(18) Insert 2 LTR (A4) size papers (brand new) under the
Bias Charge Roller passing through the Discharge
Light slit as illustrated.
Note:
The width of the paper should cover the entire width
of the Bias Charge Roller.
(19) Lift both sides of the papers and cover the Bias
Charge Roller, then place the OPC Drum Shaft
Holder on top of the papers to act as a weight.

Drum Starting Powder. Apply additional Drum Starting
Powder onto the surface of the OPC Drum if required.
Note:
Do not touch the surface of the OPC Drum with bare
hands when removing or reinstalling it. Grease from
fingerprints will affect copy quality.

The OPC Drum is sensitive to light. To prevent optical
exposure problems, do not expose the OPC Drum to
direct sunlight or bright light (even if it is a 1000-Lux
fluorescent lamp).

Holder.
(22) Spin the OPC Drum in the arrow direction, turning by
the edge (approximately 1 inch) with your fingers to
collect the powder onto the cleaning blade and clean
the OPC drum surface. Spin the drum until both
papers are released from the Bias Charge Roller.
Caution:
If it does not spin smoothly, the Cleaning Blade or
Gear(s) may be damaged. Inspect and repair before
proceeding.
