2-5. Paper Ejection Mechanism
To enhance paper ejection stack performance and processing speed, the paper ejection drive mechanism is
intermittently driven by the electromagnetic clutch. To improve operability, the movement of the stacker roller has
been made automatic.
2-5-1. Replacing the stacker belt
Take note of the following points when replacing the belt.
Belt front/back : The green side is the front.
Rotating direction of the belt: The rotating direction is indicated by an arrow on the belt back (black side).
2-5-2. Adjusting the tension of the stacker belt
Perform the following check and adjustment if the stacker belt slips while rotating.
Normally, the belt slips due to the change in the frictional coefficient between the stacker plate and belt back from the
load of the stacker roller.
q If the belt slips with the stacker roller and belt not
contacting (the stacker roller is raised), perform step
w.
If the belt does not slip in this state, perform step e.
w Generally, the ST shaft assembly is fixed at the
topmost position of the frame long hole. This state is
the recommended stretch rate of the belt. (Stretch
rate: 4%)
If the belt slips, loosen the screw fixing the ST shaft
assembly, and adjust the tension of the belt by
moving the assembly.
The adjusting range is within 2 mm (0.08").
e The area where the stacker plate and belt back
contact each other is pasted with a Teflon tape to
reduce the frictional coefficient. The belt may start to
slip when the effects of the tape drop. In such cases,
paste a new tape.
