2. Adjust the rear paper support (4) to the size of paper you are using by gripping the
lug, tilting and sliding the support forwards or backwards as necessary.
3. Adjust the paper guides (5) by gripping the lug and moving it backwards or forwards
to match the size of the paper used. It is important to adjust the paper guides
correctly to ensure that the paper is not skewed in the print process. Paper jams
may occur if this operation is not carried out correctly.
4. Replace the tray in the printer.
Face up and face down printing
For face down printing, make sure the Rear stacker is closed (the paper exits from the top
of the printer). The Output Stacker on the top of the printer stacks printed pages face down,
capacity 150 sheets of weight 80g/m². Pages printed in reading order (page 1 first) will be
sorted in reading order (last page on top, facing down).
The face up stacker should be opened and the tray extension pulled out when required for
use. (With the face up stacker either opened or closed, the driver setting of face down will
successfully direct prints to the face down stacker.)
The face up stacker can hold up to 100 sheets 80g/m² standard paper.
Always use this stacker in conjunction with the Manual Feed Tray, Multi Purpose Tray or for
heavyweight stocks to reduce the possibility of paper jams.
See “Paper and tray information” on page 76.
Automatic feed sequence
With no optional feed trays installed, the Autotray function in the Print Menu is set by
default to ON and the Tray sequence function is set to DOWN. In this way, if a tray runs
out of paper, automatic feed will take place in the order Tray 1, Tray 2 (if fitted), Multi
Purpose Tray or the Manual Feed Tray, provided that these trays are set up for identical
media. Also, configure the media size and media weight for the respective trays in the
operator panel or Configuration tool, depending on your printer model.
NOTE
If you have the optional second paper tray (Tray 2) and you are printing from
the first (upper) tray (Tray 1), you can pull out the second (lower) tray to
reload it. However, if printing from the second (lower) tray, do not pull out the
first (upper) tray as this will result in a paper jam.
