expected. Moreover, the matters expected to occur in the use environment are listed below.
Office
IC Card
SMTP Server
TOE
DNS Server
Internet
Firewall
External Network
Intra-office LAN
Public line
IC Card
Client PC
MFP
Active Directory Server
IC Card reader
Figure 1 An example of MFP’s use environments
An intra-office LAN exists as a network in the office.
MFP is connected to the client PCs via the intra-office LAN, and has mutual data
communications.
An IC card and an IC card reader of the client PC is used to transmit the encrypted print file
to MFP using the exclusive printer driver and decrypt the scanned image data transmitted
from MFP.
Active Directory sever is connected to an intra-office LAN and it is used to the authentication
of IC card.
When a SMTP server is connected to the intra-office LAN, MFP can carry out data
communication with these servers, too. (The DNS service will be necessary when setting a
domain name of the SMTP server)
When the intra-office LAN connects to an external network, measures such as connecting via
a firewall are taken, and an appropriate setup to block access requests to the MFP from the
external network is applied.
The public line connected with MFP is used for communications by FAX.
