Tear-off Position
By moving the perforations in continuous forms close to the tear
bar, you can separate the forms more easily. To adjust the tear
position, see “Adjusting the Tear-off Position” on page 1-79.
Load Position
By using the operator panel, you can adjust the load position.
To adjust the load position, see “Adjusting the Load Position” on
page 1-81.
Print Alignment
This adjustment can affect the character formation and dot
mixing on those characters that are printed with two passes of
the print mechanism. To adjust the print alignment, see
“Adjusting the Print Alignment” on page 1-81.
Adjusting the Tractor Tension
The tractor tension adjustment controls the amount of buckle that the
forms have when they are loaded in the printer. Since the left tractor
does not move, you make this adjustment by moving the right tractor.
The ideal adjustment is to center the right and left paper holes of the
forms on the tractor pins without stretching or tearing the holes.
To adjust the tractor tension on the F2 forms device, follow these
steps:
1. Feed several forms through the printer.
2. Observe the left and right paper holes of the forms:
If the paper holes are stretched or torn on the outside edges,
the tractor tension is too tight (not enough buckle in the
forms).
If the forms twist or wrinkle as they move through the printer,
the tractor tension is too loose (too much buckle in the
forms).
