hopper is replenished with toner from the toner cartridge.
• The toner cartridge is not provided with any mechanism that detects the amount of toner
left in it. No means is available to detect the amount of toner left inside the toner car-
tridge.
B. Toner hopper
• Rotation of the toner supply motor causes the toner agitating blade and toner conveying
screw inside the toner hopper to rotate.
• Toner conveyed into the toner hopper is agitated by the toner agitating blade.
• As the toner conveying screw rotates, toner is conveyed onto the toner replenishing port
located at the front side inside the toner hopper, so that the toner is fed into the develop-
ing unit via the toner replenishing pipe.
• The toner hopper is provided with a toner empty sensor that detects the amount of toner
left in the toner hopper.
The toner hopper is replenished
with toner from the toner cartridge.
