2-sided Printing
This printer is equipped with a function that can perform automatic 2-sided printing.
Plain paper and heavy paper (90 to 120 g/m
2
) at sizes of A4, Legal, and Letter can
be used for automatic 2-sided printing.
By using the multi-purpose tray, you can perform manual 2-sided printing (printing
the other side of previously printed paper) on paper unavailable for automatic
2-sided printing.
IMPORTANT
•
You cannot perform automatic 2-sided printing on heavy paper (121 to 163 g/m
2
),
transparencies, labels, and envelopes.
•
When automatic 2-sided printing is specified, and a job with odd number of pages is
printed, the printing surface of the last page are as follows according to the setting for
ALT.METHOD (See p. 6-23) or the paper source.
- When printing from the paper cassette
If ALT.METHOD is set to ON, the printer prints on the underside of the loaded paper.
If ALT.METHOD is set to OFF, the printer prints on the upper side of the loaded paper.
- When printing from the multi-purpose tray.
If ALT.METHOD is set to ON, the printer prints on the upper side of the loaded paper.
If ALT.METHOD is set to OFF, the printer prints on the underside of the loaded paper.
•
Do not touch the paper during automatic 2-sided printing until it is completely output to
the face-down output tray. In automatic 2-sided printing, the paper is partially output once
after printed on its surface and is fed again to be printed on its reverse side.
•
Be sure to close the output selection cover before performing automatic 2-sided printing.
•
When performing automatic 2-sided printing, be sure to confirm that the paper size
switch lever is set to the appropriate position. If the lever is not set to the appropriate
position, this may result in misfeeds or paper jams. For details on the procedure for
setting the paper size switch lever, see "Setting the Paper Size Switch Lever," on p. 4-49.
NOTE
On automatic 2-sided printing, the reverse side of the paper is printed first, therefore the
paper should be loaded in the opposite orientation to that for 1-sided printing. If printing
on such paper with letterheads, in which faces and directional orientations are specified,
see "Paper Loading Orientation" (p. 4-51) and load the paper in the proper orientation.
