Timing Belt Tension
Refer to Figure 3-18 for this adjustment procedure.
1. Loosen the two screws (A) holding the belt tension adjustment levers (B) on both sides of the bill acceptor
transport.
2. Make sure that the adjustment levers, adjusting roller, and shaft move freely.
3. Each belt should be adjusted such that it is as loose as possible, but tight enough that it will not “jump” the drive
pulleys when the transport is under a heavy load such as reversing a badly wrinkled bill. If a more precise
adjustment is desired, perform the following step:
A. Apply 75 grams of perpendicular force to both belt tension adjustment levers at the same time and then
tighten all four screws.
AB
Apply 75 grams of force at this poi
in the direction shown.
