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

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 server and you have checked the
hardware and network as described in the previous steps, then check the following:
It is always a good idea to try following in order to eliminate the possibility of Setup
errors.
Turning off the printer and then again,
Deleting and recreating the print server and creating a new print queue in order to
eliminate the possibility of setup errors.
1. The problem may be the result of mismatched or duplicate IP address.
Verify that the IP address is correctly loaded into the print server (via the
configuration page. Make sure that no other nodes on the network have this
address (DUPLICATE IP ADDRESS ARE THE BIGGEST CAUSE OF
TCP/IP PRINTING PROBLEMS).
2. Make sure that the TCP/IP protocol of the print server is enabled.
3. Verify that host computer and the print server are either on the same subnet,
otherwise that the router is properly configured to pass data between the two
devices.
