2.4 Troubleshooting the Network
2.4.1 Overview
0008-3488
iR105i/iR105+ / iR9070
The instructions that follow apply only when the machine is connected to a network.
If an attempt to connect to the network fails, the following may be suspected:
a.the connection between the machine and the network is faulty.
b.the machine's TCP/IP setting is faulty.
c.the user's network is faulty.
d.the main controller PCB is faulty.
Make checks by referring to the following detailed instructions:
2.4.2 Overview

/ iR85+
The instructions that follow apply only when the machine is connected to a network.
If an attempt to connect to the network fails, the following may be suspected:
a.the connection between the machine and the network is faulty.
b.the machine's TCP/IP setting is faulty.
c.the user's network is faulty.
d.the main controller PCB is faulty.
Make checks by referring to the following detailed instructions:
2.4.3 Overview

/ iR8070
The instructions that follow apply only when the machine is connected to a network.
If an attempt to connect to the network fails, the following may be suspected:
a.the connection between the machine and the network is faulty.
b.the machine's TCP/IP setting is faulty.
c.the user's network is faulty.
d.the main controller PCB is faulty.
Make checks by referring to the following detailed instructions:
2.4.4 Making a Check Using a Loopback Address
0008-3489
iR105i/iR105+ / iR9070
A loopback address will return before it reaches the network controller. When you execute PING using a loopback address, you can find out whether the
machine's TCP/IP setting is correct.
1) Enter the appropriate loopback address (127.0.0.1) for PING.
- If 'NG', check the machine's TCP/IP setting once again, and execute PING once again.
- If 'OK', go to the next check.
2.4.5 Making a Check Using a Loopback Address
0008-3812
/ iR85+
A loopback address will return before it reaches the network controller. When you execute PING using a loopback address, you can find out whether the
machine's TCP/IP setting is correct.
1) Enter the appropriate loopback address (127.0.0.1) for PING.
- If 'NG', check the machine's TCP/IP setting once again, and execute PING once again.
- If 'OK', go to the next check.
2.4.6 Making a Check Using a Loopback Address
0008-3846
/ iR8070
A loopback address will return before it reaches the network controller. When you execute PING using a loopback address, you can find out whether the
machine's TCP/IP setting is correct.
1) Enter the appropriate loopback address (127.0.0.1) for PING.
- If 'NG', check the machine's TCP/IP setting once again, and execute PING once again.
- If 'OK', go to the next check.
2.4.7 Making a Check Using a Local Host Address
0008-3490
iR105i/iR105+
A local host address is the IP address of the machine. When you execute PING using the address, it will return after it has reached the network controller
so that you will be able to find out whether the network controller (main controller PCB) is free of a fault or not.
1) Enter the IP address of the machine for PING.
If 'NG' is indicated, perform the following, and execute PING once again:
- if the IP address of the machine is faulty, check to be sure that the IP address setting is correct or, as necessary, report to the system administrator to see
