M3097DG is basically the scanner which have the duplex scanning feature with the basis of M3097G+
and with the interface compatibility to M3097G+ and M3093DG. The features of the scanner are focused
on as follows.
(1) Duplex reading
This scanner can read duplex document with one scanning to reduce the scanning workload.
(2) Excellent paper-handling
This scanner can scan various kind of the document such as the size from A3 to A6.
(3) Fast reading
This scanner scans with the following scanning speed.
Simplex, A4, 200 dpi: 36 PPM (A4,200 dpi)
Duplex, A4, 200 dpi: 60 IPM (A4,200 dpi)
(4) High quality image
This scanner reads the documents with 400 dpi basic resolution.
(5) Image processing
This scanner basically supports dither and error diffusion. Various image processing is available
when supported IPC option.
(6) New functions
Following functions are available for instance.
• Double feed detection
• Easy setting for some documents (IPC pre-setting function)
• Manual feed mode

2.6.2 Paper conditions
1) Paper type
• Woodfree paper
• PPC paper, Specified by XEROX Corporation
When using another paper, check that it is successfully fed by ADF before performing a scanning
operation.
2) Paper weight
13.9 lbs (52g/m2 ) to 27.8 lbs (104g/m2 )
3) Items to avoid
• The following documents may be hard to read by ADF.
Before you start the large quantity reading, check that the document is read appropriately. If the
ADF reading is not appropriate, read them by flatbed.
- Paper with a clip or staple
- Paper that has ink which is not dry.
- Paper thickness is not constant, such as an envelope.
- Paper that has large rumples or curl. (See Note 3)
- Paper that has folds or tears.
- Tracing paper
- Coating paper
- Carbon paper.
- Paper size that is out of standard.
- Items other than paper, such as clothes, metal sheet, or OHP film.
- Photographic paper
- Paper that has notches on its side.
- Paper that has a shape other than square.
- Paper that is very thin.
2-6
Note 1:
The important document which shall not be torn must be read by flatbed.
Note 2:
Carbon-less papers have the chemical composition which damages the pad pick roller. Therefore,
note the following remarks
Cleaning: If the miss pick occurs frequently, clean the pad and pick roller in
accordance with the Operator’s guide.
2.6 Document specifications
Replacement of parts: The life of the pad and the pick roller may be shorter than the case that PPC
document is fed.
Replacement cycle of the pad and the pick roller may be around 100,000
sheets depending on the paper quality and cleaning cycle.
Note 3:
Paper should be straightened to fit the condition below.

parameters are in affect.
*6 In IPC-3D, if Automatic Separation is specified, then Simplified Dynamic Threshold and Image
Emphasis/Smoothing are ignored.

3.2 Basic image functions
The command and data name in [ ] beneath the section title shows the location for the reference in
Appendix A.
3.2.1 Output resolution
[A.4.7 SET WINDOW command/X,Y resolution]
Selectable output resolution is shown in Table 2.3. The default is 400 dpi.
The output resolutions of 100/150/200/240/300/600 dpi are converted from 400 dpi by an electrical
method. The X direction resolution (XR) and Y direction resolution (YR) can be specified
independently. If IPC option is installed, Zooming function is available (see section 3.3.4). The
output resolution with IPC option is shown in Table 2.4.
3.2.2 Main Window Clipping
(1) Offset and Size
[A.4.7 SET WINDOW command / Upper left, Width, Length]
Offset is the length of ULX and ULY in Figure 3.1 and 3.2 with 1/1200 in unit.
It is important that the Origin point of the offset is deferent between Flatbed (FB) and ADF. When
reading with ADF, user must specify the size of the document. Then the scanner set the origin point
of that document size (X1) according to the size specified. (see Figure 3.2) If user specifies wrong
document size, unintentional offset may be given.
When specifying the offset, you must count in the mechanical offset error of the scanner as shown in
Table 3.3. You can adjust the offset with Setup mode of operator panel, scanner by scanner.

The physical limitations of the Main Window Clipping at Flatbed (FB) and ADF reading are
illustrated in Figure 3.1 and 3.2 respectively.
NOTICE: This is not the guaranteed specification but the scanner may read the long document
which fits the following condition.
i) 0 < ULY + L ≤ 33072 (@1/1200 in.)
ii) L ÷ 1200 × YR ≤ 16383 line
iii)The memory installed is enough for reading.

Image Functions
(2) Page End Detection
[A.4.11 READ command / Detected paper length]
This function cuts the reading operation when page end is detected, even if all of the window length
L (sub-scanning length) is not read yet. This function is useful to reduce the image data and increase
the throughput. When Page End Detection is set ON, the image data which is out of the page end is
deleted. (Example 2)

3.2.3 Binary reading
[A.4.7 SET WINDOW command / Image Composition = X’00’]
Following three parameters are available when binarizing the image. The 256 levels of the density at
each pixel is processed by Contrast and binarized by Threshold. When the White level following is se
ON, the white level of the CCD output follows the background of the document. So this is useful for
line art drawing but not for photograph.
