FILM FEED ROLLER DRIVE BELT
1. Ensure the film feed roller drive belt has the
proper tension. Refer to
Machine
Adjustments: Checking Belt Tension
section
to determine the correct tension.
2. Perform a visual inspection of the belt. If it is
showing signs of wear, such as cracking or
fraying, it needs to be replaced.
3. Refer to the
Machine Adjustments: Checking
Belt Tension
section to determine the correct
tension.
1. Remove the outside frame guard and the
pulley guard (Figure 3-153).
2. Loosen the belt take-up shaft to create slack in
the belt (Figure 3-154). (Note: if the model
SX
is equipped with a printer, the platen
roller belt take-up shaft must also be loosened
to give the platen roller drive belt slack.
3. Loosen the four screws that mount the film
feed drive motor and remove the belt. (See
