3.19 OPC DRUM CHANGE

3.19.1 SETTING POWDER APPLICATION PROCEDURE
1. Apply the setting powder to the drum by tapping the powder bag across the
drum surface so the area being applied turns white. Continue applying the
setting powder until the entire length of the drum is covered about 1/4 of the
total surface of the drum as shown in the illustration.
NOTE: Waste toner can be used if no setting powder is available.
Waste toner has a charge and will be attracted to the drum
surface. Dirty background may occur if waste toner is used.
2. Install the new drum in the OPC unit so that the powdered area (in bold below)
faces the cleaning blade.
3. Rotate the drum once along its normal rotational direction (arrow shown below),
so that it stops again at the same position. Be sure not to rotate the drum in the
opposite direction.
CAUTION: IF THE SETTING POWDER IS NOT APPLIED, THE DRUM'S
CLEANING BLADE MAY TURN OUTWARD, CAUSING A
DRUM CLEANING FAILURE.
