Remedy
Check the harness connections of the
registration front sensor PCB ASSY,
registration rear sensor PCB ASSY and paper
eject sensor PCB ASSY, and reconnect them.
Ensure smooth operation of the registration
front actuator, registration rear actuator or
paper eject actuator and ensure they are
not catching in any positions.
Check the sensor performance following
the procedure described in
mode 32". If any problem occurs, replace
the eject sensor PCB ASSY.
Check the sensor performance following
the procedure described in
mode 32". If any problem occurs, replace
the registration front sensor PCB ASSY.
Check the sensor performance following
the procedure described in
mode 32". If any problem occurs, replace
the registration rear sensor PCB ASSY.
Re-assemble the registration ground
spring. (Refer to Fig. 1-3.)
Replace the main PCB ASSY.
