Network Connection Problems and Remedies
The machine and cable are not properly connected.
Turn OFF the machine's power switches, check that the machine is connected
to the network using the proper cable, and then turn them ON. (See
"Connecting the Machine," on p. 2-3.)
The machine periodically or temporarily communicates with devices on your
network. If a dial-up router is on the network to which the machine is connected,
the machine connects to a destination other than the intended destination,
depending on the settings of the machine or dial-up router. This may result in
subscriber line charges and call charges.
Examples:
•
The file or mail server's host name or IP address set on the machine does not
exist on the network.
•
The DNS server exists on an external network.
•
You attempt to access a device connected to an external network, if the
device's information is set on the DNS server on the network to which the
machine is connected.
Check the following:
•
If the dial-up router does not have to send packets via broadcast, change the
router settings to ensure that it sends packets via a method other than
broadcast. If dial-up router has to send packets via broadcast, check that the
settings are correct.
•
Check that the file or mail server's host name or IP address set on the
machine is correct.
•
If you attempt to access a device on the network to which the machine is
connected, with the DNS server on an external network, set the destination
using an IP address, not a host name.
•
If information about a device on an external network is set on the DNS server
on the network to which the machine is connected, check the settings.
