Straight-through output path
Use the straight-through output path when printing envelopes, transparencies, heavy media, or any
media that tends to curl when printed. If you open the straight-through output door before printing media
from tray 1, tray 2, or optional tray 3, the media exits the printer through the straight-through output path.
NOTE
Printed media does not stack when you use the straight-through output path. The media
drops to the surface below unless you remove each sheet as it exits the printer.
