Pick Roller Technology
The Lexmark T520 and T522 printers use an auto compensator to pick the media rather than the corner buckler system
used by earlier printer models.
The Lexmark T520 and T522 trays have two rollers that touch the media in two places (see
Figure 15 on page 93
). 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 0.31—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.

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:
•
Using the printer operator panel, set the Paper Type to Labels in the Paper Menu. For vinyl and other heavy
labels, set the Labels Weight (under the Paper Weight menu) to Heavy, and set the Labels Texture (under the
Paper Texture menu) to Smooth.
•
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.
When feeding labels, the number of labels per sheet can affect registration more than basis weight. Typically, the more
labels per sheet, the better the registration.
