Verifying the TCP/IP connection
Verifying the TCP/IP connection
The Colorwriter is shipped from the factory with an invalid IP (Internet Protocol)
address assigned in the setup. The IP address is used on all TCP/IP networks and
must always be assigned before the Colorwriter can be verified across the network.
Setup also provides options to change the subnet mask and gateway address. Only
some customer sites will require these values to be entered in Setup. The network
administrator must enter the required TCP/IP values in Setup before the
connection between the Colorwriter and a TCP/IP network can be verified.
Because TCP/IP networks require some UNIX setup by the network
administrator, you may not be able to send a test page across the network to the
Colorwriter immediately after installation. The following procedure enables you
to verify that there is a proper connection between the Colorwriter and the
customer’s network without printing a test page.
Before you begin this procedure, verify that the Colorwriter can print a test page
from the control panel.

:
1.
Have the network administrator run Network Setup and enter the IP address that
has been assigned to the Colorwriter.
Only the network administrator should assign UNIX addresses in Network Setup.
Assigning an incorrect UNIX address can cause serious and unpredictable
network problems.
2.
With the Colorwriter in a ready state, go to a remote UNIX workstation on the
network and enter the command ping <IP address> where IP address is the
Colorwriter IP address that the network administrator assigned in Network Setup.
The server should respond with a message such as
<IP address> is alive
.
If the server informs you that the Colorwriter is not on the network with a
message such as
Host server not responding
, try the following steps. After each
step, send a
ping
command to the printer.
•
Check the connections between Colorwriter and the network. Verify that all
network connections are terminated. Restart the Colorwriter.
