Apple ColorLaserWriter 12/600PS - Manual (Page 128)

Conserving energy
The Color LaserWriter 12/600 PS automatically reduces its power
consumption after 60 minutes of inactivity. You can lengthen or shorten the
time that the printer remains idle before it reduces its power consumption.
Once the printer turns down its power, it will need to warm up again before
printing the next document. Network users may experience a delay of up to 3
minutes in printing.
1 Open the Printer Preferences category.
You see a list of preferences.
2 Open the Energy Saving Delay category.
3 In the panel that appears, select a delay time from the list box.
4 To send the setting to the printer, click Send.
Setting paper-handling options
When the printer runs out of paper in one tray, it can automatically switch
and use paper from the paper cassette or multipurpose tray. By using
automatic tray switching between the 250-sheet paper cassette and the 100-
sheet multipurpose tray, you can print 350 sheets without reloading paper.
You can also tell the printer what size paper is in the multipurpose tray. Then,
if you print a job that uses a different size paper, the printer will not use this
tray.
1 Open the Job Defaults category.
You see a list of preferences.
2 Open the Paper Handling category.
3 In the panel that appears, click the checkbox to turn Automatic Tray Switching on or off.
An X in the checkbox means the printer looks for paper in the multipurpose
tray when other paper sources are empty.
