2 TROUBLESHOOTING
Check the following troubleshooting list before requesting service as many problems can be fixed by the user. If you
are unable to solve the problem by checking the list, turn off the power switch, unplug the power cord.
Problems related to general use of the machine are described below. For problems related to the copy function, see
page 6-3. For problems related to document filing, see page 7-28. For fax, printer, and network scanner problems,
see the manuals for those functions. For peripheral device problems, see the explanation of the device.
If the message CALL FOR SERVICE. CODE:**-**
(Note) appears in the touch panel, turn off the power switch, wait
about 10 seconds, and then turn the power switch back on. If the message still appears after turning the power
switch off and on several times, it is likely that a failure has occurred that requires service. In this event, stop using
the machine, unplug the power cord, and contact your Sharp dealer.
Note: Letters and numbers appear in **-**. When you contact your Sharp dealer, please tell your dealer what
letters and numbers appear.

frequently.Is paper other than SHARP-
recommended paper being used?Use SHARP-recommended paper. (Page 2-16
)
Paper curled or damp?Do not use curled or crimped paper. If you will
not use the paper for a long time, remove the
paper from the tray and store it in the wrapper in
a cool and dark location so that it will not absorb
moisture.
Is the paper curled and does it
frequently misfeed in the finisher or
saddle stitch finisher?Paper may be curled when output depending on
the paper type and quality.
In some cases turning the paper over in the tray
will reduce misfeeding due to curling.

DUPLEX MODULE
If a duplex module is installed, printing onto both sides of paper can be performed.
Two types of duplex modules are available: duplex module/bypass tray and duplex module. The descriptions in this
manual are for the duplex module/bypass tray. For information on misfeed removal for these modules, see page
2-19.
Part names
Specifications
*1For paper size and paper weight for the bypass tray, see Specifications of paper trays (types and sizes of
applicable papers for trays) on page 2-3.

Specifications are subject to change for improvement without notice.
NOTES

Do not press down on the bypass tray or the exit tray.

The duplex module requires the installation of other peripheral devices in order to be functional and cannot be
installed together with some other devices. The table on page 8-4 shows the configurations which are
compatible.

Loading paper in the bypass tray
The bypass tray can be used for plain paper and special paper including labels. Up to 100 sheets of standard paper
can be set. For paper types that can be used in the bypass tray, refer to page 2-3.
1Open the bypass tray.
When setting A3, B4,
11x 17, 8-1/2 x 14 or
8-1/2 x 13 paper, be
sure to extend the
bypass tray extension.
If the bypass tray
extension is not pulled
all the way out the size of
the loaded paper will not
be correctly displayed.
2Set the bypass tray paper guides to the
width of the paper to be used.
3Insert the paper all the way into the bypass
tray.
Set the paper face
down. If there is a
clearance between the
paper and the paper
guides, the paper may
not be fed correctly.
Adjust the guides so that
they contact the edges
of the paper.
4Set the type and size of the loaded paper.
When the paper system is changed from the inch
system to the AB system or vise versa or when the
paper type is changed, the paper type must be
designated. For setting the paper type and paper
size, see page 2-5.
5Loading paper in the bypass tray is now
complete.
NOTE
If the paper type or size is changed, be sure to enter the paper type and size as in step 4.
Bypass tray extension
NOTES
When using A5 paper, 5-1/2 x 8-1/2 paper or
postcards, be sure to load them with their shorter edge
into the feed slot as shown in the illustration.

When loading plain paper other than SHARP standard paper,
special media other than postcards, SHARP-recommended
transparency film, or paper to be printed on the back, the
paper must be loaded one sheet at a time. Loading more than
one sheet at a time will cause misfeeds.
When adding paper, remove any paper remaining in
the tray, combine it with the paper to be added, and
reload as a single stack.
Do not use paper that has already been printed on by
a plain paper fax machine or a laser printer. This may
cause printed images to become dirty.
Do not use paper that has already been printed on by
a thermal transfer or inkjet printer. In particular, paper
that has been printed on by a thermal transfer printer
(such as a word processor that uses a cassette) may
cause missing characters and smudges.
When printing on transparency film, be sure to remove
each sheet as it exits the machine. Allowing sheets to
stack in the output tray may cause curling.
Please use SHARP-recommended transparency film.
Place the film in the bypass tray so that it is oriented
vertically with the label side face up. If the label side is
placed face down, smudging may result.

When loading multiple sheets of transparency film in the bypass
tray, be sure to fan the sheets several times before loading.

3 MAIL-BIN STACKER
The mail-bin stacker has 7 mail bins which can each be designated to receive printed output from a user or a group
of users .
Output paper in the copy mode and the fax mode will be delivered to the top tray of the stacker separated from printed
output. (Printed output can also be delivered to the top tray.)
Part names
Specifications
Specifications are subject to change for improvement without notice.
NOTES

Do not put pressure on the mail-bin stacker, particularly on the top tray and mail bins.

Do not place anything on the top cover. Doing so will interfere with the machine’s paper handling during duplex
printing.

The top tray and each mail bin are extendable. To print onto large paper (A3, B4, 11 x 17, 8-1/2 x 14 or  8-1/2
x 13), extend the tray.

The mail-bin stacker requires the installation of other peripheral devices in order to be functional and cannot be
installed together with some other devices. The table on page 8-4 shows the configurations which are
compatible.
