CHAPTER 11 INSTALLATION
4) Apply drum cleaner lubricant evenly along
the No. 2 blade (front, rear).
· Be sure to shake the drum cleaner
lubricant container well before
application.
· Be sure to apply the lubricant to the
face, back, as well the edge.
· Be sure to apply the lubricant as if to
tap lightly on the edge. Do not rub it so
as to avoid chipping the edge.
5) Dry wipe the sensor face of the black toner
concentration sensor.
· Do not use alcohol.
6) Mount the black toner concentration
sensor unit, and connect the connector
with a screw.
· During insertion, take care not to make
contact with the photosensitive drum.
Caution:
If the No. 2 blade comes into contact with
the photosensitive drum during insertion,
lubricant can spread to the photosensitive
drum, causing white spots in copy
images.
7) Remove the screw, and pull the
photosensitive drum cleaner to the front;
then, shift it counterclockwise, and then
slide it out.
