IPP Troubleshooting
IPP Troubleshooting
T4
Use the following check list to troubleshoot your network communication problem.
Check Physical Media and Network Interface Cards
1. Verify that the Printer is powered ON.
2. Verify that the Printer 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 Printer 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 Printer and perform these tasks:
1. Under the Ethernet data label on the Report, 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 Internet Services data label, verify that this feature is Enabled. If it is NOT, enable it
following the instructions supplied under the Network Connectivity Tab of this guide.
3. Under the TCP/IP data label, determine the method being used to assign TCP/IP addressing to the
Printer. 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 Printer 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 IPP is Enabled. If it is NOT, enable the protocol following the
procedure stated under the IPP (Internet Printing Protocol) item of the NOS Selection menu,
accessed from the Network Connectivity Tab 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 Printer in the Address or Location field. Press Enter. Click the Properties button or 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 New Settings.
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.
