CONTROLLER FUNCTIONS 31 May, 1999
Tray Lock
If Tray Lock is enabled for a tray, the controller does not use the "locked" tray in the
tray search process. If a tray has, for example, coloured A4 size paper for fax
prints, enable tray lock for that tray so that the controller does not select the tray for
printing.
If the printer driver selects a "locked" tray, the controller uses the tray for printing
only when the specified paper size matches the actual paper size in the tray.
By-pass Tray
The by-pass tray is not part of the automatic tray search. To print from the by-pass
tray, the user has to select the by-pass tray. Even if the by-pass tray is empty, the
controller will not switch to another tray; the message on the LCD asks the user to
add paper to the by-pass tray.
NOTE: Collation is disabled when the by-pass tray is selected.
Paper Size Mismatch
When the controller could not find the specified paper size in any of the trays, the
machine displays an error message, e.g., "Load 8 ½ x 11".
Then the user can either load the requested paper size in a tray or select another
tray, e.g., a tray that contains A4 size paper, by pressing the "Form Feed" key.
The controller will print the job if the specified paper size is detected in a tray, or if
the user presses the Enter key after selecting a tray.
2.2.3 OUTPUT TRAY SELECTION
Output Tray Priority in the System User Tools specifies the default paper output
tray for each application. If a print job does not specify an output tray or the driver
specifies the Default Tray, the default tray is used.
If the driver specifies an output tray, this overrides the default tray setting in the
user tools.
If the option one-bin tray is selected but it has an error, the standard output tray is
used.
