BULLETIN NUMBER: 6645/6655/6665-041 05/12/95
APPLICABLE MODEL: FT6645/6655/6665
SUBJECT: RUST ON FEED CLUTCH FACE-PLATE
SYMPTOM:
"Z-fold" paper misfeed in section C when feeding from internal paper trays (feed stations 1, 2 or 3).
CAUSE:
The paper Feed Clutches (AX210037) have a build-up of rust on the face-plate. This causes improper paper
feed.
FIELD COUNTERMEASURE:
1. Clean the clutch surface with 600 grit emery cloth.
Rinse the clutch surface with alcohol.
Clean the clutch with a dry cloth.
Apply a small amount of lightweight oil (non-Teflon) to the clutch face-plate.
Wipe off excess oil, reassemble clutch.
2. Replace the Feed Clutch (AX210037).
PRODUCTION COUNTERMEASURE:
The following measures have been taken to prevent the formation of rust on the Feed Clutches during and
after the manufacturing process:
1. The material used in the washing process has been changed from water to oil.
2. To prevent perspiration from contacting the clutch, rubber gloves are now used.
3. While the clutches are in inventory, they are now placed in plastic boxes and covered with a rust
preventative paper.
4. Rust preventative paper has been placed between the clutch housing and the disk.
UNITS AFFECTED:
The preventative measures described above have been implemented since the December, 1994 clutch
production run.
