Adjustment
1. Loosen the 2 screws that mount the tension lever.
2. Use the push-pull scale to push on the lever to tension the belt to 0.55 to 0.75 kg (1.2 - 1.6 lb).
3. Tighten the front screw first, then the rear screw.
Automatic Forms Thickness Adjustment (AFTA)
The Automatic Forms Thickness Adjustment (AFTA) allows the printer to maintain a consistent distance between
the printhead and the face of the forms. Maintaining this distance (or gap) allows the printer to produce correct
print darkness, properly feed forms, and sustain printhead-drive operation. There are two service check and
adjustment procedures one may use with AFTA. There is a procedure that is relatively short and simple to
perform: the Quick AFTA Service Check and Adjustment, and then there is the “Standard AFTA Service Check and
Adjustment” on page 285. It is recommended that one perform the
″
Quick
″
procedure first; if the results are not
favorable, proceed then to the
″
Standard
″
procedure.
Attention: Do not attempt any adjustments, loosen any screws, or perform any steps until instructed to do so.
