Lexmark CX310 Quick Reference

Loading the 250‑sheet tray
The printer has a 250-sheet tray (Tray 1) with an integrated manual
feeder. The 250-sheet tray and the 650-sheet duo tray support the
same paper sizes and types and are loaded in the same way.
CAUTION—POTENTIAL INJURY: To reduce the risk of
equipment instability, load each tray separately. Keep all other
trays closed until needed.
1 Pull out the tray completely.
Note: Do not remove trays while a job is printing or while Busy
appears on the display. Doing so may cause a jam.
2 If the paper is longer than letter‑size paper, then squeeze and then
slide the length guide at the back of the tray to extend it.
3 Squeeze, and then slide the length guide tab to the correct position
for the size of the paper being loaded.
Note: Use the paper size indicators on the bottom of the tray to
help position the guide.
4 Squeeze, and then slide the width guide tab to the correct position
for the size of the paper being loaded.
Note: Use the paper size indicators on the bottom of the tray to
help position the guides.
5 Flex the sheets back and forth to loosen them, and then fan them.
Do not fold or crease the paper. Straighten the edges on a level
surface.
