Section 5: Troubleshooting

•There is a queue setup problem, a print server setup problem, or other protocol-related problem.

CHECKING THE INTERFACE BETWEEN THE PRINT SERVER AND THE PRINTER

First make sure that the cable between the print server and printer is securely plugged in at both sides. Then:

1.Wait about two minutes after the printer is powered on and then run a printer self-test (see Section 3: Configuration for information on how to run the self-test).

If the self-test does not print, then there is possibly a hardware problem double check the connections.

In some rare instances, disabling NBUF with the command SET PORT P1 NBUF DISABLED will solve port compatibility issues.

CHECKING THE NETWORK CONNECTION AND CABLING

If the self-test page prints but you cannot print documents, first check the network connection and cabling.

1.If you are connecting to a 10baseT network, verify that the OK LED is on. If the appropriate LEDs are not on, there is probably a bad 10BaseT or 100BaseTX cable or the hub port is bad. If possible, try a different cable and hub port, or try connecting a different device (such as a PC) to the cable.

2.If you are using a repeater or hub, make sure the SQE (heartbeat) is turned off at the hub (this is the default setting for most hubs). Also, if you have a hub or multiport repeater, verify that the hub or repeater port is good by trying the print server on a different port.

3.If you have a bridge or router located between the print server and the host computer, make sure that the device is set up to allow the print server to send and receive data from the host. For example, a bridge can be set up to only allow certain types of Ethernet addresses to pass through (a process known as filtering); therefore, such a bridge must be configured to allow print server addresses. Likewise, a router can be set up to pass only certain protocols, so be sure that the desired protocol can be passed through to the print server. In the case of routers, also make sure that the protocol is routable (LAT, NetBEUI, and DLC/LLC are not routable).

4.Make sure that you are not trying to perform an illegal operation, such as attempting to print a label larger than the printer can handle.

5.Check the individual protocol troubleshooting sections provided with the Ethernet Interface Module for additional causes of intermittent printer problems.

INTERMITTENT PROBLEMS

If the print server and the printer start up OK, but you intermittently have problems printing, check the following:

1.Excessive NetWare polling can be a big cause of intermittent problems. Make sure that you have only enabled the NetWare file servers that you need for printing (do a SHOW NETWARE command from the print server console to see the enabled file servers). If you have V3.21 or earlier firmware, make sure that NetWare polling is disabled by using the console command SET NETWARE RANGE 0. If you are not using NetWare, you can disable NetWare entirely with the command SET NETWARE DISABLED.

2.Check the individual protocol troubleshooting sections provided with the Ethernet Plug-In Interface Module for additional causes of intermittent printer problems.
