Specifications

13-13. Toner Suction Fan Motor

•

This copier is provided with a Suction Duct under the 2nd Sleeve/Magnet

Roller. Toner particles from the Developing Unit are drawn in through the

Suction Duct so that they will not fall over the Pre-Image Transfer Guide

Plate and Image Transfer/Paper Separator Coronas Unit.

•

The toner particles are drawn through the Suction Duct and collected by

the Air Filter as the air is drawn out of the copier by Toner Suction Fan

Motor M20.

•

M20 is energized and deenergized by the signal output from pin 49 of IC5A

on Master Board PWB-A.

M20 is energized at the same time when PC Drum Drive Motor M5 is

energized (p. M-26).

M20 is deenergized approx. 4,600 msec. after the trailing edge of the last

copy has moved past Paper Exit Sensor PC36.
