Additional Forms Restrictions
For best results when printing, the following forms restrictions apply:
Fastening recommendations:
– Form plies must not be fastened with any staples and must
be fastened securely enough to prevent partial forms
separation.
– For the F3 forms device, multiple-part forms must be glued
only at the top edge and fastened securely enough to
prevent forms separation.
– For the F4 forms device, only top-glued or snap-out
multiple-part forms should be used.
– If crimp fasteners are used, you should consider the
following:
- Crimps should not project significantly above the surface
of the first form to avoid ribbon interference.
- Crimps should not add significantly to the total forms
thickness.
- The protruding tail of the crimp should be opposite the
direction of forms motion so that the forms motion tends
to compress and tighten the crimp. The crimp should
also be away from the surface of the forms where
printing is occurring to avoid ribbon interference.
- Excessively hard or stiff crimps can interfere with proper
ribbon and forms processing operation.
Forms stacking:
– For best stacking efficiency, the distance between folds
should be 152.4 to 317.5 mm (6 to 12.5 in.).
Feed holes should be free of chads and crimps to avoid false
form jam errors.
Forms should be strong enough to prevent tearing of feed holes.
Label forms should be tested for satisfactory forms handling,
print registration, and print quality.
Do not use forms that have started to come apart.
