NOTES: l 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.

l Place additional pages carefully and gently in feeder.

If force is used, double-feeding or a document jam may result.

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

Acarbon 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.

[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 35OC.

The humidity should be between 30% and 85% (without conden-

sation).

ELE’CTRICITY

120V , 60H2, 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. To remove the fog, turn on the power and wait approximately 2 hours before using the machine.

@ Pull out the original document support and the output tray.

Note: When receiving faxes, copying or printing, do not let a large number of pages accumulate in the output

tray. This may obstruct the outlet and cause paper jams.

The cursor position shows the data to be set. Pressing # key moves the cursor to the right. If, however, the cursor is on data number 8, prssing # key shifts the cursor to data number 1 of the next switch number. If the switch number is the final , pressing # key will exit the soft switch mode. Pressing X key moves the cursor to the left. If, however, the cursor is on data number 1 ,Pressing X key shifts the cursor to data number 1 of the former switch number. If the switch number is I, pressing X key will not move the cursor.

@ Data setting method

Press the FUNCTION key, and the data at the position of the cursor will be reversed to 0 when it is 1 ,or to 1 when it is 0.

@ Outputting method of soft switch list

In the soft switch mode, press the REPORT key, and the soft switch list will be output. If the recording paper runs out or is clogged, the key error buzzer will sound with the process not received.

@ Storage of data

In the following case, the data of the soft switches set will be stored.

l It is shifted to set the next soft switch by pressing the START

switch.

l It is shifted to set the next soft switch with the # key l It is shifted to set the last soft switch with the X key l It is shifted to set another soft switch by inputting two digits as

the switch number.(When 2 digits are completely input.)

l Output of the soft switch list is started.

3.2. ROM 81 RAM test

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. If error does not occur, the buzzer does not sound.

( As for the print format refer to the list function specification.)

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 IO sheets.

3.4. Panel check mode

The mode is used to check whether each key properly operates or not. Since the key is displayed on LCD when the key on the operation panel is pressed, press all the keys. Here, finally press STOP key. When STOP key is pressed, the keys not judged as “pressed” are output in the result list. Here, three LED ports can be turned on alternately during the time from the start of the panel check mode to the end with the stop key.

3.5. Check pattern mode

The mode is used to check the state of the printing head. It is ended with the following pattern printed on one printing sheet.

Top skew

Black print

Horizontal lines

Vertical lines

Nozzle test (check of printer)

Even dots print

3.6. Signal send mode

The 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.

echo suppression switch, causing a communication problem. Though SW9 No.1 , 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.

SW9 No. 3 Equalizer freeze control (MODEM) This switch is used to perform reception operation by fixing the equal-

izer control of modem for the line which is always in unfavorable state and picture cannnot be receivedUsually, the control is executed according to the state of line where the equalizer setting is changed always.
