5-1. Q & A
Problem Recommended Solution
Why the Control Center can not detect
the Ethernet/Wireless LAN module? Make sure the network cable is connected correctly.
The Control Center may be blocked by firewall. Please refer
to "Firewall" section to change the firewall configuration.
Why I can not use IE to set the
Ethernet/Wireless LAN module? Please check the module’s Gateway address is same as
the computer’s Gateway address. Both of them must be in
the same Gateway domain for setting the Ethernet module
by IE.
Why the IP address of
Ethernet/Wireless LAN module can not
be changed? Please login to the control center and change the “DHCP
client” to TCP/IP.
5-2. Firewall
If a firewall software has been installed on your PC, it may block the communication between the PC and the
print server so that the print server can not work properly. To solve this problem, either disable the firewall or
configure the firewall to allow the following TCP and UDP ports:
7303, 7305, 20005, 30201, 30202, 30203
