CHAPTER 1 GENERAL
1.1 General Description
1.2 Features
1.1 General Description
M3097E image scanners are compact, inexpensive, and ideal input devices for
electronic filing systems, facsimiles, optical character readers (OCR), computer
aided design (CAD) systems, and automatic publishing systems.
The M3097E can scan double>letter or A3 size paper. The M3097E has an
automatic document feeder (ADF) that can accommodate up to 100 pages.

1.2 Features
(1) Fast reading
This scanner can read data about twice as fast as the M3096E+.
For flatbed reading: 1.3 seconds (A4, 200 dpi) (M3096E+: 2.3 seconds)
For ADF reading: 36 pages per minute (A4, 200 dpi) (M3096E+: 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. (M3096E+: 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
M3096E+)

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.
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.
The dynamic threshold circuit is selected when control register #1 bit 4 is set to 1 or
DENSITY is set to AUTO 1 on the operator panel.
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.
2 $ 4 50FH5037E>02
(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.

No. Function name Details function
1 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 resolution.
4 Overlay Overlays the pattern on the scanned data and
make the overlayed black data to white data.
5 Inversion
(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 document in the range
between 25% and 400% with 1% step. Also
reads the document with different
magnification in horizontal and vertical
scanning.
9 Subwindow 4 Subwindow can be specified on Main window.
The functions above are all image processing circuit (IPC) functions.
