Transfer Process Errors
Resolving the Upper and Lower Film errors
Symptom: Lower or Upper Film Sensor may have failed.
Step Procedure
1 Verify if the Lower Film Sensor (840199) has failed.
a. Check the voltage for the Film Sensor where it connects to the Lamination
Board.
b. Place a Film mark over the Film Sensor. (Note: The voltage should be
less than 1 VDC.)
c. Remove the Film mark from the Film Sensor. (Note: The voltage should
be greater than 3.4 VDC.)
d. Replace the Sensor if the voltages are incorrect.
2 Verify if the Upper Film Sensor (D841023) is out of calibration. See the
Reviewing the Transfer Station Components photograph to see the location of
the Upper Film Sensor on page 265.
a. Position the Transfer Film so that the clear portion is between the slotted
optical Sensor.
b. Turn the potentiometer on the Sensor Board with a small slotted
screwdriver until the LED on the Board turns ON.
c. Back the potentiometer off until the LED just turns OFF.
3 Verify if a wire has broken off the Ribbon Drive Motor D840980.
a. Verify that both motors are connected to J66 on the Lamination Board.
b. Disconnect the motors. (Note: 9-VDC battery connected to the motor
leads should make it turn.)
c. If the motors do turn, verify the wire connections at the motor and replace
or solder those connections as needed.
4 Verify if the Print or Lamination Boards has failed.
a. Replace the Print Board. See Replacing the Main Print Board (A000271)
procedure in Section 5, page 367 for instructions.
b. Replace the Lamination Board. See the Replacing the Lamination Board
(140402) procedure in Section 5, page 368.
