9. Slide the film feed belt take-up shaft to the belt
to put tension on the belt. This belt should
deflect approximately 1/16” at the center of belt
span for proper tension. (Note: Repeat this
procedure on the platen roller belt take-up shaft
if the SX is equipped with a printer.)
10. Reinstall the drive motor belt and adjust the
belt to proper tension. This belt should deflect
about 3/32” when tightened correctly.
11. Replace the pulley guard and the outside frame
guard removed in step 1, and close the cradle
cover.

showing signs of wear, such as cracking or
