14. Scanner (MFP Models Only)
Overview of Scanner Operations
• Depending on the settings selected, the Scanner function does one of the following:
1) Saves the scanned image to the HDD and then sends it via the network I/F as an email (via an
SMTP server), to a folder (FTP server, client PC with Windows 98 or newer), or forwarding server
(via ScanRouter),
2) Saves the scanned image to the HDD alone without forwarding it, or
3) Temporarily stores the image to the HDD and then forwards it to one of the destinations
mentioned above.
With the third option, the page location data for the data temporarily stored to the HDD is deleted
once the destination receives the transmission, or after the maximum number of transmission
attempts has been reached.
• With the TWAIN I/F, the TWAIN driver can initiate a scanning job under specified conditions from a
network-connected client PC, after which the image is sent back to the TWAIN driver.
• Access to the Scanner function itself or to specific features can be restricted with the use of User
Authentication, the Available Functions settings for each individual user, and an external coin/card
operated device. Use of the TWAIN feature is only allowed after a crosscheck with the User Code,
User ID and password pre-programmed in the TWAIN driver U/I.
• Operational log entries are created for both scanning and forwarding jobs. The forwarding results
can be printed out or viewed directly from the operation panel (“Scanned File Status”). These
results are stored in non-volatile memory, i.e. the data is preserved even after the MFP main power
is turned off.
Data Flow
• The raw image data sent to the RAM managed by the IMH goes through MH/MR/MMR/JPEG
compression or is left uncompressed, depending on the operator’s settings. TIFF headers are
attached to all data except JPEG-compressed files. The data is then sent over the network in a
commonly used image file format. In addition, it is also possible to convert these files to multi-TIFF
or PDF format before they are sent.
