Backing Rewind Power Roller Adjustment

(PEEL-OFF OPTION REQUIRED)

NOTE: This roller is only present on printers with the Peel-Off option. Zebra presets this roller during manufacture for proper operation with most applications. Only adjust this roller when necessary.

In the Peel-Off mode, proper media tracking is critical. The rewind power roller automatically turns along with the movement of media, to insure continuous rewind of the label backing material. When adjusting this roller, the operating position may vary due to the type, width, and thickness of the backing material.

Before performing this adjustment, review the media loading procedure in Getting Ready to Print. Insure minimal sideways movement during the printing process by positioning the left edge of the label backing even with the edge guide mark on the tear-off/peel-off plate. Position the media guides against the outside (right) edge of the media, but not so tight as to bind the material.

When the power roller is properly adjusted, the backing material should have even tension across its entire width and be wrapped snugly around all guides and rollers. If the tension is not even, the media/backing material may slide (walk) to the left or to the right as printing occurs. This can cause print registration problems on the labels.
