							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

							•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.
363 
						

							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.364 
						

							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.

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 machine smeared with ink?
After printing large quantities of paper or performing borderless printing, the area where papers go through may get smeared with ink. Clean the inside of your machine 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 PRINT 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

							Be Sure to Check Paper Settings before PrintingBefore printing, make paper settings in the operation panel or the computer screen.
There are various types of paper, such as paper with a special surface coating for printing photos at optimal
quality and paper suitable for documents.
Each media type has specific preset settings (how ink is used and sprayed, distance from nozzles, etc.), that
allow you to print to that type with optimal image quality. The wrong paper settings may cause poor printout
color quality or scratches on the printed surface.
If you notice blurring or uneven colors, increase the print quality setting and try printing again.370
