• 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.

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) (148 mm (W) x 140 mm
(L)).
Carbon-backed documents
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 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
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...
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 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 jack which is not an RJ11C 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
1
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.
Use the handset to make ordinary phone calls, or to transmit and receive docu­ments manually.
2
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 power is turned on and off by simply plugging in or unplugging the power cord.
3
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.

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
The 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.
• LED port of the contact image sensor (CIS) is kept on during the term from when start of the panel test mode to end with the STOP key.

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
meter for copy or transmit, and 1.5 meters for receive. It is possible to set it to "No limit" to transmit a long document, such as a
computer print form, etc. (In this case, the receiver must also be set to no limit.)
SW-A1 No. 5 CSI transmission
(CSI TRANSMISSION) is a switch to set whether the machine sends or does not send the signal (CSI signal) informing its own telephone No. to the remote fax. machine when information is received. When "nonsending" is set, the telephone No. is not output on the remote trans­mitting machine if the remote transmitting machine has the function to display or print the telephone No. of receiving machine, using this CSI signal.
SW-A1 No. 6 DIS receive acknowledgment during G3 transmission
Used to make a choice of whether reception of DIS (NSF) is acknowl­edged after receiving two DISs (NSFs) or receiving one DIS (two NSFs). It may be useful for overseas communication to avoid an echo sup­pression problem, if set to 1.
SW-A1 No. 7 Non-modulated carrier for V29 transmission modem
Though transmission of a non-modulated carrier is not required for trans­mission by the V29 modem according to the CCITT recommendation, it may be permitted to a send non-modulated carrier before the image signal to avoid and echo suppression problem. It may be useful for over­seas communication to avoid an echo suppression problem, if set to 1.
SW-A1 No. 8 EOL (End Of Line) detect timer
Used to make a choice of whether to use the 25-second or 13-second timer for detection of EOL. This is effective to override communication failures with some facsimile models that have longer EOL detection.
SW-A2 No. 1 ~ No. 4 Modem speed
Used to set determine the initial modem speed. The default is 9600BPS. It may be necessary to program it to a slower speed when frequent line fallback is encountered, in order to save the time required for fallback procedure.
SW-A2 No. 5 Sender’s information transmit
(SENDER’S INFORMATION TRANSMISSION) is a switch to set the function to print the content of HEADER PRINT described in the passcode list at the front end of receiver’s original when original is sent to the remote machine.
If this switch is set to "NO", the HEADER PRINT is not output at the receiving machine.
SW-A2 No. 6 H2 mode
Used to determine reception of H2 mode (15 sec transmission mode). When set to OFF , H2 mode reception is inhibited even though the trans­mitting machine has H2 mode function.
SW-A2 No. 7 Communication error treatment in RTN sending mode (Reception)
Used to determine communication error treatment when RTN is sent by occurrence of a received image error in G3 reception. When it is set to "1", communication error is judged as no error.
SW-A2 No. 8 CNG transmission
When set to "0" , this model allows CNG transmission by pressing the Start key in the key pad dialing mode. When set to "1", CNG transmis­sion in the key pad dialing mode cannot be performed. In either case, CNG transmission can be performed in the auto dial mode.
SW-A3 No. 1, No. 2 CED tone signal interval
For international communication, the 2100Hz CED tone may act as an echo suppression switch, causing a communication problem.
Though SW-A3 No. 1 and No. 2 are normally set to 0, it should be changed this time between the CED tone signal to eliminate the communication problem caused by echo.

2. Document feed operation
1) The document placed in the hopper actuates the document sensor. After one second, the pulse motor starts to drive the paper feed roller. The document is automatically taken up into the machine, and stopped at the document sensor.
2) When a specified number of pulses are received from the document sensor after the document lead edge is sensed, scanning is started.
3) When a specified number of pulses are received from the document sensor after the document rear edge is sensed, scanning is termi­nated and the document is fed through.
4) If the document sensor is active (i.e., another document is in the hopper), when the preceding document scanning is completed and it is fed out, the next document is taken up into the machine. If the document sensor is not active (i.e., there is no document in the hop­per), when the document is fed out, the operation is terminated.

1) Make sure that the documents are of suitable size and thickness, and free from creases, folds, curls, wet glue, wet ink, clips, staples and pins.
2) Place documents face down in the hopper. i) Adjust the document guides to the document size. ii) Align the top edge of documents and gently place them into the
hopper. The first page under the stack will be taken up by the feed roller to get ready for transmission.
NOTES: 1) Curled edge of documents, if any, must be straighten
out.
2) Do not load the documents of different sizes and/or thicknesses together.
