38. Slide the rewind assembly toward the rear of the printer until the belt tension is tight.
Extend the wrench through the access holes in the backing take-up pulley assembly, and
tighten the three screws.

slide the assembly toward the rear of the printer until belt tension is tight. Tighten the
screw to secure the idler pulley.
40. Hook a spring scale at the midpoint of the lower section of the belt and pull up. The belt
should deflect 0.25 inches (6 mm) with a tension of 2000 grams (4.5 lbs.). Readjust the
belt tension by changing the position of the idler pulley.
