.Follow the steps below to load paper into the tray.
PAPER
For best results, use only paper recommended by SHARP.
* Do not use non-standard envelopes, and envelopes that have metal clasps, plastic
snappers, string closures, windows, linings, self-adhesive, patches or synthetic
materials. Do not use envelopes that are filled with air or envelopes that have
labels or stamps attached. These will cause physical damage to the unit.
** For paper weighing from 105g/m2to 128g/m2, A4 is the maximum size that can be
fed through the multi-bypass tray.
• Special papers such as transparency film, labels and envelope must be fed one
sheet at a time through the multi-bypass tray.

LOADING THE PAPER TRAY
1Raise the handle of the paper tray
and pull the paper tray out until it
stops.
2Adjust the paper guides on the paper tray to the copy paper
width and length. Squeeze the lever of paper guide and slide
the guide to match with the width of the paper. Move paper
guide to the appropriate slot as marked on the tray.
3Fan the paper and insert it into the tray. Make sure the edges go
under the corner hooks.
Do not load paper above the maximum height line ( ). Exceeding
the line will cause a paper misfeed.

4Gently push the paper tray back into the unit.
•After loading paper, to cancel the blinking without restarting
copying, press the clear ( ) key. The in the display will go out
and the start ( ) indicator will light up.
•
Be sure that paper is free of rips, dust, wrinkles, and curled or bent edges.
•Make sure all the paper in the stack is the same size and type.
•When loading paper, ensure there is no space between the paper and
the guide, and check if the guide is not set too narrow causing the
paper to bend. Loading paper in these ways will result in document
skew or a paper jam.
•When not using the unit for an extended period, remove all paper from
the paper tray and store it in a dry place. If paper is left in the unit for
an extended period, the paper will absorb moisture from the air,
resulting in paper jams.
•
When adding new paper to the paper tray, remove the old paper already
contained in the tray. Placing new paper on top of the paper already
contained in the tray may result in feeding two sheets at one time.

10
BYPASS FEED (including special paper)
The multi-bypass tray can be used to feed standard paper, transparency film, labels,
envelopes, and other special purpose paper. Paper measuring from A6 to A4 and in
the weight range of 56g/m2to 128g/m2can be used in this tray. (For paper weighing
from 105g/m2to 128g/m2), A4 is the maximum size.)
The multi-bypass tray
1Open the multi-bypass tray and extend the tray.
•The multi-bypass tray can hold maximum of 50 sheets of paper.
(Capacity will vary depending on the type of paper loaded.)
•The original image must be smaller than the paper or media for
copying. If the original image is bigger than the paper or media, this
may cause smudges on the edges of the copies.
To close the multi-bypass tray, perform step and then step
in the illustration and push the round projections at the right
of the tray until they click.

2Set the paper guides to the paper width. Insert the paper (print
face down) all the way into the multi-bypass tray.
3Press the tray select ( ) key to select the multi-bypass tray.
•Paper must be fed narrow side into the feed slot.
•
Special papers such as transparency film, labels, and envelopes
must be fed one sheet at a time through the multi-bypass tray.
•When copying onto transparency film, remove each copy
promptly. Do not let copies stack up. When loading an
envelope, make sure that it is straight and flat.
Note for loading envelopes
• Envelopes must be fed narrow side into the feed slot at a time.
• Do not use non-standard envelopes, and envelopes that have metal clasps, plastic
snappers, string closures, windows, linings, self-adhesive, patches or synthetic
materials. Do not use envelopes that are filled with air or envelopes that have
labels or stamps attached.
• Envelopes of which the surface is not flat because of embossing may cause the
copies/prints to become smudged.
• Under high humidity and temperature conditions the glue flaps on some envelopes
may become sticky and be sealed when copied.
• Use only envelopes which are flat and crisply folded. Curled or poorly formed
envelopes may cause misfeeds.
• It is recommended that you perform a test print before performing the actual copy
job.
Note for loading thick paper
Copying on thick paper requires higher fusing temperature setting. Set the user
program 29 to "2 (High)" when using thick paper. (See page 20 and 21.)

This chapter explains basic and other copying functions.
The unit is equipped with a one-page memory buffer. This memory allows the unit to
scan an original once only and make up to 99 copies. This feature improves
workflow, reduces operation noise from the copier, and provides higher reliability by
reducing wear and tear on the scanning mechanism.
COPY FLOW
If the unit does not function properly during use, or if a function cannot
be used, see "TROUBLESHOOTING THE UNIT" (p.27).
1 Make sure that paper has been loaded in the paper tray (p.8),
or multi-bypass tray (p.10) and check the paper size (p.7).
If paper is not loaded, see page 8.
2 Turn on the unit (p.13).
3 Place the original.
When using the original table, see "ORIGINAL PLACEMENT" (p.15).
When copying onto A4 paper or a large size, pull out the paper output tray
extension.
5 Start copying.
Press the start ( ) key.
4 Select the copy settings.
If you wish to copy using the initial settings (p.14), proceed to the next
step.
To set the number of copies, see page 16.
To adjust the resolution and contrast settings, see page 16.
To enlarge or reduce the copy, see page 18.
To change the tray, see page 18.

CONNECTING THE POWER CORD
1Ensure that the power switch of
the unit is in the OFF position.
Insert the attached power cord
into the power cord socket at the
rear of the unit.
2Plug the other end of the power cord into the nearest outlet.
Power on
Ensure that the power switch of the unit is
in the OFF position. Plug the other end of
the power cord into the nearest outlet.
Turn the power switch on the left side of
the unit to the "ON" position. The start
( ) indicator will light up and other
indicators which show the initial settings
of the operation panel will also light up to
indicate the ready condition. For the initial
settings, see the "Initial settings of
operation panel" described on the next page.
If you use the unit in a country other than the country where the unit was
purchased, you will need to make sure that your local power supply is
compatible with your model. If you plug the unit into an incompatible
power supply, irreparable damage to the unit will result.
Only insert the power cord into a properly grounded wall socket.
Do not use extension cords or power strips.
•The unit will enter a power save mode once the set time has elapsed
without any unit operation. The settings of the power save modes can
be modified. See "USER PROGRAMS" (p.20).
•The unit will return to the initial settings a preset amount of time after
the end of copy or scanning job. The preset amount of time (auto
clear time) can be changed. See "USER PROGRAMS" (p.20).

About the scan head
The scan head lamp remains on constantly when the unit is in the ready condition
(when the start ( ) indicator is illuminated).
The unit adjusts the scan head lamp periodically to maintain copying quality. At this
time, the scan head moves automatically. This is normal and does not indicate unit
trouble.
Initial settings of operation panel
When the unit power is on, the operation panel will revert to the initial settings when
the time set with the "Auto clear time" setting (p.19) elapses after a copy is finished,
or when the clear ( ) key is pressed twice.
The initial settings of the operation panel are shown below.
When copying is begun in this state, the settings in the following table are used.
Power off methods
If not used for a certain period of time, the unit will automatically enter auto power
shut-off mode (p.20) in order to minimise power consumption. In cases where the
machine will not be used for a long time, turn off the power switch and remove the
power cord from the outlet.
