4 Pay attention to the paper limit mark on both inside walls
of the paper input tray. Paper overloading may cause
paper jams.
5 Insert and slide the paper input tray back into the
machine.
N OTE : After you load paper, you need to set up your machine
for the paper type and size you loaded. See page 3.6 for
copying, or the Software Section for PC-printing. The
settings made from the printer driver override the settings on
the control panel.
Changing the size of the paper in the paper
input tray
To load longer sizes of paper, such as Legal-sized paper, you
need to adjust the paper guides to extend the paper input tray.
1 After pressing and unlatching the guide lock, slide the
paper length guide out completely to extend the paper
input tray to its full length.
2 After inserting paper into the paper input tray, squeeze the
front paper length guide and slide it until it lightly touches
the end of the paper stack.
For paper smaller than Letter size, adjust the front paper
length guide so that it lightly touches the paper stack.
