Chapter 7 Troubleshooting
Connectivity problems
Use the following procedure if the printer and the network configuration page are correct, but the
network printer connectivity is not working.
1
Print a network configuration page
.
2
Click
Embedded Networking
.
3
On the
Diagnostics
menu, click
Loopback Test
.
4
On the
Loopback Test
menu, click
Execute
. This begins a continuous diagnostic that can only
be stopped by using a power-cycle. A failure is reported on a diagnostic page or with an error
message. (If the test fails, a hardware problem exits. If the test succeeds, go to step 5.)
5
Turn off the printer.
6
Turn on the printer.
7
Reenter the network information.
8
Click
Embedded Jetdirect
.
9
On the
Diagnostics
menu, click
Ping
.
10
Specify the destination IP (the default is 127.0.0.1).
11
Specify the packet size (64 to 2,048, with a default of 64).
12
Specify the timeout (1 to 100 seconds, with a default of 1).
13
Specify the count (0 to 100, with a default of 4).
Note
Use different IP addresses to test the network connectivity. Results are obtained by opening the
Ping
Results
menu and selecting the individual keys, or by configuring the printer to print the results at the
end of the test. Click the
Diagnostics
menu and then click the
View Ping Results
sub-menu for more
information.
Note
The embedded Jetdirect and EIO cards can work together simultaneously (just like two EIO cards in
the same printer). Or, if necessary as a part of troubleshooting, the embedded Jetdirect can be disabled
and an EIO card can be installed.
