46 Troubleshooting at Network Printing Setups
Cannot ping this equipment
Problem description

You can check if this equipment is correctly connected to a network by executing a ping com-

mand from a computer.

If this equipment does not respond when you ping it, there is a problem either with the network

configuration or with device operation.

The following checklist helps you identify the source of the error and directs you where you can

find more information about solving it.

No Check... Yes No For Instruction, Go To...
1 Confirm that the TCP/IP
protocol suite is installed on
the client computer.
Next Step
The networking section of your
operating system documentation.
2 Look at the NIC configura-
tion page and confirm the
TCP/IP settings are correct.
Is the IP Address entered
and valid? Are the Gateway
and Subnet settings cor-
rect?
Next Step
Enter the correct TCP/IP settings.
3 Reboot this equipment.
Check the NIC Configura-
tion page that prints out. Are
the TCP/IP settings correct?
Next Step
The settings are not binding, con-
tact your service representative.
4 Try to ping this equipment
again. Did this equipment
respond to the ping?
Next Step
5 Can you ping this equip-
ment from any other com-
puter within the same
network? If not, this equip-
ment might have an IP
Address that is out of range
or invalid.
Next Step
Contact your local network spe-
cialist for a valid IP address for
this equipment.
6 Can you ping to another
computer within the same
network?
Next Step
Check the computer’s protocol
settings to make sure the gate-
way and subnet settings are cor-
rect.
7 If you have customized the
device name, you can
check if the NIC is func-
tional by restoring the
default settings. When this
equipment automatically
reboots and a NIC Configu-
ration page prints, does the
device name include the
NIC’s Unit Serial Number?
Next Step
The NIC is faulty or improperly
installed. Contact your service
representative.
