Lexmark X642e
Pick roller technology
The Lexmark X642e printer uses an auto compensator to pick the media from the tray. The auto compensator has two
rollers that touch the media (see
Figure 17 on page 103
). Avoid placing deep perforations in these areas since the media
may nest, causing multiple sheet feeds. Perforations that could cause nesting and tenting should fall outside the 0.3—0.79
in. area on the leading edge of the media. (This is different from the 0.50 in. we recommend leaving at the top of the form
for printers with a corner buckler system.) You may want to use micro-perfs to avoid nesting problems. See Perforations
and die-cuts on page 8 for more information.

Label printing
Labels are one of the most difficult print materials for laser printers. A special fuser cleaner should be used for label
applications to optimize feed reliability. See your printer documentation for information on ordering additional label fuser
cleaners.
When printing on labels:
•
Set the Paper Type to Labels in the Paper Menu. For vinyl and other heavy labels, set the Paper Type to Vinyl
Labels.
Note:
When Paper Type is set to Vinyl Labels, the printer reduces the printing speed to ensure acceptable
printing.
•
Do not load labels together with paper or transparencies in the same paper tray. Combining print materials can
cause feeding problems.
•
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a paper jam. Adhesive
material may contaminate your printer. It could also void your printer and cartridge warranties.
