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.
