The bias from the fuser
high-voltage PWB cannot
be applied to the fuser dis-
charging needles in the
fuser unit.
Check if the bias contact con-
tacts the fuser unit or the con-
nectors on the fuser high-
voltage PWB are properly
connected. If the bias is not
output from the fuser high-
voltage PWB, replace the
fuser high-voltage PWB.
8 Detaching and Reattach-
ing the high-voltage PWB
The high-voltage PWB is
faulty.
Replace the high-voltage
PWB.
