• 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 that 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 in this chapter 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 in this chapter for
additional causes of intermittent printer problems.
