Troubleshooting The Network; Overview; Making A Check Using A Loopback Address; Making A Check Using A Local Host Address - Canon iR3570 Service Manual

The term "remote host address" refers to the IP address of a PC that is connected to the TCP/IP network to which the machine is connected.
1) Inform the system administrator that you will be checking the network connection using the PING function.
2) Ask the system administrator for the appropriate remote host address.
3) Enter the remote host address for PING.
4) If the result is 'OK', the connection to the network is correct.
5) If the result is 'NG', the connection to the network is not correct; start the following troubleshooting work:

2.4 Troubleshooting the Network

2.4.1 Overview

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 Making a Check Using a Loopback Address

iR2270 / iR2870 / iR3570 / iR4570 / / / / / iR2230 / / iR3530 /
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.

2.4.3 Making a Check Using a Local Host Address

iR2270 / iR2870 / iR3570 / iR4570 / / / / / iR2230 / / iR3530 /
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 if the IP
address is valid.
- if the main controller PCB is faulty, replace the PCB.
If 'OK' is indicated, suspect a fault in the user's network environment. Report to the system administrator for appropriate remedial action.

2.5 Checking the Images/Operations

2.5.1 Checking the Image Quality and Operation

1) Place the Test Chart on the copyboard glass, and make copies using the individual cassettes as the source of paper; then, check the output images.
- be sure that there is no abnormal sound.
- be sure that the images are correct at all reproduction ratios.
- be sure that as many copies as specified are made normally.
2) Make settings (e.g., date, time) to suit the needs of the user.
3) Start service mode.
- press the User Mode key, press the 2 and 8 keys at the same time, press the User Mode key once again
4) Make specifications-related settings to suit the needs of the user: COPIER>OPTION>USER.
5) Make test prints by making the following selections in service mode: COPIER>FUNCTION>MISC-P>P-PRINT.
6) Put the output [1] in the Service Book case for storage.
F-2-77
7) Press the Reset key twice to stop service mode.
8) Clean up the area around the machine, and fill out the form in the Service Book.
