This chapter provides useful information to help you resolve problems you may encounter with your Print

5-1. FAQ
Problem
Recommended Solution
Why can't the NetPS Control Center
detect the Ethernet/Wireless LAN
module?
Make sure the network cable is securely connected.
The NetPS Control Center may be blocked by a firewall.
Please refer to "Firewall" section to change the firewall
configuration.
Why can't I use IE to set the
Ethernet/Wireless LAN module?
Check that the LAN Module’s Gateway address is the
same as the computer’s Gateway address. Both must be in
the same Gateway domain to change the Print Server's
settings using IE.
Why can't I change the IP address of
Ethernet/Wireless LAN module?
Login to the NetPS Control Center and change the “DHCP
client” to TCP/IP.
When I use Firefox, the text on the
web interface wraps to the next line,
making it hard to read.
We have found that when using Firefox, setting the font on
the ‘Content’ tab to 14 or smaller eliminates the text wrap
and makes it much easier to read.
5-2. Firewall
If firewall software has been installed on your PC, it may block the communication between the PC and the
Print Server. This may cause the Print Server to not function properly. To solve this problem you can either
disable the firewall or configure the firewall to allow the following TCP and UDP ports:
7303, 7305, 20005, 30201, 30202, 30203
