The following table indicates the paper sizes each tray supports.
Paper source specifications for all media

250-sheet tray

Multipurpose feeder
If you load paper that is narrower than 148 mm (5.83 in.) in the multipurpose feeder (for example, 3x5 inch index cards),
set the MP Feeder Size menu item to Universal.
See your printer documentation for specifications on tray capacities.
Standard trays and special media trays
The Optra S paper feeding mechanism uses advanced technology that enhances feeding reliability. The standard Optra S
tray, which holds 250 or 500 sheets of bond paper, reliably feeds all media designed according to the guidelines specified
under Dimensions on page 7. If media does not conform to these guidelines, we recommend using the 250-sheet special
media tray option, P/N 43H5410, to prevent double sheet feeds.
For those difficult-to-print sizes, such as 3-inch x 5-inch index cards, Lexmark offers a variety of special media tray and
drawer options.

Pick roller technology
The Optra S family of printers uses a different type of pick roller than earlier Optra models. Earlier models used a corner
buckler system to separate the sheets of media; the current Optra S uses an auto compensator. Media no longer has to be
placed under a corner buckler.
The Optra S trays have two rollers that touch the media in two places (see Figure 18 on page 127). 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.
