5. If you have a bridge or router located between the print server and 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 Brother 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.
6. If the job exits the queue but does not print, make sure that you are not trying to print a
text job to a PostScript printer. If you have a printer that is capable of automatic
language switching, make sure that the printer is not forced into PostScript mode.
Intermittent Problems
If the print server and printer start up OK, but you intermittently have problems printing,
check the following:
1. If you can print small jobs but large graphics jobs are distorted or incomplete, make
sure that you have adequate memory in your printer and the latest printer driver
installed on your computer. The latest Brother printer drivers can be downloaded from
www.brother.com.
2. Check the individual protocol troubleshooting sections in this chapter for additional
causes of intermittent printer problems.
