IPP Troubleshooting
Use the following check list to troubleshoot your network communication problem.

Check Physical Media and Network Interface Cards

1. Verify that the Device is powered ON.
2. Verify that the Device and Workstation are using the correct cabling to communicate over the
network. Use category 3 UTP patch (NOT crossover) cable for 10 Base T communications, category
5 UTP patch (NOT crossover) cable for 10 Base T / 100 Base TX communications, and Token Ring
cabling for Token Ring networks.
3. Verify that the cable at both the Device and Workstation is fully plugged into the Network Interface
Card (NIC). Check the link light, which is typically a green LED, to make sure that it is lit. Typically,
but not always, a second light on the Network Interface Card will be intermittently flashing, indicating
the presence of network traffic. If neither of these lights is lit, there is a problem with the NIC.

Print a Settings List at the Device and perform these tasks:

1. Under the Ethernet Settings data label on the List, verify that your communications speed is
correctly set for your network and that you have a MAC address listed. The driver for your NIC works
at the Media Access Control (MAC) layer of the protocol stack. If no MAC address is shown, you
have either a bad NIC or no NIC at all. Replace or install the Network Interface Card.
2. Under the CentreWare Internet Services data label, verify that this feature is Enabled. If it is NOT,
enable it following the instructions supplied in the Network Connectivity section of this guide.
3. Under the TCP/IP data label, determine the method being used to assign TCP/IP addressing to the
Device. Verify that the IP Address, Subnet Mask, and Gateway addresses are correct for your
network and have NOT changed from their previous settings. Note: The use of DHCP (the DHCP
Server) with a short "lease" time can cause the Device to be assigned a new IP Address when it is
powered off for an extended period of time. This will interrupt communications with workstations
using the "old" IP address. If you do not want the IP address to be subject to constant changes,
either increase the lease time at the DHCP Server, or use the Static IP Addressing method as
described in the TCP/IP Protocol Configuration procedure in the NOS selection section of this
guide.
4. Under the IPP data label, verify that the IPP Port is Enabled. If it is NOT, enable the port following
the procedure stated in the IPP Configuration topic in the NOS Selection section of this guide.
5. Under the IPP data label, verify that IPP is using DNS to resolve Host Names to IP Addresses in
support of IPP printing. If it is NOT, using your workstation's Web browser enter the TCP/IP Address
of the Device in the Address or Location field. Press Enter. Click the Properties tab. Click the plus
(+) symbol to the left of the Protocol Settings file folder and select IPP in the directory tree. Verify
that the DNS Enablement Checkbox is checked. If it is NOT checked, check it with your mouse and
click Apply. Reboot the Device with the Reboot Machine button on the Status tab.
6. Under the IPP data label, verify that the Port number associated with IPP is 631. This is the port
number assigned to IPP by the Internet Assigned Numbers Authority. If the number is not 631, set it
to 631 following the instructions supplied in the Configure IPP procedure in the Internet Services
section of this guide.
