Turning tray switching on or off
Tray switching lets you switch automatically between the paper cassette and
the multipurpose tray (or other optional paper source) without reloading
paper when one paper source runs out of paper.
IMPORTANT If you have the same size paper in your paper cassettes and
multipurpose tray and have tray switching turned on, the printer may draw
paper from any paper source that has the correct size paper (even if you
select a specific paper source from the Print dialog box). If you want to print
from a specific paper source only, turn automatic tray switching off.
