2.2 Site Selection
The installation site
lShall be free from outside vibrations, dust, etc.
lShall not be directly exposed to sunlight and sudden changes in temperature.
lMust be horizontal and flat.
lShould have enough space in front of FAX machine to allow recording paper and
documents to be stacked;
lShall not have any large, electrical noise-producing machine nearby.
2.3 Unpacking
(1) Open the top cover of the cardboard box.
(2) Take out the machine with Styrofoam from the box.
(3) Take out the machine with plastic wrapper from the box.

1-3
2.4 Check of Contents
After having taken out the machine and accompanied accessories from the cardboard box,
check the contents according to the following list:
(1)FAX machine
(2)Handset and Spring cord
(3)Documents Support
(4)AC cord
(5)Line cord
(6)User manual
(7)Ink Cartridge and SIM Card
2.5 Installation of Attachments
2.5.1 Cartridge and SIM Card
(1)Open the front cover.
(2)Remove the sealing tape from the printer head.
(3)Slide the cartridge in place.
(4)Push the lever up to lock the cartridge in position.
(5)Insert the new SIM card.
(6)Close the front cover properly using both hands.
¡¯ Avoid touching the nozzles and the electrical
contacts.
2.5.2 Handset and Line Cord
(1)Insert the handset cord into the socket upon the handset
and the other end into the socket on the base of the
facsimile.
(2)Plug the telephone line cord into the main unit.
(3)Connect the telephone or answering machine set to TEL
jack.
(4)Place handset on top of facsimile and slide the document
support into the holes on the cover of the facsimile.
(5)Plug in power cord and use the supplied cable to connect
the facsimile. (See 2.5.3)

JAfter power on, the LCD will display the INITIALIZING for a period of time. This time
is used to clean the cartridge and warm up the printer.Insert the paper tray by holding it in an
upright position,
2.5.3 AC Cord Connection
(1) The power supply is provided as follows:
Voltage range 220~240 VAC, 50/60 HZ ±3 Hz (EUROPE, AUSTRALIA)
or 100~120 VAC,50/60 Hz
(2) Check whether the voltage range of your input is within the above-mentioned voltage range
and if so, insert the mains lead into the power inlet on the back panel of the machine.
(3) Plug the main lead into a single wall outlet with a correct power supply, which is near to the
unit and is easily accessible.
(4) Check the display shows “(Date & Time)”standby mode.

2.5.4 Loading Paper
(1)Pull out the paper support.
(2)Push the lever on the right side of paper cassette
backward.
Place the paper in the cassette so that the side you want
to print on faces you and the top of the page points
downward. Take care to keep the height of the stack below
the mark on the right side of the paper cassette.
(3)The cassette holds up to 50 sheets.
(4)Align the paper on the right side of the cassette and push it
down to the bottom.
(5)Adjust the left paper guide.
(6)Pull the lever toward the front of the machine. The paper is
held in place.
¡¯ If the machine runs out of paper during a print job, the
LCD shows ADD PAPER .
The fax will be stored in the memory and printed when
more papers are refilled.

3. MAINTENANCE
3.1 Routine Inspection
Basically, the routine inspection of following items are performed about every one year after the
machine is installed. The description of routine inspection is shown in table 4.1.1.
Table 3-1Routine Inspection
NO Inspection Item Procedure Remarks
1I.S Platen Clean with ethyl alcohol.
2A.D.F. roller Clean with ethyl alcohol.
Pick up roller Check the pick up rollers for wear.
Exit roller Clean with ethyl alcohol.
3A.D.F. separation
rubber pad Clean with warm or cold water.
If this rubber is worn out, replace this rubber.
4Carrier Transport Check the following parts for wear:
·Carrier transport belt.
·Carrier guide rod.
·Idler pulley parts
5Print head carrier
assembly Check it for a loose or worn wiper and cap.
Clean the contact of print head cable by a clean dry
cloth.
Check the following parts for wear or damage:
·Rubber Backer
·Print Cartridge Latch
·Latch Spring
·Carrier
6Contact Image Sensor
(C.I.S.) Check it for stains of paper dust, etc.
Clean it with ethyl alcohol, if necessary.
7Microswitch operation
Cover switch Confirm that the LCD shows “CLOSE COVER”.
When the paper cover opened and that message
disappears when the cover closed.
·Paper sensor The LCD shows “ADD PAPER”when runs out of
recording paper.
8Lubrication Apply white grease to the motor gear and all gear
mounting stud when parts are replaced or as needed.
The carrier to carrier frame engagement.
9Cleaning Remove outside fallen materials, if any, from the
machine.
Note:
When returning all rollers to its original position, confirm that its plastic bushing of the roller
properly set into the groove of the frame unit and turn the bushing to make sure the pin point of
