Action
Check the erase lamp lens assembly
for any signs of paper dust, toner
buildup or any other contamination.
Clean with a soft cloth or replace the
lens and lamp assembly which are
provided together in a kit. If the lens
is clean then check the erase lamp
assembly for failed erase lamps. If
defective, replace the erase lamp
assembly.
Check the fuser assembly for signs
of toner contamination. The hot roll
especially might cause toner to be
retained and deposited on the page.
Action
Check the right end of the transfer
roll shaft for signs of wear or
contamination. If incorrect, replace
the transfer roll.
Check the right side transfer roll arm
assembly bearing for any signs of
wear or contamination. Also check to
ensure the transfer cable is firmly
attached to the bearing. If incorrect,
reposition the bearing to make
contact with the wire. Replace the
bearing as necessary. Check the
connection of the transfer roll
assembly cable to the transformer
on the HVPS board. Check the
continuity of the cable from the
bearing to the spade terminal on the
cable. If incorrect, replace the right
side transfer arm assembly. If
correct, replace the HVPS.
