Number of pages that can be placed into the feeder at anytime is as follows:

Normal size: max. ADF 5 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

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 yello w, 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 before 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.

Readable width

• Readable length

This is the length of the document sent minus 0.2" (5mm) from the top and bottom edges.

7. Use of Document Carrier Sheet

A document carrier sheet must be used for the following documents.

• Those with tears.

• Those smaller than size 5.8" (W) x 5.5" (L) (148mm (W) x 140mm

(L)).

• Carbon-backed documents

TELEPHONE JACK

A standard RJ11C 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 jac k which is not an RJ11C jac k may

result in damage to the machine or your telephone system. If you do not know what kind of jack you have, or need to have one installed, contact the telephone company.

Make print straight across paper E.G. Place the document carrier in 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.

• 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

T ake the f ollowing points into consideration when selecting a site f or 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

AC 120V, 60Hz, 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...

Condensation may from on the reading glass if the machine is moved from a cold to a warm place. This will prevent proper scanning of documents for transmission. Tur n on the power and wait approximately 2 hours before using machine.

2. Assembly and connections

Plug the power cord into a 120 V, 60 Hz, grounded (3-prong) AC outlet.

• Caution: Do not plug the power cord into any other kind of outlet.

This will damage the machine and is not covered under the warranty.

• The machine does not have a power on/off switch, so the po wer is

turned on and off by simply plugging in or unplugging the power cord.

Connect the handset as shown and place it on the handset rest.

♦ The ends of the handset cord are identical, so they will go into

either jack.

Make sure the handset cord goes into the jack marked with a handset symbol on the side of the machine!

Use the handset to make ordinary phone calls, or to transmit and receive faxes manually.

Attach the original document support as shown below.

1 – 4

Insert one end of the line cord into the jack on the back of the ma-

chine marked TEL. LINE. Insert the other end into a standard (RJ11C) single-line wall telephone jack.

TEL. LINE

Note: The fax machine is set for touch-tone dialing. If you are on a pulse dial (rotary) line, you must set the fax machine for pulse dialing. Press the keys on the operation panel as follows:

Flip up the front paper guide.

Remove the packing paper.

4. Loading the thermal paper (FO-20PRw)

• Your f ax machine prints incoming fax es on a special kind of paper called thermal paper.

• The fax machine’s print head creates text and images by applying heat to the thermal paper.

Grasp the finger hold as shown and pull up to open the operation panel.

Insert the leading edge of the paper into the slot as shown. Continue

to push the paper through the slot until it comes out the opening in the front of the machine.

Make sure the paper comes out straight, and then flip down the pa-

per guide.

Flip up the front paper guide.

Unwrap the roll of thermal paper and place it in the compartment.

♦ Important: The roll must be placed so the leading edge of the

paper unrolls as shown. (The paper is only coated on one side for printing. If the roll is placed backwards, the paper will come out blank after printing.)

YES

NO!

Close the operation panel, making sure it clicks into place.

• A short length of the paper will feed out. Grasp the paper by the edge and pull upward to tear it off.

5. Clearing a jammed document

If the original document doesn’t feed properly during transmission or copying, or DOCUMENT JAMMED appears in the display, first try pressing the STAR T ke y . If the document doesn’t f eed out, open the operation panel and remove it.

Important:

Do not try to remove a document without first releasing it as explained below. This may damage the feeder mechanism.

Grasp the finger hold and pull up to open the operation panel.

Flip down the green levers on each side of the white roller.

Close the operation panel, making sure it clicks into place.

• Press down on both front corners of the panel to make sure it clicks into place.
