Use of Web Service Function from Client Computer
Whenever it receives a request from a client computer for use of the Web Service Function, the TOE
communicates with the client computer using the SSL protocol to create a trusted path.

7.1.7.2
Printing and Faxing from Client Computer
Whenever it receives a request from a client computer for printing or transmitting faxes, the TOE
communicates with the client computer using the SSL protocol to create a trusted path.

7.1.7.3
Sending by E-mail from TOE
When sending document data by e-mail to a client computer, the TOE attaches the document data to e-mail
and sends the e-mail using S/MIME. The S/MIME destination information is registered as S/MIME user
information within general user information. Users can send e-mail referring to the registered destination
details only.
By the above, FTP_TRP.1 (Trusted path) is satisfied.
7.1.7.4
Delivering to Folders from TOE
When sending (delivering) data to folders on an SMB or FTP server, the TOE connects to the server using
the IPSec protocol to create a trusted channel. The destination information for the Deliver to Folders function
is registered in advance and managed by the TOE as machine control data. Users can send files referring to
the registered folder information only.
By the above, FTP_ITC.1 (Inter-TSF trusted channel) is satisfied.
7.1.8
SF.FAX_LINE
When it receives fax data from the telephone line, the TOE passes the data to the Controller Board. If the
received data is not fax data, the TOE discards it.
