OF8 ARCING RAP
This RAP is used when Arcing is occurring
between the Print Drum and the contacts
which supply the Charge voltage.
INITIAL ACTION
Inspect the Toner Collector for layers of color
and black toner in the toner collector. This is
sometimes referred to as the “sand-art” effect.
It is caused by solid development during the
copy quality setup process.
If the Charge Scorotron or Charge Grid
connection is faulty, it can result in no or very
low charge. Since this is a “write black”
printer,” the print drum will develop a solid
image when there is no charge.
PROCEDURE
Check and clean the Charge and Grid
contacts located on the right side of the Print
Drum. Check and clean the Charge and Grid
contact points on the frame side of the printer.
Remove the Fuser Module. Clean the bracket
that holds the Erase Lamp assembly. Look for
fibers from the exit discharge brush.
If the problem persists, refer to BSD 9.4 in
Section 7 and check the Red leads to the Print
Drum Module for an open.
Replace the Print Drum Module.
