Pick Roller Technology
Like the Optra S and Optra T, the Lexmark T52x, T62x, and T63x family of printers use an auto
compensator to pick the media rather than the corner buckler system used by earlier printer models.
The Lexmark T620, T622 trays have two rollers that touch the media in two places (see “Figure 9” on
page 69). 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 9 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. Refer to 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.
