The Accessories Tab includes the settings for configuring the
printer driver for the size of paper loaded in each paper source. This

Paper Source Setting
To configure the paper size for each paper source, highlight the
source in the Paper Source Setting list. Select the Paper Size from
the pull-down box and click Update. When Auto Select (default
paper source) is set in the Basic tab of the printer driver (see Basic

in the printer driver.
Default Source
The Default Source allows you to choose the paper source that will
be used when the paper size of the document being sent does not
match the Paper Source settings.

In order to use the optional 2nd paper
tray, you must install the option in the
driver. Highlight the model number
from the Available Options list and
click Add. The optional tray will then
be listed in the Installed box, Paper
Source Setting list and the screen
illustration will display the 2nd tray.
