fective beyond that. Take care
not to back out the screw too
far as it could fall loose inside
the frame.
5.2 Folder Belt
Tension
Warning! Disconnect the
power cord before making
this adjustment.
Remove right side cover, hand-
wheel, circuit breaker, speed control knob and nut. Check belt
tension on motor timing belt. It should deflect approximately
1/4" - 3/8". If loose, adjust by loosening the four motor screws
and relocate the motor. Reassemble side components.
5.3 Paper Guide Adjustment
Place the paper to be used on the feed table, between the paper
guides. The guides should be placed so that the center of the feed
roller is aligned approximately with the center of the paper. The
guides should be adjusted to allow the paper to move freely
down the feed table without angling to one side or the other.
Paper to be fed into the machine should always be jogged and
aligned to enter the fold tables squarely. The paper guides can be
adjusted to the proper width by loosening the adjustment screw
located underneath the feed table and sliding the rod clamps
sideways. The paper guides are mounted to the feed table with
an adjustment bar. This adjustment bar is fixed on one end and is
adjustable with a 1/4 - 20 lock screw on the other end. To adjust,
place a square against the folding rollers and one paper guide,
loosen the lock screw and move the shaft to square the guide to
the rollers. Lock the screw tightly in place.
