15. FAX (MFP Models Only)
Overview of FAX operations
• The FAX function sends the scanned image data from the scanner engine to the other party’s
machine via a telecommunications line as a G3 or G4 FAX. Conversely, the MFP will only accept
incoming FAX data that conforms to G3/G4 standards. The incoming document is then forwarded
on to the printer engine for printing out.
• For Internet FAX transmission, the scanned image data is sent to the DCS, where it is converted
into file attachment format for email transmission, after which it is sent to its destination via the
network I/F. Conversely, the email FAX data received as an Internet FAX is converted into image
data and then forwarded on to the printer engine for printing out.
• It is possible to store transmission files in the Document Server for sending at a later time. The file
is saved to the HDD, after which commands can be issued from the operation panel or through the
network to send the file to its destination. Conversely, incoming FAX data can be stored in the
Document Server for printing out at a later time. The incoming FAX is saved to the HDD, after which
commands can be issued from the operation panel or via the network to print out the file.
• With LAN FAX transmission, the image data received from the PC is then sent to its destination via
a telecommunications line or network I/F.
• With all FAX transmission features, including Internet FAX, it is possible to restrict individual user
access with the use of User Codes. For reception, it is possible to configure the MFP to receive
only those transmissions accompanied by a predetermined code. Operational log entries are made
for each transmission and reception job. This data is stored in non-volatile memory on the FCU,
and can be viewed by printing out the Journal.
Data Flow
• After FAX transmission is initiated, the scanning command is sent to the ECS via the FCS, and the
scanner engine is activated. At the same time, the data retrieval and transmission commands are
sent to the FCU via the FCUH. The image data in memory is then sent from the scanning engine to
the FCU, after which it is sent to its destination via the telecommunications line.
