Tray Select as the tray setting is submitted and the tray runs out of paper.
Enabled (=0: Default):
Limitless Paper Feeding is applied to the Bypass Tray.
If a tray other than the Bypass Tray matches the job's paper size and type but has run out of paper,
printing will occur from the Bypass Tray.
Disabled (=1):
Limitless Paper Feeding is not applied to the Bypass Tray.
If a tray other than the Bypass Tray matches the job's paper size and type but has run out of paper,
printing will stop and an alert will appear on the LCD screen, stating that the tray has run out of paper.
This prevents unexpected use of the Bypass Tray.
Limitations when this BitSwitch is set to "1":
 The "Paper Tray Priority: Printer" setting must be configured to a tray other than the Bypass Tray.

Jobs that contain more than one paper size cannot be printed.
