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 20 lb (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 6” on
page 39). 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 9 for more information.
Media Specifications
Labels Thickness: 0.102 to 0.305 mm (0.004 to 0.012 in.)
