3. Document Types
•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 (blue print)
Diazo copy documents of a normal contrast may be transmitted.
•Carbon copy
A carbon copy may be transmitted if its contrast is normal.
4. Cautions on Transmitting Documents
•Documents written in yellow, greenish yellow, or light blue ink
cannot be transmitted.
•Ink, glue, and correcting fluid on documents must be dry before the
documents can be transmitted.
•All clips, staples and pins must be removed from documents be-
fore transmission.
•Patched (taped) documents should be copied first on a copier and
then the copies used for transmission.
•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. ADF 20 sheets
Special size: single sheet only (manual feed)
NOTES: •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.
•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.
•Readable width

7. Use of Document Carrier Sheet
A document carrier sheet must be used for the following documents.
•Those with tears.
•Those smaller than size 148 mm (W) x 128 mm (L).
•Carbon-backed documents
NOTE: To transmit a carbon-backed document, insert a white sheet
of paper between the carbon back of the document and the
document carrier.
•Those containing an easily separable writing substance (e.g., trac-
ing paper written on with a soft, heavy lead pencil).
NOTES: •When using the document carrier, carefully read the in-
structions written on the back.
•If the document carrier is dirty, clean it with a soft, moist
cloth, and then dry it before using for transmission.
•Do not place more than one document in the carrier at a
time.
[4] Installation
1. Site selection
Take the following points into consideration when selecting a site for
this model.
ENVIRONMENT
•The machine must be installed on a level surface.
•Keep the machine away from air conditioners, heaters, direct sun-
light, and dust.
•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.
•The temperature should be between 5°and 35°C.
•The humidity should be between 30% and 85% (without conden-
sation).
ELECTRICITY
230V, 50Hz, grounded (3-prong) AC outlet is required.
Caution!
•Connection to a power source other than that specified will cause
damage to the equipment and is not covered under the warranty.
•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.
If the machine is moved from a cold to a warm place...
If the machine is moved from a cold to a warm place, it is possible
that the reading glass may fog up, preventing proper scanning of
documents for transmission. To remove the fog, turn on the power
and wait approximately 2 hours before using the machine.
TELEPHONE JACK
A standard RJ-11C telephone jack must be located near the machine.
This is the telephone jack commonly used in most homes and offices.
•Plugging the fax machine into a jack which is not an RJ-11C jack
may result in damage to the machine or your telephone system. If
you do not know what kind of jack you have, or needed to have
one installed, contact the telephone company.
2. Assembly and connections
1 Connect the handset cord to the handset and the fax as shown.
•The ends of the handset cord are identical, so they will go into
either socket.
Place the handset on the handset rest.
2 Insert one end of the line cord into the socket on the back of the
machine marked TEL. LINE. Insert the other end into a wall tele-
phone socket.
•Be sure to plug the line cord into the TEL. LINE socket. Do
not plug it into the TEL. SET socket. (Note: The TEL. SET
socket is not available in some countries.)

3 Plug the power cord into a 230V, 50Hz, grounded (3-prong) AC
outlet.
•Caution: The mains outlet (socket-outlet) shall be installed
near the equipment and shall be easily accessible.
•The fax does not have a power on/off switch, so the power is
turned on and off by simply plugging in or unplugging the power
cord.
4 Attach the received document support by inserting the ends into
the holes in the fax as shown below.
4. Loading the recording paper
1 Grasp the finger hold on the right side of the paper compartment
cover, and pull up to open the cover.
Remove the packing paper from the paper compartment.
•Caution! If you are replacing the paper, do not touch the metal
strip in the compartment. It may be hot if a document has just
been printed.
2 Unwrap the roll of fax paper and insert it in the compartment.
•Make sure the hubs on each side of the compartment fit into
the ends of the roll. The hub on the left side is mounted on a
spring to allow for insertion.
•Important: The roll must be placed so that the leading edge of
the paper feeds from over the top of the roll. (The paper is only
coated on one side for printing. If the roll is placed upside
down, the paper will come out blank after printing.)
Note: The paper roll provided is only a sample roll which is ap-
proximately 50 m long.
THERMAL PAPER: FO-40PRw
3 Pass the leading edge of the paper over the roller and through the
outlet in the paper compartment cover. Remove any slack.
4 Close the cover and then press the START key. A short length of
the fax paper will feed out. Grasp the paper by the edge and pull
upward to tear it off.
