Lexmark C520, C522, C524
Pick roller technology
The Lexmark C520, C522, and C524 paper feeding mechanism uses advanced technology that enhances feeding
reliability. The Lexmark C520, C522, and C524 trays reliably feed all supported media.
The Lexmark C520, C522, and C524 uses an auto compensator to pick the media rather than the corner buckler system
used by earlier printer models.
The Lexmark C760 and C762 trays have two rollers that touch the media in two places (see Figure 14 on page 76). 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—1.05 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.
