auxiliary tray during operation.

the envelope size you loaded in the auxiliary tray (see "Defining the
Auxiliary Tray Paper Size" on page 64). Values specified in print jobs
override values you set at the printer. To select the auxiliary tray as the
default source tray, set SOURCE to AUXTRAY in the Paper Menu (see
"Selecting The Default Input Tray" on page 63).
Loading Custom Paper and Envelopes into the Auxiliary Tray
You can use the auxiliary tray to print any paper or envelope size that falls
within the following range:
Minimum:
3.5 x 5.8 in
88 x 148 mm
Maximum:
13 x 20 in
330 x 508 mm
To print a custom form, do the following:
1. Set the AUXSIZE item in the Paper Menu to UNIV for paper or UNI-ENV
for envelopes.
2. Make sure your print application sets the proper margins. The printer does
not reflow data to fit the paper or envelope you load in the auxiliary tray.

For example, if your custom form is 230 mm wide, calculate the side
margins as follows:
