F• Firewall It is a system that prevents an unlawful computer access in the network. To prevent, you can use the firewall function of a broadband router, the security software installed in the computer, or operation system for computer. I • IEEE 802.11b International standard for wireless LAN using the 2.4 GHz frequency range with a throughput of up to 11 Mbps. • IEEE 802.11g International standard for wireless LAN using the 2.4 GHz frequency range with a throughput of up to 54 Mbps. Compatible with 802.11b. • IEEE 802.11n International standard for wireless LAN using the 2.4 GHz and 5 GHz frequency ranges. Even when using two or more antennas simultaneously or obtaining a bigger transfer rate than before by using multiple communication channels at the same time, the transmission speed may be influenced by the connected apparatus. At the maximum transfer rate of 600 Mbps, it is possible to communicate with multiple computer terminals within a dozen or so metre radius. Compatible with 802.11b and 802.11g. • Infrastructure Client computer and machine setup where all wireless communications pass through an access point. • IP Address A unique number with four parts separated by dots. Every network device that is connected to the Internet has an IP address. Example: 192.168.0.1 An IP address is usually assigned by an access point or a DHCP server of the router automatically. • IPv4/IPv6 They are internetwork-layer protocol used on the internet. IPv4 uses 32-bit addresses and IPv6 uses 128-bit addresses. K • Key Format Select either ASCII or Hex as the WEP key format. The character that can be used for the WEP key differs depending on the selected key formats. ◦ ASCII Specify with a 5 or 13-character string that can include alphanumeric and underscore "_" characters. It is case-sensitive. 331
◦Hex Specify a 10-digit or 26-digit string that can contain hexadecimal (0 to 9, A to F, and a to f).• Key Length Length of the WEP key. Select either 64 bits or 128 bits. Longer key length allows you to set a more complex WEP key. L • Link Quality The status of connection between the access point and the printer excluding noise (interference) is indicated with a value from 0 to 100%. • LPR A platform-independent printing protocol used in TCP/IP networks. It is not supported bidirectional communication. M • MAC Address Also known as the physical address. A unique and permanent hardware identifier that is assigned to network devices by its manufacturer. MAC addresses are 48 bits long and are written as a hexadecimal number separated by colons, i.e., 11:22:33:44:55:66. O • Operation Status Indicates the status on whether the printer can be used. P • Proxy server A server that links a LAN-connected computer to the Internet. When using a proxy server, specify the address and the port number of the proxy server. • PSK An encryption method employed by WPA/WPA2. R • Router A relay device to connect to another network. 332
S• Signal Strength The strength of the signal received by the printer from the access point is indicated with a value from 0 to 100%. • SSID Unique label for wireless LAN. It is often represented such as a network name or an access point name. SSID distinguishes one wireless LAN from another to prevent interference. The printer and all clients on a wireless LAN must use the same SSID in order to communicate with each other. The SSID can be up to 32 characters long, and is made up of alphanumeric characters. The SSID may also be referred to by its network name. • Stealth In the stealth mode, an access point hides itself by not broadcasting its SSID. The client must specify the SSID set to the access point to detect it. • Subnet Mask IP address has two components, the network address and the host address. Subnet Mask used to calculate the Subnet Mask address from the IP address. A Subnet Mask is usually assigned by an access point or a DHCP server of the router automatically. Example: IP Address: 192.168.127.123 Subnet Mask: 255.255.255.0 Subnet Mask Address: 192.168.127.0 T • TCP/IP Suite of communications protocols used to connect hosts on the Internet or the LAN. This protocol allows different terminals to communicate with each other. • TKIP An encryption protocol employed by WPA/WPA2. U • USB Serial interface designed to enable you to "hot-swap" devices, i.e., by plugging and unplugging them without turning off the power. 333
W• WCN (Windows Connect Now) Users running Windows Vista or later can obtain the setting information directly via wireless network (WCN-NET). • WEP/WEP Key An encryption method employed by IEEE 802.11. Shared security key used to encrypt and decrypt data sent over wireless networks. This printer supports key length of 64 bits or 128 bits, key format of ASCII code or Hexadecimal, and key number of 1 to 4. • Wi-Fi International association that certifies interoperability of wireless LAN products based on the IEEE 802.11 specification. This machine is a Wi-Fi authorized product. • Wireless LAN A network that, instead of being connected by physical wires, is connected by a wireless technology, such as Wi-Fi. • WPA Security framework announced by the Wi-Fi Alliance in October 2002. The security has been strengthened more than WEP. ◦ Authentication WPA defines the following authentication methods: PSK that can be used without an authentication server, plus WPA-802.1x that do require an authentication server. This machine supports WPA-PSK. ◦ Passphrase This encrypted key is used to perform WPA-PSK authentication. The passphrase should be a string of 8 to 63 alphanumeric characters or a 64-digit hexadecimal value. • WPA2 Security framework released by the Wi-Fi Alliance in September 2004 as a later version of WPA. Provides a stronger encryption mechanism through Advanced Encryption Standard (AES). ◦ Authentication WPA2 defines the following authentication methods: PSK that can be used without an authentication server, plus WPA2-802.1x that do require an authentication server. This machine supports WPA2-PSK. ◦ Passphrase This encrypted key is used to perform WPA2-PSK authentication. The passphrase should be a string of 8 to 63 alphanumeric characters or a 64-digit hexadecimal value. 334
•WPS (Wi-Fi Protected Setup) WPS is a standard for easy and secure establishment of a wireless network. There are 2 primary methods used in the Wi-Fi Protected Setup: PIN entry: a mandatory method of setup for all WPS certified devices Push button configuration (PBC): an actual push button on the hardware or through a simulated push button in the software. 335
RestrictionsIf you use a printer over the wireless LAN, the printer may recognize nearby wireless systems, you should set a network key (WEP or WPA/WPA2) to the access point to encrypt wireless transmission. Wireless communication with a product that does not comply with the Wi-Fi standard cannot be guaranteed. Connecting with too many computers may affect the printer performance, such as printing speed.336
About FirewallA firewall is a function of the security software installed in the computer or operation system for computer, and is a system that is designed to prevent unauthorized access to a network. Precautions When a Firewall Function is Enabled• A firewall function may limit communications between a printer and a computer. This may disableprinter setup and communications. • During the printer setup, you may be prompted to enable or disable communications, depending onthe firewall function of the security software or operation system. If so, choose to enable communications. • When using IJ Network Tool, you may be prompted to enable or disable communications, depending on the firewall function of the security software. If so, choose to enable communications. • If you cannot set up the printer, temporarily disable the firewall function of the security software oroperation system. Important • If you disabled the firewall function, disconnect your network from the Internet. • Some applications (like the network configuration software) override firewall settings. Check theapplication's settings beforehand. • If the printer you use is set to Get IP address automatically , the IP address changes every time the printer connects to the network. This may disable printer setup and communications, depending on the firewall settings. In this case, either change the firewall settings or assign a fixed IP address to the printer. An IP address can be set using IJ Network Tool. Changing the Settings in the Wireless LAN Sheet Changing the Settings in the Wired LAN Sheet When assigning a fixed IP address to the printer, you will need to specify an IP address with which the computer can communicate. Note • For the operation system firewall settings or the security software firewall settings, refer to the instruction manual of the computer or software, or contact its manufacturer. 337

Useful Information about InkHow is ink used for various purposes other than printing?Ink may be used for purposes other than printing. When you use the Canon printer for the first time after you install the bundled ink tanks, the printer consumes a small amount of ink in the amount to enable printing by filling the nozzles of the Print Head with ink. For this reason, the number of sheets that can be printed with the first ink tanks is fewer than the succeeding ink tanks. The printing costs described in the brochures or websites are based on the consumption data from not the first ink tank /ink cartridge but the succeeding ink tank /ink cartridge. Ink is sometimes used to maintain the optimal printing quality. To keep printer's performance, Canon printer performs cleaning automatically according to its condition. When the printer performs cleaning, a small amount of ink is consumed. In this case, all colors of ink may be consumed. [Cleaning function] The cleaning function helps the printer to suck air bubbles or ink itself from the nozzle and thus prevents print quality degradation or nozzle clogging. Does black-and-white printing use color ink? Black-and-white printing may use ink other than black ink depending on the type of printing paper or the settings of the printer driver. So, color ink is consumed even when printing in black-and-white. Why does the machine have two black ink tanks? There are two kinds of black ink in the machine: dye ink (BK) and pigment ink (PGBK). The dye ink is used mainly for printing photos, illustration, etc., and the pigment ink is used for text-based documents. Each has different purposes so that even if one runs out, another will not be used instead. If either of them runs out, the ink tank replacement is required. These two inks are automatically used depending on the type of printing paper or the settings of the printer driver. You cannot change the usage of these inks yourself. The ink lamp indicates when ink is running low.The inside of the ink tank consists of (A) the part where ink is preserved and (B) the sponge with absorbed ink. When the ink (A) runs out, the ink lamp flashes slowly to indicate that the ink is running low. Then, when the ink (B) runs out, the ink lamp flashes fast to indicate that the ink tank needs to be replaced with a new one. 339
