Troubleshooting
• 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.
Detailed information concerning the machine cannot be set or browsed using a web browser (Remote UI),
or utility.
Cause 1 The IP addresses of computers on which a web browser (Remote UI) or utility is used are not
allowed in <Setting/Browsing Range> in [IP Address Range Settings].
Remedy If the settings for <Setting/Browsing Range> in [IP Address Range Settings] do not permit
the IP address of a computer on which a web browser (Remote UI) or utility is used, you
cannot set the machine setting items or browse information on the machine.
Check the settings for <Setting/Browsing Range> in [IP Address Range Settings]. (See step
21 in "TCP/IP Settings," on p. 3-4.)
Cause 2 [Use SNMP] or [Enable Dedicated Port Settings] is set to [Off].
Remedy Set [Use SNMP] and [Enable Dedicated Port Settings] to [On]. (See "Communication
Environment Setup," on p. 2-17.)
Cause 3 The SNMP community name does not match.
Remedy If you use an SNMP community name different from that stored in the machine to access the
machine from a utility, the utility will not detect the machine. In this case, check the SNMP
community name. (See "Communication Environment Setup," on p. 2-17.)
