to put tension on the belt. This belt should
deflect approximately 1/16” at the center of belt

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.
