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.

Card stock and label guidelines
Labels are one of the most difficult print materials for laser printers. A special fuser cleaner should be used for label
applications to optimize feed reliability. See your printer documentation for information on ordering additional label
fuser cleaners.
Printing labels on the X644e and X646e requires a special label fuser cleaner that prevents duplexing.
It is recommended that when you run vinyl labels, you install a special oil fuser cleaner, P/N 40X2665. When you order
a new label cartridge, order the X644H01A high yield return print cartridge or X644X01A extra high yield print cartridge.
It is possible to duplex certain labels that have been specifically designed for this application. To duplex labels, consult
the Lexmark "Converter Lists" to see which converters have successfully developed this type of label, and you must
install a special fuser wiper. The wax wiper that is used with the X644e and X646e is P/N 40X2666 (Cartridges designed
for duplex label printing contain two wax wipers. Change the wax wiper at the halfway point of your normal cartridge
usage to provide additional cleaning and optimize performance.)
