Pick roller technology
The Lexmark C752 uses an auto compensator to pick the media rather than the corner buckler system used by earlier
printer models.
The Lexmark C752 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.
