2-9 Operation
Figure 2-5. Paper Adjustment Controls - Pedestal Model
Forms Thickness Adjustment Lever - The Forms Thickness Adjustment Lever, shown in
Figure 2-6, controls the platen gap. Raising the lever opens the platen and lowering the lever
closes the platen to adjust for various paper thicknesses. The scale indicates approximate posiĆ
tioning to correspond with paper thickness (1 to 6 part forms). Generally, set the lever for a
slight friction on the paper as it moves past the hammer bank. If the Forms Thickness AdjustĆ
ment Lever is set incorrectly, the print hammer flight timing can be upset, resulting in waviness
of vertical lines (called poor phasing). When fully raised, the platen is open to allow paper loadĆ
ing and ribbon replacement; a platen open message is shown on the display. After lowering the
lever to the appropriate operating position, press CLEAR FAULT on the Control Panel to
clear the platen open condition.
