2.3.3 Checking with Remote Host Address
0019-0682
1) Inform the system administrator that you will check the network connection using Ping.
2) Check the remote host address with the system administrator.
3) Enter the remote host address to Ping.
- In the case of 'Reply from the host', connection to the network is working.
- In the case of 'No reply from the host', connection to the network is not working so execute the troubleshooting in the following section.
2.3.4 Troubleshooting Network Connection
0019-0683
In the case of connection failure to the network, there can be the following causes:
a. The connection between the network and the main controller PCB is faulty
b. TCP/IP setting of the machine is faulty
c. There is a fault in the main controller PCB, or in the installation of the PCB
d. User network is faulty
2.3.5 Checking with Loopback Address
0019-0685
1) Enter the loopback address (127.0.0.1) to Ping.
- In the case of 'NG', check the TCP/IP setting of the machine again, and then execute Ping again.
- In the case of 'OK', go through the following check for local host address.
2.3.6 Checking with Local Host Address
0019-0687
1) Enter the IP address of the machine to Ping.
- In the case of 'NG', check and perform the following to execute Ping again.
a. Faulty IP address of the machine:
Check the IP address setting of the machine again/Check with the system administrator that the allocated IP address is valid
b. Connection failure of the main controller PCB:
Check the connection of the main controller PCB connector
c. Faulty main controller PCB:
Replace the main controller PCB
- In the case of 'OK', the user's network environment can be the problem, so inform the status to the system administrator and ask for a measure.
2.4 Checking the Images/Operations
2.4.1 Checking Image Operation
0019-0697
1) Place a test chart on the copyboard glass, make a copy from each pickup inlet and check the followings.
- Check that there is no abnormal noise generated.
- Check the image quality in each magnification.
- Check that the number of sheet set is properly applied.
2) Specify the additional function mode items (date, time etc.) when required by users.
3) Specify the mechanical specification settings related to users when required by users.
- Enter the Service mode.(Main Menu > 2 > 8 > Main Menu)
- COPIER > OPTION > USER
4) If changing a setting in service mode, turn OFF/ON the main power switch.
MEMO:
You can check whether the connection to the network is successful or failed
by executing Ping with the remote host address. Remote host address: the IP
address of the PC terminal connecting/operating with the TCP/IP network
environment that connects the host machine.
Perform this item only when connecting the host machine to the network.
MEMO:
Because the loopback address is returned just before the main controller
PCB, you can check whether the TCP/IP setting of the machine is successful
or failed by executing Ping with this loopback address.
MEMO:
Local host address is the IP address of the machine. Thus, you can check
whether the PCB is working or faulty by executing Ping with this local host
address since the reply is returned from the main controller PCB.
