Development Unit Toner Suction - Gestetner B070 Service Manual

6.12.6 DEVELOPMENT UNIT TONER SUCTION

To ensure that the fine-grained toner does not scatter and blacken the interior of
the development unit, a toner suction assembly reduces the pressure inside the
development unit.
Below the development unit [A] the toner suction pump [B], driven by the toner
suction motor [C], draws air out of the development unit along with any airborne
toner. The toner is sent to the development unit waste toner bottle [D] on the right
side of the machine.
The toner suction motor switches on and off with the development motor.
The toner suction motor and the waste toner bottle both have near-end and end.
When an end alert is issued for either the development unit waste toner bottle or
the toner suction motor, a message is displayed on the copier LCD panel. (See the
next page.)
