Check the error number printed on the connection check report and take measures correspond to the error
number.
For instructions on how to print the report, see "Printing the Network Connection Check Report" on page 29.
Error number Solution
E-1 • Check that the LAN cable is securely connected to the printer and the other network devices such
as a hub.
• Check that the network device such as a hub is powered on.
E-8 • If you have set the printer’s TCP/IP setting to auto, enable DHCP of the DHCP server.
• If you have set the printer’s TCP/IP manually, the IP address is out of the valid range, such as
“0.0.0.0”, and disabled. Set a valid IP address using the operation panel of the printer or using Web-
Config.
E-9 Check the followings.
• Is the device that uses the printer turned on?
• From the device that uses the printer, is it possible to access the Internet and connect to other
computer or network devices on the same network?
If there is no problem in the above checks, but the device or other network device still cannot
connect to the printer via the network, configure the network settings again using the included
software disc.
E-10 Check the followings.
• Are other devices on the network turned on?
• If you have set the printer’s TCP/IP settings manually, is the network address (IP address, subnet
mask, and default gateway) correct?
If the network address is incorrect, correct it. You can check the IP address, subnet mask, and default
gateway in the network settings column on the connection check report.
If you have enabled DHCP, set the IP address to Auto in the printer’s TCP/IP settings. If you want to set
the IP address manually, check the printer’s IP address in the network settings column on the
connection check report, then set the address in the printer’s network settings screen. Set the subnet
mask to “255.255.255.0”.
If the printer still cannot connect to the other network devices, turn off the wireless LAN router. Wait
for about 10 seconds, and then turn the router back on.
E-11 Check the followings.
• If you have set the printer’s TCP/IP settings manually, is the default gateway address correct?
• Is the device specified for the default gateway turned on?
Set the correct default gateway address. You can check the default gateway address in the network
settings column on the connection check report.
