    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.

    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.

    							•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.
    285
     
    						
    							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.286
     
    						
    							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.
    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.
    Note
    •
    The printer uses pigment ink. Due to the nature of the pigment ink, the ink on the printed surface may be removed when being rubbed or scratched.
    289
     
    						
    							Key Points to Successful PrintingCheck the printer status before printing!•
    Is the print head OK?
    If a print head nozzle is clogged, print will be faint and papers will be wasted. Print the nozzle check
    pattern to check the print head.
    Maintenance Procedure
    •
    Is the inside of the printer smeared with ink?
    After printing large quantities of paper, the area where papers go through may get smeared with ink.
    Clean the inside of your printer with 
    Bottom Plate Cleaning .
    Check how to load the paper correctly!
    •
    Is the paper loaded in the correct orientation?
    To load paper in a cassette, load paper WITH THE PRINTING SIDE FACING DOWN.
    Loading Paper
    A: cassette 1
    B: cassette 2
    •
    Is the paper curled?
    The curled paper causes paper jam. Flatten the curled paper, then reload it.
    "Load the paper after correcting its curl." in Paper Is Smudged/Printed Surface Is Scratched
