■ Troubles Concerning the Scanner
● Cannot connect to the scanner
When an error dialog appears when attempting to access the scanner, perform the following
checks:
1. Check whether the correct IP address of the scanner has been entered.
If the entered IP address is not correct, enter the correct one.
If the entered IP address is correct, go on to step 2.
2. From the DOS prompt run a ping test through the destination host to the IP
address of the scanner.
If the ping test fails, check whether the copier’s main power is switched on, and also check the
network cable for proper connection.
If the ping test is successful, go on to step 3.
3. Check whether the IP router is correctly set.
If it is not correctly set, set it correctly.
If there is no problem in IP router setup, go on to step 4.
4. Trace the routing to the scanner to check whether there are any error conditions
within the network.
If any error conditions are found, eliminate them.
If no error is found and yet the connection to the scanner cannot be established, contact your
service representative.
