TONER SUPPLY

1.

Roller Drive Mechanism

The toner supply clutch gear [A] turns when the main motor is on. T h e
transmission of this rotation to the toner supply drive gear [B] is controlled by
the toner supply clutch [C].
When the toner supply solenoid [SOLI ] energizes, the toner supply clutch
engages and starts turning the toner supply drive gear. The toner supply
drive gear turns the toner supply roller gear [D]. Toner catches in the grooves
on the toner supply roller [E]. Then, as the grooves turn past the opening, the
toner drops into the development unit.
The toner supply opening is the same width as A4 lengthwise (81/2" x 11") and
is located at the center of the developer tank. This is to reduce toner
scattering from both the ends of the development roller even if small size
paper is used continuously.
