2. Basic Setup
Arrangement: Only use labels with no exposed backing between them. 
Labels can peel off sheets that have spaces between the labels, causing 
serious jams.
Curl: Must lie flat with no more than 13 mm of curl in any direction.
Condition: Do not use labels with wrinkles, bubbles, or other 
indications of separation.
Make sure that there is no exposed adhesive material between labels. 
Exposed areas can cause labels to peel off during printing, which can cause 
paper jams. Exposed adhesive can also cause damage to machine 
Do not run a sheet of labels through the machine more than once. The 
adhesive backing is designed for only a single pass through the machine.
Do not use labels that are separating from the backing sheet or are wrinkled, 
bubbled, or otherwise damaged.
