and locked in the down position. If
the arm is not locked down, check to
ensure the arm is not broken and will
lock into the EP frame correctly.
Check the left transfer arm assembly
spring for proper operation.
Check the right transfer arm
assembly to make sure it is fastened
and locked in the down position. If
the arm is not locked down, check to
make sure the arm is not broken and
will lock into the EP frame correctly.
Check the right transfer arm
assembly spring for proper
operation. For any background

contact to the HVPS board is correct
and that there is approximately 0
ohms resistance between the
transfer roll shaft and the HVPS
contact. If correct, go to
Quality - Background" on
page 2-114.
Check the voltage at J25-3. The
voltage changes from +24 V dc with
the printer idle to 0 V dc when the
printer runs the print test. If the
voltage is incorrect, check the
continuity of line J25-3 in the front
cable harness to the HVPS. If there
is no continuity, replace the cable
harness. If there is continuity,
replace the HVPS. If the problem
continues, replace the system board.
