Setup Problems

Is the wireless router/access point connectable?
Use your computer or other devices to confirm whether it can be connected wirelessly.

Is the printer far from the access point, or is there an obstacle between them?
Move the printer close to the access point, or remove the obstacle.

Is the password correct?
The password is case-sensitive. Verify that the entered password is correct. A password may be called a “WEP key”, a “WPA passphrase”, a “Pre-Shared Key”, and so on according to the access point or security system being used.

Are access restrictions set on the access point?
If access restrictions are set on the access point (wireless router, etc.), register the printer’s MAC address or IP address on the access point to allow communication. For details, see the access point user’s guide.

Is the SSID (network name) hidden according to the access point settings?
If the access point stealth function, etc. is turned on to hide the SSID, enter the SSID on the control panel. See Setting up a Printer Wi-Fi Network Using the Control Panel.

Are usable wireless channels restricted on the WLAN-equipped computer?
Usable wireless channels may be restricted on a wireless-equipped computer. See the computer’s or wireless card’s user’s guide to confirm usable wireless channels. Verify that wireless channels confirmed above include channels set to the access point. If not, change the access point wireless channels.

Is the network adapter compatible with this printer’s standards?
There are different standards such as 802.11a, 802.11b, 802.11g and 802.11n for Wi-Fi devices, and electromagnetic waves of different frequencies are also used.

Does the SSID (network name) contain Non-ASCII characters?
Check if the SSID (network name) contains Non-ASCII characters. The printer cannot display Non-ASCII characters.

Is the message “The combination of IP address and subnet mask is invalid.” displayed?
Solution 1: If your broadband router (or access point) uses a DHCP function, set the TCP/IP setting so that the printer acquires an IP address automatically.
Solution 2: If you want to set the printer’s IP address manually, see the following to set the IP address and subnet mask.
1. Check the IP address for the broadband router (or access point) connected to your computer. See the broadband router’s (or access point’s) user’s guide.
2. All IP addresses are written in segments of four numerical values. In the final segment, set a unique numerical value for your printer within a range of 1 to 254. (When the router is a DHCP server or when there is another DHCP server in the network, set a value that does not conflict with the ID address range allocated by the DHCP server.)
Setting example:
IP address for the broadband router: 192.168.1.1
Example setting on the printer: 192.168.1.3
For the subnet mask, 255.255.255.0 is normally set for small-scale networks and all devices in the network use this value. Also, when a gateway value is set, use the same value as the IP address for the wireless router.

Does your computer have more than one network interface?
The scanner may not be able to communicate with computers that have multiple network interfaces. To communicate with the scanner, disable all network interfaces on your computer except for the interface connected to the scanner.

When using TCP/IP, can the computer and printer communicate?
Verify that a connection is established. See Ping command.

When using TCP/IP, is the IP address set correctly for your environment?
The factory setting is not available as is. To use this IP address, delete it once and reenter the same address. Change the printer’s IP address as appropriate for your environment.

Is wireless communication interrupted or disconnected?
See Network Settings - Confirm Network Settings on the printer’s control panel. If disconnected, restart the printer. For details on the control panel, see Setting up a Printer Wi-Fi Network Using the Control Panel.

Is the printer correctly connected to the access point (wireless router, etc.)?
See Network Settings - Confirm Network Settings on the printer’s control panel to verify the Connection. If disconnected, check the following.
The access point (wireless router, etc.) is turned on.
The Wi-Fi settings correspond to those on the target access point (wireless router, etc.).

Is Wi-Fi Setup set to Disable on the control panel?
If set to Enable, communication cannot be established on a Ethernet network. Set it to Disable.

Is the message “The combination of IP address and subnet mask is invalid.” displayed?

The factory setting is not available as is. To use this IP address, delete it once and reenter the same address. Change the printer’s IP address as appropriate for your environment.

Are the hub, Ethernet cable, etc. working properly on a Ethernet network connection?
Verify that the printer is turned on, and that the link LED of the printer-connected hub port lights/flashes. If the link LED is off, try the following.
1. Connect to another port.
2. Connect to another hub.
3. Replace the Ethernet cable.

Does the printer’s communication mode correspond to the hub or router?
Confirm whether the printer’s communication mode is appropriate for the hub or router.
See the following table to appropriately match up the communication modes of the printer and hub/router. (The printer’s default communication mode is Auto).
For the procedure on confirming/setting the communication mode of the hub/router, see the user’s guide.
