PING
1) Press the switch at the operating section long for the shutdown sequence and turn the main power switch OFF.
2) Connect the network cable to this machine and turn the main power switch ON.
3) Notify the system administrator that the machine has been installed to request network setup.
4) Notify the system administrator of the network connection check plan and check the PING remote host address (IP address of a PC terminal in the user
network).
5) Select the service mode (COPIER>TEST>NETWORK>PING), enter the IP address checked at Step 4 from the ten-key pad of the operating section,
and press the OK key and the Start key.
- Once the network has been connected normally, OK is displayed. (End)
- If NG is displayed, check the connection of the network cable first. If the network cable is connected normally, do Step 6 and later. If the network
cable is not connected normally, repeat Step 5.
6) Select the service mode (COPIER>TEST>NETWORK>PING), enter the loopback address *(127.0.0.1), and press the OK key and the Start key.
- If NG is displayed, the TCP/IP setting of the local machine may be wrong. Return to Step 3 and check the setting again.
- If OK is displayed, the TCP/IP setting of the local machine seems correct but the network controller (main controller circuit board) may be faulty.
Check the controller at Step 7.
*: Since the loopback address signal is returned before the network controller, the TCP/IP setting of the local machine can be checked.
7) Select the service mode (COPIER>TEST>NETWORK>PING), enter the local host address (IP address of the local machine), and press the OK key.
- If NG is displayed, the IP address of the local machine may be wrong or the network controller may be faulty. Check the IP address with the system
administrator or replace the main controller circuit board.
- If OK is displayed, there seem to be no problems about the network setting of the local machine or the network controller.
Then the problem may be attributable to the user network environment. Report this to the system administrator and request action.
