In Peel-Off Mode, proper media tracking is critical. The rewind power roller automatically
turns along with the movement of media to ensure continuous rewind of the liner. When
adjusting this roller, the operating position may vary due to the type, width, and thickness
of the liner.
Before performing this adjustment, review the procedures in
“Media Loading” on page 2-6. Ensure minimal sideways movement during the printing
process by positioning the left edge of the liner even with the edge guide mark on the
tear-off/peel-off plate. Position the outer media guides against the outside edge of the
media, but no so tight as to bind the material.
When the rewind power roller is properly adjusted, the liner should have even tension
across its entire width and be wrapped snugly around all guides and rollers. If the tension
is not even, the liner may slide (walk) to the left or the right as printing occurs. This can
cause print registration problems on the labels.
Adjusting the Rewind Power Roller
1. Refer to Figure 2-18. Locate the power roller adjustment screw.
2. Use a screwdriver to turn the power roller adjustment screw counterclockwise to
increase the tension on the right side of the rewind power roller. Turn the power
roller adjustment screw clockwise to decrease the tension on the right side of the
rewind power roller.
3. Use the Feed Key Self Test to print several labels to ensure tracking is maintained
and tension on both edges of the liner remains consistent. Remember to remove
each label as it is automatically peeled away from the liner.
By turning the power roller adjustment screw clockwise, the tension in the right side
decreases. Adjust screw until the tension is equal on the left and right sides of the
rewind power roller and the liner tracking is maintained.
Note • The rewind power roller is present only on printers with the Peel-Off Option.
This roller is pre-set during manufacture for proper operation with most applications.
Adjust this roller only when necessary.
Note • Balancing the tension increases the reliability of the printer to provide properly
printed labels by preventing the liner from walking.
Note • The adjustment changes the position of the right end of the rewind power roller
only. The left end remains stationary.
Example 1 • Figure 2-18 illustrates an improperly adjusted rewind power roller. On
the left side, the liner is not contacting the rewind power roller. This is because the liner
has more tension on the right edge than on the left.
