Setting Up the Scanner
Access Control Address and Access
Control Mask
The access control address and the
access control mask are used to
limit the clients that have access to
the scanner on the basis of their IP
addresses. They are inseparable,
and therefore, if one is configured,
2
the other must also be configured
at the same time.
• The access control address uses
an IP address to set the clients
that can access the scanner.
• The access control mask is used
with the access control address
to set a range of IP addresses
that can access the scanner.
S e t t h e a d d r e s s a s f o l l o w s :
xxx.xxx.xxx.xxx (xxx: for any nu-
merical vale from 0–255)
Note
If you do not want to limit ac-
cess to the machine, use the de-
fault settings.
When the access control ad-
dress settings coincide with the
masked result of the IP address
of the computer, scanning jobs
from that client's IP address can
be accepted by the network in-
terface.
For example, if you assign
192.168.15.16 as the access con-
trol address to the Network In-
terface Board, the combination
of the access control mask and
IP Addresses that can have ac-
cess are as follows. (xxx: for any
numerical value from 0–255)

255.255.255.000 192.168. 15.xxx
255.255.255.255 192.168. 15. 16
Network Boot
This selects the way in which the
client can set the IP address of the
scanner.
The default setting is "NONE". To
change it, consult the network ad-

environment. The settings you can
