Troubleshooting for Network Connection Report

Check the error code and the messages on the network connection check report and solve the problems.

a: Error codes and solutions

Error code
Solutions
E-1
Check the following:
The network cable is connected to network devices such as the printer or a hub.
Network devices, such as a hub, are turned on.
E-2
Check that the access point (router) is turned on. If it is turned off, turn it on and then perform network setup again.
Place your printer close to the access point (router).
If you have manually entered the wireless network name (SSID), confirm whether or not your wireless network name (SSID) is correct. If it is incorrect, enter it again. Your wireless network name (SSID) is printed on the report.
If you have set up the network using WPS, check whether or not your access point supports WPS.
If you want to set up an Ad Hoc connection, you need to set up Ad Hoc for your computer first. Perform Ad Hoc setup for your computer, and then perform network setup for your printer again.
E-3
Check that the computer you want to connect to is turned on. If it is turned off, turn it on and perform network setup for your printer again.
Place your printer close to the computer you want to connect to.
E-4
Check that the Wi-Fi communication mode set for your access point (router) matches the one supported by your printer.
E-5
Confirm that the access point (router) is using one of the following security modes. If it is not, perform network setup again and change it to a supported security mode.
WEP-64bit(40bit)
WEP-128bit(104bit)
WPA PSK*1(TKIP)
WPA2 PSK*2(TKIP)
WPA PSK*1(AES)
WPA2 PSK*2(AES)
WPA(TKIP/AES)
WPA2(TKIP/AES)
*1: Also called "WPA Personal".
*2: Also called "WPA2 Personal".
E-6
See the instruction manual that came with your access point (router) for more information on the MAC address filtering function. If the filtering function is enabled, register your printer's MAC address to prevent your printer from being filtered.
If you have used the WEP security mode for your access point to enable Shared authentication, confirm that both authentication key and index are correct.
E-7
The security key set for the access point (router) and the entered security key do not match. Set up your network again using the correct security key. The security key is case sensitive.
E-8
Check whether or not the DHCP function for the access point (router) is enabled. If it is disabled, change it to enabled.
If you have set the IP address manually, the IP address is outside the supported range (invalid). Enter the correct IP address.
E-9
1. Check the following
Check that the power is on for devices, such as the computer, that want to use the printer.
Check that devices that want to use the printer, such as the computer, are on the same network.
2. If you have checked the above points, perform network setup using the software disc.
E-10
1. Check the following:
Other devices on the network are turned on.
The network addresses, such as the IP address, subnet mask and default gateway, set manually for the printer are correct.
2. If the network addresses are incorrect, set the correct addresses using the printer's LCD panel. Your network addresses are printed on the report.
E-11
1. Check the following:
The default gateway address set manually for the printer is correct.
The device specified as a default gateway is turned on.
2. If the default gateway address is incorrect, set the correct address using the printer's LCD panel. Your default gateway is printed on the report.
E-12
1. Check the following:
Other devices on the network are turned on.
The network addresses, such as the IP address, subnet mask and default gateway, set manually for the printer are correct.
The subnet mask and default gateway for the printer are the same as the one for other devices.
The printer's IP adrress does not overlap with other devices.
2. If you have checked all of the above points, try the following:
Using the software disc, make the network setup on the computer that is using the same network as the printer.
If your printer is listed in the printer list, set the IP address for the printer on the IP address setup screen.
If your printer is not listed, the security key may be incorrect. Perform network setup using the printer's LCD panel and enter the correct security key.
You can register multiple security keys for the access point in WEP security mode. If multiple keys are registered, check if you have entered the first key registered.
E-13
1. Check the following:
Network devices such as the modem, hub, and router are turned on.
The IP address for network devices other than the printer is set manually (If the IP address for the printer is assigned automatically but other network devices manually, the printer's network may differ from other network devices).
2. If you have checked all of the above points, try the following:
Using the software disc, make the network setup on the computer that is using the same network as the printer.
If your printer is listed in the printer list, set the IP address for the printer on the IP address setup screen.
If your printer is not listed, the security key may be incorrect. Perform network setup using the printer's LCD panel and enter the correct security key.
You can register multiple security keys for the access point in WEP security mode. If multiple keys are registered, check if you have entered the first key registered.


b: About the network environment

The following messages are tips for improving the network environment.

*Signal strength is low. If you have problems printing or scanning, improve your wireless network environment.
Due to low signal strength, printing speed may be slow or printing may be interrupted.
Place the printer close to the access point (router) and remove any obstacles between the access point and the printer.
*A router/access point channel conflict has been detected. If you have problems printing or scanning, improve your wireless network environment.
Signal interference can be caused by other wireless networks being used in nearby rooms or buildings. Placing the printer close to the access point (router) may improve the environment.

Place the printer close to the access point (router) and remove any obstacles between the access point and the printer. And check the channel settings of the access point (router). See the manual that came with your access point (router) for more information.
*Multiple network names (SSID) that match your entered network name (SSID) have been detected. Confirm network name (SSID).
You are connecting to a different access point (router). Change the SSID for the access point you want to connect to, and then perform network setup for your printer again.
*No more devices can be connected. Disconnect one of the connected devices if you want to add another one.
If you want to add a new device, disconnect one of the current devices using the device's Wi-Fi settings, or disconnect all devices by changing the password from your printer.
