CHAPTER 1. GENERAL DESCRIPTION
[1] Caution
1. Caution for Battery replacement
2. Precautions for using Lead-Free Solder
(Danish) ADVARSEL !
Lithiumbatteri-Eksplosionsfare ved fejlagtig håndtering.
Udskiftning må kun ske med batteri af samme fabrikat og type.
Levér det brugte batteri tilbage til leverandoren.
(English) Caution !
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the equipment manufacturer.
Discard used batteries according to manufacturer's instructions.
(Finnish) VAROITUS
Paristo voi räjähtää, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittelemaan
tyyppiin. Hävitä käytetty paristo valmistajan ohjeiden mukaisesti.
(French) ATTENTION
Il y a danger d'explosion s' il y a remplacement incorrect
de la batterie. Remplacer uniquement avec une batterie du
même type ou d'un type recommandé par le constructeur.
Mettre au rébut les batteries usagées conformément aux
instructions du fabricant.
(Swedish) VARNING
Explosionsfare vid felaktigt batteribyte.
Använd samma batterityp eller en ekvivalent
typ som rekommenderas av apparattillverkaren.
Kassera använt batteri enligt fabrikantens
instruktion.
(German) Achtung

Entsorgung der gebrauchten Batterien nur nach den vom
Hersteller angegebenen Anweisungen.
1. Employing lead-free solder
The Control PWB, LIU PWB, Power Supply PWB and Operation Panel PWB of this model employs lead-free solder.
This is indicated by the "LF" symbol printed on the PWB and in the service manual.
The suffix letter indicates the alloy type of the solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free solder
When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may
result in cold soldered joints and damage to printed patterns.)
As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommended that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer melting point (flow), to prevent damage to the
land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time.
Remove the bit as soon as a good flow is achieved.
The high content of tin in lead free solder will cause premature corrosion of the bit.
To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.
Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their
characteristics, making good soldering more difficult.
It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be
taken to clean the bit thoroughly after each use.

• 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 orig-
inal document may jam as it comes out after scanning.
• The temperature should be between 15 - 32°C.
• The humidity should be between 25% and 80% (without conden-
sation).
ELECTRICITY
AC 230-240 V, 50 Hz, earthed AC outlet is required.

[6] Scan to E-mail
The Scan to E-mail feature lets you scan a document and directly send
the image to an e-mail recipient.
• This saves you the trouble of scanning the document into a com-
puter and sending the scanned file using an e-mail program.
• The scanned document is sent as an attachment to an e-mail mes-
sage. The attached file can be in TIFF or PDF format.
Requirements
To use Scan to E-mail, you must.
• Have an Internet connection.
• Have a broadband router or LAN switch/hub through which you can
connect the machine to the Internet (the router is usually connected
to a cable modem or DSL modem).
A typical setup is shown below.
Note: The Scan to E-mail function is not compatible with mail serv-
ers that require security protection (SSL).
1. Connecting the Machine
The machine is connected using an Ethernet cable (not included).
Please purchase a 10Base-T straight-through (regular) cable that sup-
ports 10Base-T.
Connect one end of the cable to the LAN port on the machine.
Connect the other end to a LAN port on your router, switch, or hub.
• If you are uncertain which port to connect the cable to, see the
manual for the router, switch or hub.
• The connections can be made with all devices powered on.
• For other questions about how the machine should be connected,
consult your Internet service provider.
1. IP address
The machine requires an IP address to communicate on the Internet.
If your network is set up to automatically assign IP addresses, you do
not need to do anything; the machine will automatically receive an IP
address when it is connected.
If your network requires that a static (permanent) IP address be
assigned to the machine, see Network Settings to enter the IP address
and related information.
2. Checking your IP address and the connection
To check the machine's IP address and verify that the machine is able
to communicate on the network, follow these steps.
1) Press , then until [NETWORK SETTING] appears.
2) 2 Press , then to show [NETWORK INFORMA-
TION]
3) 3 Press .
• If the machine has automatically received an IP address and is
able to communicate, [IP ADDRESS/DHCP: ON] will appear on
the top line of the display, followed by the IP address on the bot-
tom line. To show the machine's host name, press .
• If a static IP address has been entered in the machine and the
machine is able to communicate, [IP ADDRESS/DHCP: OFF]
will appear on the top line of the display, followed by the IP
address on the bottom line. To show the machine's host name,
press .
• If the machine was unable to receive an IP address automati-
cally, or if the router locked up after the machine received an IP
address, [IP ADDRESS/DHCP: FAIL] / [192.168. 1 .201] will
appear. "192.168. 1 .201" is an IP address that is assigned to
the machine for diagnostic purposes when connection fails (it
cannot be used for regular communication).
• If [NOW CONNECTING/CHECK LATER] appears, press
to exit. Make sure the cable is connected correctly, wait briefly,
and then repeat the procedure again.
3. If the machine is unable to communicate...
• Check the Ethernet cable. Are the connections secure? Are you
using straight-through (not crossover) cable for 10Base-T?
• There may be a problem in the router or other device to which
the machine is connected. Try removing and then restoring the
power to the router (see the manual for the router).
• If [IP ADDRESS/DHCP: FAIL] appears, remove and then rein-
sert the Ethernet cable plug, and repeat the procedure to check
the machine’s IP address. If the same message appears, check
the device that acts as the DHCP server on your network (try
removing and restoring the power). If your router is your DHCP
server, make sure that DHCP is enabled in the router settings. If
your network does not have a DHCP server, set a static IP
address as explained.
• If a static IP address has been set, make sure that the network
settings are correct.
