Standard trays and special trays
The Lexmark X644e and X646e paper feeding mechanism uses advanced technology that enhances feeding reliability.
The standard Lexmark X644e and X646e trays hold 250 or 500 sheets of bond paper and reliably feed all media tested
according to the guidelines specified under “Dimensions” on page 9.
For those difficult‑to‑print sizes, such as 3 x 5‑inch index cards, Lexmark offers a variety of special media trays and
drawers.
Note: Optional 250‑sheet Universally Adjustable Trays can be used to print forms with a minimum length of 5 inches
when installed either in the integral tray location or in a 250‑sheet drawer under a 250‑sheet integral tray. Forms
less than 7 inches in length are not supported from a 400‑sheet universally adjustable tray.
