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 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

220-240 V, 50 Hz, earthed (2-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. T o remove the fog, turn on the power and wait approximately 2 hours before using the machine.

TELEPHONE JACK

A standard 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 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. Connections

Connect the handset as shown and place it on the handset rest. ♦ Make sure the handset cord goes into the unmarked jack on the

side of the machine!

♦ Use the handset to make ordinary phone calls, or to transmit and

receive documents manually.

Plug the power cord into a 220-240 V, 50 Hz, earthed (2-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.

Note: The shape of the plug is different in certain countries.

♦ The machine does not have a power on/off switch, so the power

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

Note: If your area experiences a high incidence of lightning or power

surges, we recommend that you install surge protectors for the power and telephone lines. Surge protectors can be purchased from your dealer or at most telephone specialty stores.

Insert one end of the telephone line cord into the "TEL. LINE" jack. Insert the other end into a standard (RJ11C) single-line telephone wall jack.

♦ Be sure to insert the telephone line cord into the "TEL. LINE"

jack. Do not insert into the "TEL. SET" jack.

SW-D1 No. 1 ~ No. 4 Number of rings for auto receive

When the machine is set in the auto receive mode, the number of rings before answering can be 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, it should be programmed to the user’s choice. If the soft switch was set to 1, direct connection is made to the facsimile. If a facsimile calling beep was heard when the handset is taken off the hook, press the START key and put the handset on the hook to have the facsimile start receiving. If it was set to 0 accidentally, receive ring is set to 1. NOTE: If the machine is set to answer after a large number of rings, it

may not be able to receive faxes successfully. If you have diffi-

culty receiving faxes, reduce the number of rings to a maximum

of 5.
