Toner Cartridge
Outline The toner cartridge includes a toner container with stirring plate, a toner
feed roller, rubber blade, and developing cylinder. The developing
cylinder, toner feed roller, and stirring plate receive rotational drive
through the white toner cartridge drive gear on the photoconductor
drive shaft. Toner carousel motor M3 supplies this drive in sync with
the drive supplied to the photosensitive drum by drum motor M4.
This internal drive train of the toner cartridge engages with the toner
cartridge drive gear only during the “press” position
Note: See “Toner Carousel Control” later in this chapter for full
description of “home,” “stop,” “press,” and “fetch” positions.
Toner Stirring
Function
The toner cartridge stirring mechanism consists of the stirring plate and
toner feed roller and helps in supplying toner from the toner container
to the developing cylinder. The stirring plate agitates the toner within
the container. The feed roller is responsible for applying a thin layer of
toner onto the developing cylinder.
