Caution Failure to follow these instructions can damage the printer.
•
Do not load the trays to capacity because labels are heavier
than paper.
•
Do not use labels that are separating from the backing sheet,
wrinkled, or damaged in any way.
•
Do not use labels that have the backing sheet exposed. (Labels
must cover the entire backing sheet with no exposed spaces.)

The adhesive backing is designed for only one pass through
the printer.

Do not print on both sides of labels.
