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 paper and specialty media designed according to
the guidelines specified under "Dimensions" on page 9. If specialty 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 x 5‑inch index cards, Lexmark offers a variety of special media tray and drawer
options.

Card stock and label guidelines
You can use many labels designed for laser printers with your Optra S printer. When printing on labels, use the printer
operator panel to set the Paper Type to Labels in the Paper Menu. For vinyl and other heavy labels, set the Labels
Weight (under the Paper Weight menu) to Heavy, and set the Labels Texture (under the Paper Texture menu) to Smooth.
Do not load labels together with paper or transparencies in the same paper tray. Combining print materials can cause
feeding problems.
The information in the specification tables is intended to convey general guidelines for tray and drawer selection. The
material type, rigidity, sizing, perforations, die-cuts, and surface influence the performance reliability.
The duplex option supports all paper weights and types that the printer supports, except for transparencies and
envelopes. Duplexing of specially designed labels is supported in the Optra S1855 printer.
You may notice skew or print registration problems if you feed materials over 135 g/m
or the optional 250‑sheet drawer. You may notice similar problems if you feed materials over 176 g/m
250‑sheet tray or the optional 500‑sheet drawer.
When feeding labels, the number of labels per sheet can affect registration more than basis weight. Typically, the more
labels per sheet, the better the registration.
Ordering special supplies for label printing
Labels are one of the most difficult print materials for laser printers to handle. To optimize printer performance, use
the special label fuser cleaner for printers dedicated to label printing.
