tightening the screw.

Spring Adjustment


Two holes [F] are provided on each pressure arm for the springs.

Normally the springs should be attached to the lower holes.

Attaching the springs to the upper holes exerts less pressure on the hot roller. Attach the
springs to the upper holes only for especially thin paper.
