1) Hold down the control panel power switch for 3 sec or more.
2) Operate on the touch panel according to the shut-down sequence indicated
so that the main power switch may be turned off.
3) Turn off the main power switch.
4) Connect the network cable to the machine, and turn on its main power
switch.
5) Inform the system administrator of the site that the installation work is
complete, and ask him/her to make network settings.
6) When network settings have appropriately been made, turn off and then
back on the main power as described in steps 1) through 3) above so that
the new settings are valid.

1) Make the following selections in service mode: COPIER > TEST > NET-
WORK > PING.
2) Enter the IP address using the keypad on the control panel, and press the
OK key.
3) Press the Start key.
- If the PING check is successful, the machine will indicate 'OK'.
- If the PING check fails, the machine will indicate 'NG'.

2.3.3 Making Checks Using a Remote Host Address

You can execute PING using a remote host address, thereby checking the
connection to the network.
1) Inform the system administrator that you will be checking the connection
to the network using PING.
2) Check with the system administrator to find out the remote host address.
3) Enter the remote host address you obtained in PING.
- If the indication is 'OK', the machine is correctly connected to the
network.
- If the indication is 'NG', the machine is not correctly connected to the
network. Go through the following troubleshooting steps:

If the connection to the network is not correct, you may suspect the follow-
ing:
a. Poor connection between the network and the main controller PCB (sub
LANBAR-C).
b. Wrong TCP/IP setting on the machine.
c. Faulty main controller PCB (sub LANBAR-C) or poorly mounted PCB.
d. Faulty user network.
2.4.2 Making Checks Using a Loopback Address

C3080i / iR C2550
A loopback address returns before it reaches the main controller PCB (sub
LANBAR-C); therefore, executing PING using a loopback address will en-
able you to find out whether the TCP/IP settings of the machine are correct.
1) Enter the loopback address (127.0.0.1) to PING.
- If the machine indicates 'NG', check the TCP/IP settings of the machine
once again, and then execute PING once again.
- If the machine indicates 'OK', check the local host address.
2.4.3 Making a Check Using a Local Host Address

C3080i / iR C2550
The local host address is the IP address of the machine; therefore, executing
PING using the local host address, which returns after it has reached the main
controller PCB (sub LANBAR-C), enables you to find out if the main con-
troller PCB (sub LANBAR-C) is good or not.
1) Enter the IP address of the machine to PING.
- If the machine indicates 'NG', make the following checks/corrections,
and execute PING once again.
a. Faulty IP address of the machine: check with the system
administrator to find out if the IP address (and its settings) assigned to
the machine is correct.
b. Poor connection of the main controller PCB (sub LANBAR-C):
check the connectors associated with the main controller PCB (sub
LANBAR-C).
c. Faulty main controller PCB (sub LANBAR-C): replace the main
controller PCB (sub LANBAR-C).
- If the machine indicates 'OK', suspect a fault in the user's network
environment. Report to the system administrator, ask for corrective
Perform the following work only if the machine is equipped with printer
functions.
You must select 'On' for the following mode item before making network
settings:
[Additional Fanction] > [System Settings] > [Network Settings] > [Change
Settings/Display Connection Confirm].
Go through the following steps only if the machine is connected to a
network:
If the user's network environment is based on TCP/IP, use the PING
function to see that the main controller PCB (sub LANBAR-C) has been
correctly mounted and the network settings have been correctly made. If the
user's network environment is based on IPX/SPX or AppleTalk, on the
other hand, you need not make a PING-based check.

MEMO:
The term "Remote Host Address" refers to the IP address of a PC terminal
connected to and operating in a TCP/IP network environment to which the
machine belongs.
Go through the following steps only if the machine is connected to the
network.
