3. Document Types
l Normal paper
Documents handwritten in pencil (No. 2 lead or softer), fountain
pen, ball point pen, or felt-tipped pen can be transmitted.
Documents of normal contrast duplicated by a copying machine
can also be transmitted.
. Diazo copy (blueprint)
Diazo copy documents of a normal contrast may be transmitted.
l Carbon copy
A carbon copy may be transmitted if its contrast is normal.
4. Cautions on TransmitMg Documents
l Documents written in yellow, greenish yellow, or light blue ink
cannot be transmitted.
l Ink. glue, and correcting fluid on documents must be dry before
the documents can be transmitted.
l All clips, staples and pins must be removed from documents
before transmission.
l Patched (taped) documents should be copied first on a copier and
then the copies used for transmission.
l All documents should be fanned before insertion into the feeder to
prevent possible double feeds.
5. Automatic Document Feeder Capacity
Number of pages that can be placed into the feeder at anytime is as
follows:
Normal size: max. 20 sheets (52 - 74.3 g/m2)
Special size: single sheet only (manual feed)
NOTES: l When you need to send or copy more pages than the
feeder limit, place additional pages in feeder when last
page in feeder is being scanned.
l Place additional pages carefully and gently in feeder.
If force is used, double-feeding or a document jam may
result.
6. Readable Width & Length
The readable width and length of a document are slightly smaller than
the actual document size.
Note that characters or graphics outside the effective document scan-
ning range will not be read.

Direction of insertion
NOTE: To transmit a carbon-backed document, insert a white
sheet of paper between the carbon back of the document
and the document carrier.
l Those containing an easily separable writing substance (e.g., trac-
ing paper written on with a soft, heavy lead pencil).
NOTES: l When using the document carrier, carefully read the in-
structions written on the back.
l If the document carrier is dirty, clean it with a soft, moist
cloth, and then dry it before using for transmission.
l Do not place more than one document in the carrier at a
time.
[5] Installation
1. Site selection
Take the following points into consideration when selecting a site for
this model.
ENVIRONMENT
l The machine must be installed on a level surface.
l Keep the machine away from air conditioners, heaters, direct sun-
light, and dust.
l Provide easy access to the front, back, and sides of the machine.
In particular, keep the area in front of the machine clear, or the
original document may jam as it comes out after scanning.
l The ambient temperature should be between 5’ and 35’C (Recom-
mend temperate 15 to 35’C). __
l The humidity should be betweenJO% and 85% (without conden-
sation).
ELECTRICITY
A230 - 240 V, 50 Hz, grounded (3-prong) AC outlet is required.
Caution!
l Connection to a power source other than that specified will cause
damage to the equipment and is not covered under the warranty.
l If your area experiences a high incidence of lightning or power
surges, we recommend that you install a surge protector for the
power and telephone lines. Surge protectors can be purchased at
most telephone specialty stores.

5. Loading printing paper
Selecting paper
The inkjet printer in your FO-3700 is designed to work well with most
types of plain paper. Bond paper generally produces the best results,
and plain paper manufactured for high-quality photocopying is also
good. However, variation in paper composition may significantly af-
fect print quality, and you should therefore test paper (printing on both
sides) before purchasing large quantities to be assured of the quality
you desire.
Size and weight
A4 size paper from 60 to 90 g/m* can be used.
Printing side
Plain paper has a ‘print’ side which should be used to obtain the best
print quality. The print side is not visible to the naked eye, so check
the label on the end of the package before removing the paper. The
print side will be indicated by an arrow, symbol, or wording. Remove
the number of sheets you wish to use from the package, and load
them in the paper tray print side up as described below.
Note:
Do not use paper which is folded, curled, or tom, as it may jam in the
prfnter.
Loading paper
A maximum of 100 sheets of paper can be loaded in the paper tray.
Note: Do not remove the paper tray from the machine to load paper
(if the tray is not correctly in the machine when paper is
loaded, the paper sensor will not be able to detect the paper).
@ Remove the original document out tray.
@Pull the tray extender out slightly.
@Fan the paper, and then tap the edge against a flat surface to
even the stack.
P
FO-3700A --+s
@Insert the paper into the tray, print side up.
l Make sure it fits squarely against the inside of the machine.
@Push the tray extender back in.
l Make sure it fits snugly against the paper.
@Replace the original document out tray.
About the printable area
The area of the page on which the FO-3700 can print is slightly
smaller than the page itself. The following dimensions are averages,
and there may be slight deviation from these dimensions depending
on how the paper is loaded in the tray.
Printing width: 203 mm
Printing length: The length of the page minus 1.5 mm from the top,
and 12 mm from the bottom.
The FO-3700 has been set at the factory to automatically reduce the
size of received documents to 92%. This can be configured for 100%
reception by user switch. This ensures that data at the extreme edges
of A4 size documents is not lost.
Note: If you receive a document which is too long to be printed on
one sheet of paper, the remainder will be printed on a second
paw.
