5 If you have a bridge or router located between the Print/Fax
server and host computer, make sure that the device is set up
to allow the Print/Fax 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/Fax 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/Fax server.
Intermittent Problems
If the Print/Fax server and machine 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 machine and the latest printer driver installed on your
computer. The latest Brother printer drivers can be downloaded
from http://solutions.brother.com
2 Check the individual protocol troubleshooting sections in this
chapter for additional causes of intermittent printer problems.
TCP/IP Troubleshooting
If you are using TCP/IP and cannot print to the Print/Fax server and
you have checked the hardware and network as described in the
previous steps, then check the following:
Turning off the machine and then on again,
Deleting and recreating the print server and creating a new print
queue in order to eliminate the possibility of setup errors.
It is always a good idea to try following in order to eliminate
the possibility of setup errors.
