Lexmark 25C0010 - X 500n Color Laser Manual page 28

The two materials must be thin enough for the sheet to lie flat in the paper tray. Orient the form in the tray so that
the pressure-sensitive area feeds into the printer first. The form should have no adhesive exposed in the overlay area
or anywhere along the front or back of the form. We recommend designing a non-adhesive strip with a minimum
width of 1 mm (0.04 in.) along the edges of the overlay.
To help prevent material from slipping in the fuser, we recommend knurling, which roughens up the exposed silicon
area at the glue joint.
The face sheet of a dual web form is usually a paper pressure-sensitive product; therefore, the guidelines for paper
labels are applicable to dual web forms.
The following diagram shows the recommended dual web form design. The non-print area may vary, depending on
the printer model.

Vinyl and polyester labels
Vinyl labels work well within specified design parameters. Vinyls are heat-sensitive, so the liners need to be thick
enough to absorb excess heat and prevent melting. A total strip matrix may cause adhesive contamination. Thin
liners or weak pull strength may lead to labels peeling off the form inside the printer, which will require printer
servicing. For more information on recommended label designs, see "Label design guidelines" on page 23.
