Adjusting the motor belt tension
1. Loosen the two screws securing the reverse motor.
2. While firmly pushing the motor to the left, retighten
the screws in the order described in the illustration.
Fully tighten the first screw before the second one.
(The belt tension will be proper even if the motor is
strongly pushed to the left.)
Caution
If the screws are tightened in a different order
from the specified one, too much tension will be
applied. (When the second screw is tightened,
the motor pulley slightly moves, applying more
tension to the timing belt. This will cause the
motor shaft to break.)
3. Loosen three screws each securing the transport
motor and original feed motor.
4. In the same way, retighten the screws as
described in the illustration.
5. Check if the tension of each timing belt is proper.
Note:
Proper tension can be obtained by following steps
2 and 4 only. At step 5, make sure the timing belts
do not slip on the pulleys when drive is applied.
