10-2 Troubleshooting
1. Wait about two minutes after the printer is powered on and then run a printer
self-test. I order to do this, the Monarch printer must first be placed in dump
mode so that it is capable of receiving ASCII text data. If the self-test does not
print, then there is possibly a hardware problem. Double check the
connections.
2. Also, verify that you have set up the drivers correctly on the workstation.

1. If the self-test page prints but you cannot print documents, first check the
network connection and cabling.
2. If you are connecting to a 10baseT network, there is probably a bad connection
caused either by the 10baseT cable or the hub port. If possible, try a different
cable and hub port, or try connecting a different device (such as a PC) to the
cable.
3. 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.
4. 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 the print server
addresses through. 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).
5. Check the individual protocol troubleshooting sections in this chapter for
additional causes of intermittent printer problems.

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