Lexmark C750
Standard trays and special media trays
The Lexmark C750 paper feeding mechanism uses advanced technology that enhances feeding reliability. The Lexmark
C750 trays, which hold approximately 500 sheets of 75 g/m
2
bond paper, reliably feed all supported media.
Pick roller technology
Like the Optra S and Optra T, the Lexmark C750 printer uses an auto compensator to pick the media rather than the corner
buckler system used by earlier printer models.
The Lexmark C750 trays have two rollers that touch the media in two places (see
Figure 13 on page 72
). 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.
