together.
There will be an
extra fold in form
near the correct
fold location.
The form which
caused the jam
will be folded
crooked.

fold plate settings. The location of perforations on forms may fluctuates by
as much as 1/16” in either direction. Because of this fluctuation, it is
sometimes necessary to fine tune the placement of the paper stop on one
of the fold plates.
The first step is to identify which fold plate is misaligned. Watch the form as
it is fed into the machine, and then compare it to the finished form. If you’re
having trouble visualizing which fold is off, refer to the section
Loading the
Feed Table
above.
Once you’ve identified which fold plate needs to be adjusted, remove it
from the

. If the fold is crooked, check to make sure that the
paper stop is parallel to the front edge of the fold plate. Check that the
indicator points on the paper stop indicate the same reading on the two
scales of the fold plate. Also check the feed table to make sure that paper

perforation, adjust the paper stop by the amount that the fold is off. If the
