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.

•
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).•

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.

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

•
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.

							•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.

							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.
