Detailed information concerning the machine cannot be set or browsed using the Remote UI
or utility.
Cause 1 The IP addresses of computers on which the 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 the 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 22 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. 2-12.)
Cause 3 The SNMP community name does not match.
Remedy If you use an SNMP community name different from the one 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. 2-12.)
