2.2 CONTROLLER FUNCTIONS
2.2.1 PAPER SIZE DETECTION AND SELECTION
The controller uses the paper sizes detected by the print engine for trays 1, 2 and
3. For the by-pass tray, the user has to specify a paper size using the Job Control
menu in the Printer User Tools. Refer to section 1.1.2 for details on supported
paper sizes.
When the printer controller receives a print job, the controller uses the paper size
specified in the PJL, PCL, or PS commands for printing.
2.2.2 PAPER SOURCE SELECTION
Auto Tray Select
The controller searches for the specified paper size, starting from Tray 1, and uses
the first tray that has the specified paper size. If the selected tray is pulled out or
paper runs out during printing, the controller searches for another tray with the
specific paper size and if found, automatically switches to it. If the controller cannot
find another paper tray with the specified paper size, printing stops and the LCD
displays the message "Add Paper to Tray 1".
Manual Tray Select
When the printer driver specifies a tray, the selected tray becomes the first tray
checked at the start of the tray search. If the selected tray does not have the size of
paper specified by the driver, the controller searches the other trays for the same
paper size.
NOTE: Tray Priority in the Job Control menu does not specify the start of the tray
search, but specifies the paper size in the selected tray as the default
paper size.
