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 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.

FO-77U

UX-66U

5. Automatic Document Feeder Capacity

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

2Connect 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.

3Attach the original document support as shown below.

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.

•

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.

•

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 need to have one installed, contact the telephone company.

2. Assembly and connections

1Plug the power cord into a 120 V, 60 Hz, grounded (3-prong) AC outlet.

FO-77U

UX-66U

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

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., tracing paper written on with a soft, heavy lead pencil).

NOTES: • When using the document carrier, carefully read the instructions 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 sunlight, 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 condensation).

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 machine is moved from a cold to a warm place, this will prevent proper scanning of documents for transmission. Turn on the power and wait approximately 2 hours before using machine.

3. Diagnostic items description

3. 1. Soft switch mode

The soft switches are provided so that each operation mode can be set by using the operation panel.

In this mode, these switches can be checked and set.

The contents of these switches are backed up.

The available soft switches are SW-A1 to SW-K1.

The content of soft switches is shown in page 2-5 to 2-17.

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 check mode

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.

•LED part 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.

3. 5. Check pattern

This mode is used to check the status of print head. Two sheets of check pattern are printed.The following information of check pattern is printed.

1 Vertical stripes (alternate white and black lines) Approx. 35 mm

2 Full black	Approx. 70 mm
3 Full white	Approx. 35 mm

RANK 0 or 1

Note:

There is a selection RANK 0 or 1 depending on resistance value of the thermal head. RANK 0 or RANK 1 is printed at the tail of check pattern to identify.

FO-77U

UX-66U

3. 6. Signal send mode

This mode is used to send various signals to the circuit during FAX communication. Every push of START key sends a signal in the following sequence. Moreover, the signal sound is also output to the speaker when the line monitor of the soft switch is on.

[1]No signal (CML signal turned on)

[2]9600bps

[3]7200bps

[4]4800bps

[5]2400bps

[6]300bps (FLAG)

[7]2100Hz (CED)

[8]1100Hz (CNG)

[9]Pseudo Ring (models with auto TEL/FAX changeover function)

[10]END

3. 7. Memory clear

This mode is used to clear the backup memory and to reset to the factory default settings.

The content of each setting will be cleared.

Note: Be sure to execute the memory clear mode whenever you change the country select setting. The default settings of the soft switches vary according to the destinations. Therefore, if you do not execute the memory clear after changing the country select setting, some functions may not work.

3. 8. Shading mode

The mode is used for the shooting compensation. For reading, set up the special original paper.

The shooting compensation memorizes the reference data of white and black for reading.

Moreover, the memorized data is not erased even if memory clear mode is executed.

3. 9. All black print

This mode is used to check the state of the printing head and intentionally overheat it. Whole dots are printed over the interval of 2 m. If it is overheated or the printing sheet is jammed, press STOP key for the end.

3. 10. Auto feeder mode

In this mode, a document is inserted and discharged to check the auto feed function.

After this mode is started, set a document, and the document feed will be automatically tested.

3. 11. Entry data send

This mode is used to send the registered data to the other machine and to make the other machine copy the registered content. Before sending in this mode, it is necessary to set the other machine at the entry data receive mode.

The contents to be sent are as follows (the machine prints each list after the transmission has completed):

1.Telephone list data

2.Sender (cover sheet) register data

3.Optional setting content

4.Soft switch content

5.Junk fax number list

6.Country setting content

FO-77U

UX-66U

3. 12. Entry data receive

This mode is used to receive the registered data from the other machine and to make your machine register the received data. Before receiving in this mode, it is necessary to set the other machine at the entry data send mode.

After receiving is completed, the machine prints the following lists:

1.Telephone list data

2.Soft switch list

3.Junk fax number list

3.13. Message print

In this mode, all the message data, which are used for displaying indication and list print, are printed as a contrast table of the selected language and English.

3. 14. Cutter aging

This mode is used to consecutively cut the recording paper about 10 mm long and to display the number of cutting times.

(The number of cutting times is cumulatively counted unless you execute the memory clear.)

The operation is stopped in the following cases:

1.Hold down the stop key. (The cutter aging is stopped.)

2.No recording paper. (The cut operation is stopped.)

3.Recording paper jam. (The cut operation is stopped.)

3. 15. Country select

This mode is used to set line connecting parameters which correspond to each destination.

When the country select mode is selected, and then the START key is pressed, the destination (country name) currently set will be displayed. By pressing the # or key, selectable destinations (country names) are displayed. When the destination (country name) you want to choose is displayed, press the START key. Each parameter will be stored in RAM.

Destinations (Country names) you can select are as follows:

COUNTRY		COUNTRY CODE
U. S. A	(U)	00
CANADA	(C)	01
LATIN AMERICA (LA/LU)		02
ARGENTINA	(AR)	03

Note: Be sure to execute the memory clear mode whenever you change the country select setting. The default settings of the soft switches vary according to the destinations. Therefore, if you do not execute the memory clear after changing the country select setting, some functions may not work.

Do not set a country select setting which is different from that of the destination of the machine. Some functions will not work because the function and the PWB specifications are different.

4. How to make soft switch setting

To enter the soft switch mode, press the following key entries in sequence.
