Description
This article provides information on the various result codes found in item 2-2 of the Network Configuration Page (LAN details).
Solution
When examining a Network Configuration Page, item 2-2 provides a result code, which indicates the status of the network connection for the printer.
Select the code that corresponds to what is printed on your Network Configuration Page.
The printer is connected correctly. If the printer isn't found on the network, or if printing isn't possible, check the following.
-
Check that security software's firewall is off.
A message may appear warning you that Canon software is attempting to access the network. If this warning message appears, set the security software to always allow access.
Quit the security software and make sure that the printer is recognized and ready to use. If so, the cause is the firewall setting. Change the firewall settings so that the printer is recognized and ready to use. For details, contact the manufacturer of the security software.
If you are using any programs that switch between network environments, check their settings. Some programs use a firewall by default.
-
Does the network name (SSID) of the printer match the network name (SSID) setting of the wireless router?
Check 3-2-6 in the printed network settings information and the network name (SSID) of the wireless router you want to connect to. If they're different, check the SSID and password of the wireless router you want to connect to, and then setup manually.
-
Is a privacy separator, SSID separator, or Network separation function enabled on wireless router?
If it's enabled, disable these functions before performing the setup. To check the settings of the wireless router, refer to the documentation that came with the router, or contact the router manufacturer.
-
If MP Drivers (Printer Driver) are not installed, install them. (Windows)
The MP Drivers can be obtained here.
The printer's Wi-Fi setting is disabled. (You can also check if the Wi-Fi icon 
does not appear on the printer's screen.)
Enable the Wi-Fi setting in the printer's settings screen.
No IP address is assigned. (You can also check that the item 3-2-12 in the printed network settings information is blank.)
Check the following items.
-
Is printer set to obtain an IP address automatically, or is wireless router requesting manual addressing?
Refer to the wireless router's manual to enable DHCP (auto-acquisition) settings on the wireless router or to set a valid IP address on the printer.
-
When you set printer's IP address manually, correct IP address may not be set.
Check the network name (SSID) and the password of the wireless router you want to connect to, the IP address applicable range, and then enter the appropriate IP address on the printer side. If you are unsure, set the printer's IP address to automatic (DHCP).
No default gateway is set.
When you set the IP address of the printer manually, enter a valid default gateway IP address. If you don't know the default gateway, set the IP address to automatic.
Unable to connect to the specified network. Check the following items.
-
Check the status of the printer and the network device (e.g. wireless router) and your computer / smartphone / tablet.
Use 2.4 GHz frequency band to communicate with this printer and a wireless router. A typical wireless router can use the 2.4 GHz and 5 GHz frequency bands. In many cases, each frequency band is assigned a different network name (SSID). Verify the network name (SSID) and password for the frequency band you connect to.
Match the network name (SSID) set for the printer with that for 2.4 GHz frequency band of the wireless router.
-
Password on your wireless router may not match password you entered.
Passwords are case sensitive.
Enter the password correctly.
-
Monitor signal status and move printer and wireless router as necessary.
-
Place the printer and wireless router where there are no obstacles between them. Wireless communication between different rooms or floors is generally poor.
-
Wireless communication can be impeded by building materials containing metal or concrete. If the printer cannot communicate with the computer over a Wi-Fi due to a wall, place the printer and the computer in the same room.
-
After changing the installation location, print out the network settings information again and check the status of the signal. Compare with the value in section 3-2-1 in the printed network settings information to determine the installation location.
-
-
Check wireless channel number of Wi-Fi you are using on computer.
Make sure that the wireless channel number on the wireless router is included in the wireless channel number you checked. If the wireless channel number set for the wireless router is not included, change the wireless channel number of the wireless router.
-
For Wi-Fi connections, check if the computer is restricted from the wireless router.
The wireless router settings may be limiting the number of devices that can be connected at the same time. Remove or relax the restrictions.
To check the settings of the wireless router, refer to the instruction manual provided with it or contact its manufacturer.
-
If problem occurs only when wireless router is in energy-saving mode, turn off energy-saving mode of wireless router.
If the problem seems to occur suddenly, it may be resolved by updating the wireless router firmware (e.g. update interval of a key, problems of DHCP update interval, etc.). For details, refer to the wireless router's instruction manual.
-
If the printer is connected to an AirPort Base Station via LAN, make sure you use alphanumeric characters for the network name (SSID). (macOS)
There may be a problem with the signal.
Check the following items.
-
Place the printer and wireless router where there are no obstacles between them. Wireless communication between different rooms or floors is generally poor.
-
Wireless communication can be impeded by building materials containing metal or concrete. If the printer cannot communicate with the computer over a Wi-Fi due to a wall, place the printer and the computer in the same room.
-
After changing the installation location, print out the network settings information again and check the status of the signal. Compare with the value in section 3-2-1 in the printed network settings information and place the printer in the location with a higher value.
Too many clients are connected.
Wireless Direct does not allow more than 5 devices to be connected.
If you want to connect additional devices to the printer, unplug any devices that are not in use before adding them.

The noise level is high and does not differ from the signal level due to various devices other than the printer.
-
If devices (microwave oven, external hard disk drive, and other USB 3.0 devices) that emit radio waves of the same frequency bandwidth as a wireless router is nearby, it may cause interference. Place the printer and the wireless router as far away from interference sources as possible.
-
After you change the location of the printer, check the signal quality. Compare the value of 3-2-2 in the network settings information and place the printer in the location with a higher value.
