2. INSTALLATIONS

2.1 General

The following flowchart outlines the installation procedure.

Site selection (see 2.2)

Unpacking (see 2.3)

Check of contents (see 2.4)

Installation of attachments (see 2.5)

Initial setting

1-1

2.2 Site Selection

The installation site

l Shall be free from outside vibrations, dust, etc. l Shall not be directly exposed to sunlight and sudden changes in temperature. l Must be horizontal and flat. l Should have enough space in front of FAX machine to allow recording paper and

documents to be stacked;

l Shall 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.

1-2

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)

1-3

J After 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.

1-4

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.
