BULLETIN NUMBER: 6645/6655-008 04/15/94
APPLICABLE MODEL: FT6645/6655
SUBJECT: PICK-OFF PAWLS
SYMPTOM:
1. The pick-off pawls touch and damage the transfer belt.
2. Toner drops onto copies below pick-off pawls.
CAUSE:
1. While removing jammed paper around the drum, the operator moves the pick-off pawls out of the
correct position.
2. Toner accumulates on the head of the pick-off pawls and drops to the copy paper below.
SOLUTION:
1. The shape of the pick-off pawls have been changed to prevent them from contacting the transfer belt.
2. The material of the pick-off pawls has been changed from metal to resin.
NOTE: Because the material of the pick-off pawls has changed to resin, the pick-off pawls will wear down
with long usage. To prevent drum filming and the formation of gray lines on the copy image, the
pick-off pawls must be replaced every 240K copies.
