1.1 General
M3097G image scanners produce excellent electronic images from documents using
the high quality optical image scanning technology and output to the host system.
The M3097G can scan a single page (including a page of a book) of a double>letter
size (17 in.¥11 in.) or A3 size (420 mm¥297mm) in maximum on the standard flat>
bed. The M3097G has an Automatic Document Feeder (ADF) that can
accommodate up to 100 pages.
The M3097G outputs only binary data on the Small Computer System Interface
(SCSI).
Figure 1.1 shows outer view of this scanner.

1.2 Features
(1) Fast reading
This scanner can read data about twice as fast as the M3096G.
For flatbed reading: 1.3 seconds (A4, 200 dpi) (M3096G: 2.3 seconds)
For ADF reading: 36 pages per minute (A4, 200 dpi) (M3096G: 18 pages per
minute)
(2) Large
>capacity document feeder
Up to 100 pages (A4, 55>kg continuous forms) can be loaded into the document
feeder. (M3096G: Up to 50 pages)
(3) High
>quality image
This scanner uses a compact optical system that provides sharper focus.
Furthermore, the use of new LSI chips produces finer images.
(4) New image processing
The standard version of this scanner has error diffusion function. Dithering or error
diffusion can be applied to those areas judged to be photographs by automatic
separation (image processing ¬ option).
(5) Compact
This scanner is small and light. (Its size is almost the same as that of the M3096G)

2.3 Optional Circuit Feature
The following option is provided for this scanner:
f Image processing circuit ¬ (M3097E0191)
For the details, refer to Subsection 2.3.1.
f CMP II (M3097G0196)
2.3.1 Image processing circuit ¬ (IPC ¬)
This option has the dynamic threshold function and image processing function.
2.3.1.1 Dynamic threshold function
The main purpose of this function is to read handwritten characters.
Handwritten character recognition preprocessing invalues specifying required
values for threshold curve setting, smoothing mode, and filtering mode.
Noise removal reduces noise often found in images after dynamic threshold
processing.
Threshold curve setting, smoothing mode, filtering mode, and noise removal are all
dynamic threshold circuit (DTC) functions.
(1) Threshold curve setting
The contrast level of the dynamic threshold circuit can be changed with setting 3
bits (8 levels).
(2) Smoothing mode
The convex portion of the segment is removed and the concave portion is filled up to
smooth the segment.
(3) Filtering mode
(a) Ball>point pen mode
This mode is used when this scanner is used as the input device of OCR system.
When using writing materials caused inter>ommission, e.g. ball>point pen, the
density of the omission portion is increased according to the density of
surrounding portion to get the picture does not have inter>omission.
(b) Normal mode
This mode is used when using writing materials other than above.
(4) Noise removal
Among black>dots in the binary picture code, the black>dot for the noise is changed
to white>dot.

1 Automatic separation
Line>drawing/Photo
( )
automatic separation
Recognizes the photo area and Line>drawing
area in one scanning automatically, and outputs
data with applying dither processing or error
diffusion for the photo and the binarizing for the
line>drawing.
2 Outline extraction Extracts the outline of the Line>drawing such as
a thick character.
3 Image emphasis Emphasizes the black>white contrast to raise the
contrast.
4 Overlay (*1) Overlays the pattern on the scanned data and
make the overlayed black data to white data.
5 Reverse image
(White/black conversion)
Converts white into black and black into white
of read data (binary data).
6 Mirror image Turns over the both sides of read data.
7 Simplified dynamic
threshold
Changes the slice level of the binarizing
according to the density of the document.
8 Zooming Magnifies or reduces the image data in the range
between 25% and 400% with 1% step.
9 Subwindow 4 Subwindow can be specified on Main window.
The functions above are all image processing circuit (IPC) functions.

This image scanner and the host are connected via an 8>bit parallel interface. The interface
follows the ANSI (American National Standards Institute) SCSI 2 (Small Computer System
Interface 2) Revision 10c.
This chapter provides an overview of SCSI (minimum information necessary for
understanding this scanner), as well as descriptions peculiar to the scanner. For details of
SCSI, refer to the ANSI standard.
The following terms are needed to understand this section.
f SCSI device: A host adapter or a target controller that can be attached to the SCSI
bus
f Initiator: An SCSI device (usually a host system) that requests an I/O process to be
performed by another SCSI device (a target)
f Target: An SCSI device that performs an operation requested by an initiator
f Logical unit: A physical or virtual peripheral device that is addressable through a
target
Range of support
(1) System configuration
This scanner operates under the multiinitiator, multitarget environment. An
initiator function is not provided. This scanner incorporates an integrated target
and logical unit (image scanner).
