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 1-48.
Adjusting the Tractor Tension
The tractor tension adjustment controls the amount of buckle 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 F1 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).
3. Adjust the right tractor as necessary:
Unlock and move the tractor toward the left side of the
printer to loosen the tension on the forms.
Unlock and move the tractor toward the right side of the
printer to tighten the tension on the forms.
