BULLETIN NUMBER: 6645/6655/6665-036 03/13/95
APPLICABLE MODEL: FT6645/6655/6665
SUBJECT: DUPLEX PAPER END SENSOR FEELER BREAKAGE
SYMPTOM:
The customer pulls out the Duplex Unit and the Duplex Paper End Sensor Feeler breaks off. The machine
then displays "Paper in Duplex" even though there is no paper present in the Duplex Tray.
CAUSE:
1. The Duplex Entrance Sensor Bracket [A] is too close to the Entrance Sensor Feeler [B]. This causes
the Entrance Transport Assembly to remain down even if the front door of the machine is open. When
this condition exists, pulling out the Duplex Unit will break the Duplex Paper End Sensor Feeler.
2. The Arm Release Spring [C] has insufficient tension to raise the Duplex Entrance Assembly when the
copier front door is opened. When this condition exists, pulling out the Duplex Unit will break the Duplex
Paper End Sensor Feeler.
FIELD COUNTERMEASURE:
1. Re-form the sensor bracket [D] toward the right slightly (3 ~ 5mm).
2. Re-form the upper position of the spring [C] to increase spring tension.
