Printer Service Mode
1001 Bit Switch
When the Bypass Tray is the target of the Auto Tray Select and Any
Size/Type is configured for the Tray Setting Priority setting of the Bypass
Tray, this BitSwitch can switch the behavior whether or not Limitless Paper
Feeding is applied to the Bypass Tray.* The default is Enabled (=0).
*Limitless Paper Feeding will try a matching tray of the next highest priority
if a job specified to Auto 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.
bit 3 Not used
bit 4 Add "Apply Auto Paper Select" is the
condition that decides if the device's
paper size or paper type should be
overwritten.
If this BitSwitch is set to "1" (enabled), the "Apply Auto Paper Select"
setting will decide if the paper size or paper type that is specified in the
device settings should be overwritten by the job's commands when "Tray
Setting Priority" is set to "Driver/Command" or "Any Type".
- Apply Auto Paper Select = OFF: Overwritten (priority is given to the job's
commands)
- Apply Auto Paper Select = ON: Not overwritten (priority is given to the
device settings)
