7. Use of Document Carrier Sheet

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

• Those with tears.

• Those smaller than size 148mm (W) x 128mm (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

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

AC 220-230V, 50Hz, 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. Loading the imaging film (UX-3CR)

Your fax uses a roll of imaging film to create printed text and images.
The print head in the fax applies heat to the imaging film to transfer ink
to the paper. Follow the steps below to load or replace the film.

• The initial starter roll of imaging film included with your fax can print

about 30 A4 pages.

• When replacing the film, use a roll of Sharp UX-3CR imaging film.

One roll can print about 95 A4 pages.

Note: If there is paper in the paper tray, pull the paper release plate
forward and remove the paper before loading the imaging film.

1

Plug the power lead into a 220-230 V, 50 Hz, earthed (2-prong) AC
outlet.

• Caution: The mains outlet (socket outlet) should be installed near
the equipment and be easily accessable.

• The machine does not have a power on/off switch, so the power
is turned on and off by simply plugging in or unplugging the power
lead.

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.

2

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 socket.

3

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 telephone
socket.

5

Attach the original document support.

Note: The original document support has a top side and a bottom

side. If you cannot insert the tabs on the support into the holes,
turn the support over.

The available soft switches are SW-A1 to SW-M2.
The content of soft switches is shown in page 2-5 to 2-16.
The contents are set to factory default settings.

3. 2. ROM & RAM check

ROM executes the sum check, and RAM executes the matching test.
The result will be notified with the number of short sounds of the buzzer
as well as by printing the ROM & RAM check list.
Number of short sounds of buzzer 0 → No error

1 → ROM error
2 → RAM error (32Kbyte)

3. 3. Aging mode

If any document is first present, copying will be executed sheet by sheet.
If no document is present, the check pattern will be printed sheet by
sheet. This operation will be executed at a rate of one sheet per 5min­utes, and will be ended at a total of 10 sheets.

3. 4. Panel key test

This mode is used to check whether each key operates properly or not.
Press the key on the operation panel, and the key will be displayed on
the display. Therefore, press all keys. At this time,finally press the STOP
key.

When the STOP key is pressed, the keys which are not judged as
"pressed" will be printed on the result list.

SW-A1 No. 1 Protect from echo

Used to protect from echo in reception.

SW-A1 No. 2 Forced 4800BPS reception

When line conditions warrant that receptions take place at 4800 BPS
repeatedly.

It may improve the success of receptions by setting at 4800BPS.
This improve the receiving document quality and reduces handshake

time due to fallback during training.

SW-A1 No. 3 Footer print

When set to "1", the date of reception, the sender machine No., and the
page No. are automatically recorded at the end of reception.

SW-A1 No. 4 Length limitation of copy/send/receive

Used to set the maximum page length.
To avoid possible paper jam, the page length is normally limited to 0.6
