Network Connection Problems and Remedies
This section describes the causes of network connection problems, and how to
resolve them.
Unable to Set up a Network
Cause [Change Settings/Display Connection Confirm.] is set to 'Off'.
Remedy Set [Change Settings/Display Connection Confirm.] to 'On'.
<Check the network connection.> is displayed on the control panel.
Cause 1 The machine and cable are not properly connected.
Remedy 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 to a Computer or Network," on p. 2-3.)
Cause 2 [Change Settings/Display Connection Confirm.] is set to 'On', although the
machine is not connected to a network.
Remedy Set [Change Settings/Display Connection Confirm.] to 'Off'.
The machine automatically connects to a destination other than the intended destination via
its dial-up access (when a dial-up router is connected to your network).
Cause The machine periodically or temporarily communicates with devices on your
network. If a dial-up router or NetWare file server 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.
