Toner Cartridge Detection - Gestetner G060 Service Manual

DEVELOPMENT
Shutter Mechanism
[D]
[F]
The development unit and toner attraction pump each have a shutter mechanism.
When the development unit is placed in the machine, the protrusion [A] on the
development unit opens the shutter [B] in the pump, and the protrusion [C] on the
pump opens the shutter [D] in the development unit. When both shutters are open,
toner can enter the development unit from the toner attraction pump.
When the development is removed, the shutter spring [E and F] pulls and closes
the shutter.

6.5.7 TONER CARTRIDGE DETECTION

[A]
A memory chip [A] on each toner cartridge stores the total 'on' time of the toner
supply clutch. This is used to calculate the amount of toner remaining in the toner
cartridge. The chip also detects whether the cartridge is installed (if the cartridge is
not installed, the machine does not detect a signal from the memory chip).
