Apple ColorLaserWriter 12/600PS - Manual (Page 176)

Designating the 250-sheet feeder as the preferred paper source
You can tell the printer to use the optional feeder as the preferred paper
source. If you do, and you choose Auto Select in the Print dialog box, the
printer looks first in the 250-sheet feeder for paper. If it’s out of paper, the
printer looks in the standard cassette.
For more information about how the printer uses paper sources, see
“Setting Paper-Handling Options” in Chapter 2 if you have a Macintosh,
or in Chapter 3 if you have a Windows computer.
