If the quick IP filtering function is used, the range of IP addresses for which access is to be restricted
is specified automatically. To manually specify the range of IP addresses for which access is to be re-
stricted, set [Network] - [TCP/IP Setting]-[IPv4 Filtering] or [IPv6 Filtering] instead of using [Quick IP Fil-
tering].
Settings Description
[Quick IP Filtering] Allows you to restrict the devices that can access this machine using the IP ad-
dress (IPv4/IPv6). The range of IP addresses for which access is to be restrict-
ed is specified automatically.
•
[Synchronize IP Address]: For the IPv4 address, this option only permits
access for the IPv4 address set to this machine, and the IPv4 addresses of
which the high-order 3 bytes are the same.
Example: When the IPv4 address of this machine is set to "192.168.0.134",
the range of IPv4 addresses that allow access is as follows.
192.168.0.0 to 192.168.0.255
For the IPv6 address, this option only permits access for the global unicast
address (2000::/3). Also, this option only permits access for the IPv6 ad-
dress set to this machine, and the IPv6 addresses of which the high-order
64 bits are the same.
Example: When the IPv6 address of this machine is set to
"2345:1:2:3:4:5:6:7", the range of IPv6 addresses that allow access is as
follows.
2345:1:2:3::0 to 2345:1:2:3:FFFF:FFFF:FFFF:FFFF
• [Synchronize Subnet Mask]: For the IPv4 address, this option only permits
access for IPv4 addresses that belong to the same network using the IPv4
address set to this machine and subnet mask.
If no subnet mask is set or "0.0.0.0" is specified, this option permits the
IPv4 address set to this machine, and the IPv4 addresses each of which
only the suffix is different. This results in the same operation as for [Syn-
chronize IP Address].
Example: When the IPv4 address of this machine is set to
"192.168.17.134" and the subnet mask is set to "255.255.252.0", the range
of IPv4 addresses that allow access is as follows.
192.168.16.*** to 192.168.19.***
For the IPv6 address, this option only permits access for the global unicast
address (2000::/3). Also, filtering is carried out using the global IPv6 ad-
dress set to this machine and prefix.
If the prefix is not specified, filtering is carried out in the same way as when
the 64-bit prefix is specified.
Example: When the IPv6 address of this machine is set to
"2345:1:2:3:4:5:6:7" and Prefix is set to "/64", the range of IPv6 addresses
that allow access is as follows.
2345:1:2:3::0 to 2345:1:2:3:FFFF:FFFF:FFFF:FFFF
• [No Filtering]: Does not use the filtering function.
[No Filtering] is specified by default.
[Security Warning Dis-
play Setting] Select whether to display the security warning screen if the administrator pass-
word remains set to the default or if password rules are not satisfied.
[OFF] is specified by default.
[USB Enable Settings] Specify whether to permit a function that requires the USB Port .
• [Save Document]: Select whether to enable to save files on USB memory.
This function is available when [Individual Settings] is selected in [Security]
- [USB Connection Permission setting] - [External Memory (User)] in the ad-
ministrator mode. [Restrict] is specified by default.
• [Print Document]: Select whether to enable to print files from USB memory.
This function is available when [Individual Settings] is selected in [Security]
- [USB Connection Permission setting] - [External Memory (User)] in the ad-
ministrator mode. [Allow] is specified by default.
• [External Memory Document Scan]: Select whether to enable to save files
scanned from USB memory into a User Box. This function is available when
[Individual Settings] is selected in [Security] - [USB Connection Permission
setting] - [External Memory (User)] in the administrator mode. [Restrict] is
specified by default.
• [Print]: Select whether to enable to print files from a USB-connected com-
puter. This function is available when [Individual Settings] is selected in [Se-
curity] - [USB Connection Permission setting] - [PC Connect] in the
administrator mode. [Allow] is specified by default.
