Problems with Connections
Cannot set up the network.
● Check whether <Confirm Network Connection Setting Changes> is set to <On>.
<Confirm Network Connection Setting Changes>(P. 741)
An unintended destination is dialed up.
● 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. 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 it is necessary to allow broadcasting with the
dial-up router, check whether an unnecessary destination is set.
● Check whether the host name and IP address of the file server and mail server, etc. set in the machine are
correct.
● If the DNS server is on an external server, use the IP address instead of the host name for the destination,
even when connecting to devices on the same network as the machine.
● If the DNS server is on the network that the machine is connected to, check whether the information for
devices connected to an external network is registered on the DNS server, and whether it is correct.
Cannot recognize the machine from a computer.
● If the IP address of the computer where the Remote UI and utility software are executed is not allowed for
sending and receiving in <Firewall Settings>, the information for the machine cannot be displayed on the
computer. Check whether the settings are correct.
Specifying IP Addresses in Firewall Settings(P. 597)
● When using Canon software such as iW Management Console, set <Set Dedicated Community> to <On>,
and select <Read/Write> for <MIB Access Permission>. Also set <Dedicated Port Settings> to <On>.
Monitoring and Controlling via SNMP(P. 53)
● The machine cannot be recognized when utility software is used to access the machine with a community
name other than the SNMP community name set in the machine. Check the SNMP community name.
Monitoring and Controlling via SNMP(P. 53)
● If the message "An error has occurred." is displayed in the Web browser and the Remote UI cannot be
started, invalid cache data may remain. Clear the cache of the Web browser.
● If the machine enters the Sleep mode, it may not be able to be recognized from a computer. Press to
cancel the Sleep mode or change <Sleep Mode Energy Use> to <High>.
