2.6.2 Paper Conditions1) Paper type

• Woodfree paper

• PPC paper, Specified by XEROX Corporation

When using another paper, check that it is successfully fed by ADF beforeperforming 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 theADF 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.

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 and pick roller. Therefore,note the following remarks

Cleaning: If the miss pick occurs frequently, clean the pad and pick roller in accordance with theOperator’s guide.


2-8

Replacement of parts: The life of the pad and the pick roller may be shorter than the case that PPCdocument is fed.

Replacement cycle of the pad and the pick roller may be around 100,000 sheets depending on the paperquality and cleaning cycle.

Note 3:

Paper should be straightened to fit the condition below.

3.2.4 Halftone readingThis scanner supports two types of halftone image, that is Dither and Error Diffusion.

NOTICE: The density of the halftone can not be adjusted by the Threshold in Table 3.4 but theBrightness in Table 3.5.

(1) Dither

This is a way of producing halftone images with white and black pixels. The scanned image isprocessed by the unit of group of pixels.

At first a reference table called “dither matrix” is specified. Each element in the matrix (8x8)has a threshold value of 256 levels. Allocation of threshold values in the dither matrix is called“dither pattern”. Group of the scanned images are compared with the dither pattern, and eachelement is decided whether it is black or white. Number of black pixels corresponds to a levelof scale, producing pseudo grayscale images.

Four built-in dither patterns are available. Parameters which affect dither are shown in Table3.7.

(2) Error diffusion

This is a way of producing halftone (Pseudo grayscale) images with white and black pixels.Optical density of pixels and its adjacent pixels are totaled and black pixels are repositioned inthe order of density in accordance with relations between adjacent pixels.

This scheme aims to minimize errors between scanned density and printed density on theaverage. Density data of adjacent pixels are modified by diffusing errors on the objective pixelinto several pixels to be binarized. This scheme is aimed to keep high levels of grayscale andhigh resolution, producing high quality halftone. Especially when dotted halftone images likephotos on the newspaper are scanned, this scheme suppresses moire patterns.

Following parameters are available for this function

The parameters which affects the Halftone image are shown in Table 3.8.

The name of command and register in [ ] beneath the section title show where the item is specified inAppendix A.

3.3.1 DTC mode function (Auto I mode)[A.3.3.2 CONTROL command / Control register ]

This mode is designed to scan for better image quality to provide OCR (Optical Character Reader).Threshold algorithm was developed to capture important text features for recognition purpose. Theimage processing is deferent between IPC-2D and IPC-3D as follows.

IPC-2D : Note that the DTC image processing is composed by the following sub-functions.

3.3 Optional image function

IPC-3D: Dynamic Threshold is identical to the Simplified Dynamic Threshold in IPC mode.

(See section 3.3.2)

NOTICE 1: Threshold, Brightness, and Contrast settings are ignored in DTC mode.

NOTICE 2: Gamma correction is also ignored in DTC mode.

(1) Pre-filter

The pre-filter performs filtering before processing the Dynamic Threshold. Ordinary and Ball-point Pen are selectable in Pre-filter.

Linear gamma curve Ordinary

Use Ordinary basically. For the texts written by ball-point pens, use of Ball-point Pen may betterfor OCR. This is because, the texts written by ball-point pens actually have two thin lines perstroke. To human eye, this is not big problem, but OCR may not recognize the text. The Ball-pointPen filter detects lighter areas compared to the surroundings and increases the density of thelighter area. puts these two lines into one solid line. This can prevents cuts, void or too thin lines.

(2) Gradation

Gradation specifies the gamma curve correction before processing Dynamic Threshold. Whenscanning news papers or old documents which background is dark, it is desirable that the gammacurve has coarse steps in the lighter side and fine steps in the darker side. This is called HighContrast gamma curve.

(3) Dynamic Threshold Curve

For the Dynamic Threshold function, the threshold is changed with the average optical density ofa small area (e.g. 5x5 pixel area).

Relation between the threshold and maximum density is formed as a curve when the threshold isexpressed in the Y-axis and the maximum density in the X-axis. This curve is called “thresholdcurve”.

Image Functions

3-16

This function allows a customer to select a threshold curve. Several different curves are prepared, one isthe OCR type and other is the image type. The characteristic of the curve is deferent between IPC-2D andIPC-3D.

IPC-2D: The image type curve has steeper inclination in the middle of the curve. For OCR typecurve, the customer can select type (inclination) and density level.

PC-3D: 8 curves are available which adjusts the sensitivity of the image

IPC-3D:IPC-2 like Simplified DynamicThreshold

When Image Emphasis is specified

a) Simplified Dynamic Threshold

The Simplified Dynamic Threshold is effective to obtain sharp images or capture texts havingcolored backgrounds. This effect is similar to Image Emphasis. The difference is that theSimplified Dynamic Threshold does not emphasis the background. This is useful for forms,checks and most real world document.In IPC mode, Simplified Dynamic Threshold was asimplified implementation of the Dynamic threshold. In IPC-2D, Simplified DynamicThreshold is no simpler, but sometimes more effective than Dynamic Threshold forbackground texts. In IPC-3D, both Dynamic Threshold are the same and sophisticated.

b) IPC2 like Simplified Dynamic Threshold

IPC-3D supports IPC-2 like Simplified Dynamic Threshold for compatibility purpose. Whenboth Image Emphasis and Simplified Dynamic Threshold are set, it is regarded as IPC-2 likeSimplified Dynamic Threshold. In this case, IPC-3D Sensitivity parameters in SimplifiedDynamic Threshold are used as the Variance Rate, and Image Emphasis parameters are usedfor emphasis. The IPC-2 like Simplified Dynamic Threshold increases resolution.

(2) Image Emphasis

Image Emphasis performs filtering to emphasize image edges or to smooth (IPC-2D) orremove background noise (IPC-3D). If text edges are not clear or faint, turn on the ImageEmphasis. Three levels of Image Emphasis, High/Mid/Low, are available. As a side effect,Image Emphasis also emphasizes the noise. It is better to set Image Emphasis higher to obtaingood image, until the noise is not perceptible.

In IPC-2D, Smooth is also available which works as negative emphasis so image edgesbecomes faint even if original is ordinary sharp.

In IPC-3D, Background Removal is available instead of Smooth. Background Removal iseffective to remove background tones. For the case of the texts surrounded by halftone patternsuch as dither, background should be removed to emphasize the text. Background is useful forsuch cases.

The algorithm of Smooth and Background Removal is deferent but the outputs are similar.

A.3 Commands and Response

A.3.1 Basic Command/Response SequenceData is transmitted between the host computer and the image scanner in the form of commands andresponses. Figure A.3.1 shows the basic command/response sequence. In Figure A.3.1, “Other thanACK” means a parity, flaming, overrun, or count error.


Appendix A-17

Notes:

1. Abnormal reception means that a parity error, flaming error, overrun error, or count error has occurred.

2. Command or response transmission is retried only twice.

3. Upon reception, a command or response is checked for transmission errors. When the check result has noproblem, ACK is returned immediately to the originating source. When the check result has problem, dataother than ACK is returned after all data has been received.

4. The originating source of the command/response monitors the response from the receiving side. ACKindicates that command/response transmission is completed. Data other than ACK causes thecommand/response to be transmitted again. The transmission is retried only twice. After that, the scannerwaits for a new command.

5. Response data such as ACK must be returned to the originating source within 0.5 second.

6. The interval between words in the data steam must be no more than 10 ms.

7. Response of the CLEAR command must be less than one minute.Figure A.3.1 Basic command/response sequence

Image control register

When the image processing option (IPC-2D or IPC-3D) is connected, the following image processing canbe executed. This register sets the image processing mode.

- Image area automatic separation function (simultaneous reading of characters and photographs)

- Inversion function (black/white conversion)

- Mirror image output function (right/left conversion)

- Image emphasis, outline extraction function

- Overlay function

- Symplified dynamic threshold

- Zooming function ranging from 25% to 400% in 1% increments. (*1)(Max. 800 dpi)

- Function to change the reading mode of a section in the main window (subwindow function) (*2)

The method of image processing can be separately specified for the main window and subwindow unlessotherwise specified.

*1 Same zooming rate is applied both front-side and back-side reading.

*2 This function is executed by the subwindow control command described later.

*1 The subwindow control register is valid when the subwindow is valid.

*2 Halftone specification (control register A#2/B#2) is invalid in the automatic separation mode.However halftone processing (dither or error diffusion) for photo area follows control registerA#19/B#19, and the dither pattern follows control register A#2/B#2.

(f) Image control register A#5 and A#6

*1 Registers A#5 and A#6 must be sent consecutively. Registers A#5, A#6, A#7, and A#8 must besent consecutively for different vertical/horizontal magnification.

*2 When both sides of documents are scanned and magnified in the sub-scanning direction, thefollowing limitations exist:

1) B x (C/100) < 800

When a resolution exceeding 800 dpi is specified for scanning, an operation error occurs(800 dpi is the maximum allowable resolution).

*3 When the vertical/horizontal zooming specification is set to “0”, the horizontal and verticalmagnification is indicated. When this specification is set to “1”, vertical magnification isspecified at bit 0 of the register #5 and at all bits of the register #6.

X’0864’ is set when the power is turned on or when the initial status is specified.

ExampleHow to calculate the output resolution :

• Control register #1 is X’0B’ (200 dpi)• Image control register #5 and #6 are X’0819’ (25%)

Output resolution = 200 dpi x 0.25 = 50 dpi
