Air Flow Around The Drum - Gestetner B070 Service Manual

6.11.5 AIR FLOW AROUND THE DRUM

The drum cooling fan [A] draws cool air through the filter [B] and sends it to the
center of the drum [C], then over the charge corona unit [D].
Holes in the flanges on both ends of the drum allow air to pass through the drum to
cool it. After the air has passed through the center of the drum, the exhaust fan [E]
draws the air out of the interior of the machine, through the toner filter [F] to remove
free floating toner, through the ozone filter [G] to remove ozone, then finally out of
the machine.
To keep the temperature inside the machine constant, the drum cooling fan turns
slowly during standby, but turns faster during copying.
NOTE: This ozone filter does not require replacement.
