Intermittent Problems; Tcp/Ip Troubleshooting - Brother DCP-315CN Network User's Manual

If you have a bridge or router located between the Print/Scan
server and host computer, make sure that the device is set up
to allow the Print/Scan 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/Scan 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/Scan server.

Intermittent Problems

If the Print/Scan 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

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/Scan 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 the following in order to
eliminate the possibility of setup errors.
Turning off the machine and then on again.
To eliminate the possibility of setup errors, delete and recreate the
print server, then create a new print queue.
