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.
l Readable width
210 mm max.

7. Use of Document Carrier Sheet
A document carder sheet must be used for the following documents.
l Those with tears.
l Those smaller than size 148 mm (W) x 128 mm (L).
l Carbon-backed documents
Ensure document is
straight in the carrier.
Place the document

feeder with the clear film
side down
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.

either jack.
Place the handset on the handset rest.
@Mount the original document tray.
lHold the tray vertically, bend it slightly at the center, and insert
the tabs into the holes on the top of the machine as shown.
0 Mount the received document tray.

machine.
lIf desired, flip the tray extender out.
@Mount the paper tray.
lSlide the tray in as shown until it clicks into place.
@Mount the original document out tray.
lPlace the original document out tray on the paper tray. Slide it
in or out to fit the length of the original.
Insert the small modular plug which terminates the FOBOTP adap-
tor line cord into the jack on the back of the machine marked TEL.
LINE. Plug the F080TP adaptor into the telephone jack on the
wall.
Plug the power cord into a 230 - 240 V, grounded (9prong) AC
outlet.
Press the power switch to turn on the power.
Adjust the volume switches on the left side of the machine:
l RINGING VOLUME: Set the switch at high (H), medium (M), or
low (L) as desired.
l SPEAKER VOLUME: Adjust the setting from high (H) to low
(L) as desired.
Set the mode of dialing with the DIAL switch. Select 7” if you are
on a touch-tone line, or “P” if you are on a pulse dial (rotary) line.
.
.
Be sure to make the correct setting, or you will not be able to
make a call.
WARNING NOTICE: For all units installed in New Zealand,
only the T setting for tone dialing is permitted. The P setting for
pulse dialing does not operate properly and must not be used.

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.

SW19 No.1 - 4 Number of rings for auto receive
When the machine is set in the auto receive mode, the number of
rings before answer is made can-e selected. It may be set from one
to nine rings using a binary number. Since the facsimile telephone
could be used as an ordinary telephone if the handset is taken off the
hook before connection is made to the facsimile while ringing, it
should be programmed to the user’s choice. If a facsimile calling beep
is heard when the handset is taken off the hook, press the
START/COPY key and put the handset on the hook to have the
facsimile start receiving. If it is set to above 9, receive rings are
automatically set to 1.

remain in the manual receive mode. Entering a binary number 0 will
force the machine to remain in the manual answer mode. If a number
between 1 and 9 is entered, the machine will go into the answer
mode after the given number of rings. However, it can be used as an
ordinary telephone if the handset is taken off the hook before this
programmed number has elapsed. Entry of a number above 9 will set
the machine to 0.
