1 Description of the Scanner Options

1.1 Introduction

This documentation is valid for the following scanners of the company InoTec:

• Scamax 2600 / Scamax 2500

• Scamax 5000

You must use the following driver: jukscsi

The scanner is connected using a standard SCSI interface board, and an ASPI driver must be installed.

This program module was developed to enable the user to set the special options of the Admis S31 scanner. The jukscsi driver from Janich & Klass forwards these settings to the scanner.

The special scanner settings are offered with the user interface, spread over several pages.

2 Device Properties

The first page gives setting possibilities for double feed detection, length control, manual feeding mode, and fill color options.

Illustration 1 – Inotec Properties Tab: Device

Double Feed Detection

Standard Scamax Series document scanners are equipped with an ultrasonic double feed sensor. The sensor is active during the entire scanning process (over the complete length of the document) and gives an error report in the case of a double feed.

The following modes are available for double feed detection:

Active

Double feed detection is enabled.

Inactive

Double feed detection is disabled.

Only Start of Document (5cm)

The ultrasound sensor is active only for the first two inches of each original. Labels, Post-It Notes, or other stickers that are not placed on top of the sheet, but at least two inches lower the top, will not cause a double feed error message to appear.

Page 6 of 42

Scanner Options Scamax 2600 / 5000 DpuScan

After Start of Document (5cm)

The ultrasound sensor becomes active only after the first two inches of each original. In batches with different document types and very thin originals, a second sheet may feed too deeply into the scanner, causing the sensor to report an error even though only one sheet was fed and scanned.

In this mode, the above-mentioned event is unlikely to occur.

Reduced

The sensor will react only after a certain length of a detected double feed. These lengths depend on the set paper size. Smaller stickers and labels do not automatically lead to a double feed error message.

No Length Control

Normally, the scanner will use the length of the set paper size (paper format) in order to determine when a sheet reaches its end. If the camera still captures paper after the defined paper length, it may be caused by a document that is too long (larger than the set paper format), a staggered double feed, or an extreme skew of the document. In such a case, the device will report an error.

On the other hand, if the paper is shorter than the expected format, the device will continue to scan until enough image lines come together to result in an image of the desired format length. The additional images lines are usually displayed in black. It is not filled up mathematically, so that the Fill Color function has no influence here. Only when the image is complete will the next document feed through the scanner. Thus, scanning a smaller original document will take the same amount of time that it takes to scan an original with the defined paper format. The Deskew and Cropping functions can be enabled.

If the length control is disabled (its box is checked), the device will scan in the defined paper format length at a maximum, without regard as to whether the original is longer. Documents over this defined length will be cut to match the defined format length (eventually creating an information loss) and the double feed detection by paper length control will not be active. If, however, the paper is shorter than the defined format length, the scanner will fill up the rest of the image mathematically to meet the defined format length using the function Fillcolor on overlength. When the paper is shorter than expected, there will be a gain in speed, because the next original is immediately fed and scanned after the smaller original document.

Manually

Delayed feeder-empty-message for hand feeding

A sensor is located at the paper feeder of the scanner that reports "no paper" or "paper available" to the scan application. If a paper batch is scanned and the last sheet is fed, the sensor reports "no paper" to the software. The feeder rollers will then stand still and are reactivated only when new paper is fed and a new scan command is given by the scan application.

If originals cannot be processed from the batch, it is possible to switch the scanner to manual feed by means of the Manually function. Then, the scanner will no longer report "no paper" to the scan application until there is a timeout of eight seconds. During this time, the feeder rollers continue rolling, allowing fast and efficient scanning with the manual feeder.

DpuScan Scamax 2600 / 5000 Scanner Options

Please make sure the single sheet processor is switched on at the scanner.

Another possibility to effectively work with the manual feeder is the "Ignore paper status" function on the Options property tab.

Fillcolor on Underlength

This parameter determines the fill color with which the missing length of an image that is shorter than the defined paper length. This function can be executed only if "No Length Control" is enabled and if the borders of the image are not cut. (Function: Border Cropping).

With a duplex scanner, this fill color is valid for the front side of a document and the back side.

Fillcolor on Deskew

This parameter determines the fill color for missing parts of an image due to a document skew and automatic alignment.

With a duplex scanner, this fill color is valid for the front side of a document and the back side.

Roller Cleaning

The transport rolls of the machine should always be cleaned when the scanner no longer feeds the paper from the batch.

To clean the rollers, take a fluff-free cloth or piece of paper and use the recommended cleaning liquid. After starting the process, press the cloth to the underside of the feed rollers.

After pressing the Roller Cleaning button, a dialog appears that allows the user to start and stop the process.

White Calibration

White calibration is required to compensate for differences in brightness that arise in the optical transmission system. The calibration is made at the factory site, but it is also recommended in situations when:

• a new lamp has been mounted in the scanner, or

• there are "stripes” and differences in brightness that are not caused by normal pollution of the

machine during the production process. Please make sure to clean the scanner before starting any calibration.

The calibration is best made with the special white calibration sheets that were shipped together with the machine. Put the calibration sheet into the feeder and press the calibration button.

Another dialog appears to start the process.

The process cannot be interrupted, and takes about ninety seconds to complete.

When the calibration is completed, a corresponding message dialog appears. Please restart the scanner after every white calibration.

3 Image Processing Options

To optimize image quality you can set different image processing parameters. They are offered on the next two pages, separately for Front and Back camera.

Illustration 2 – Inotec Options: Front Page

Binarization Method

The binarization method defines how the 256 possible grayscale values that come from the camera will be transformed into bitonal information (black and/or white pixels).

Fixed Threshold

One of the 256 grayscale values is defined as the fixed threshold for the brightness. All levels above will be represented as ”white”, and all others will be represented as ”black”. This simple method is suited for "normal" documents without special colors, stains, or bad print.

Recommended Value: Brightness = 165

Automatic Threshold (one-dimensional)

The changes in gray levels in one line of the image are used to decide what is black and what is white.

When deciding black or white, the scanner considers the previously read values of an image line. Depending on the contrast settings, deviation levels in the grayscale values are considered for the black/white decision dynamically.

Recommended Value: Brightness = 165; Contrast = 4

Page 9 of 42

DpuScan Scamax 2600 / 5000 Scanner Options

DTplus Threshold (two-dimensional)

If the scanner has the DTplus board (optional), several image lines can be considered for the black/white decision. As with the Automatic Threshold, not only the value itself, but also deviations in its surroundings are considered.

The setting for brightness serves as the threshold for areas, and the setting for Contrast as the sensitivity level for graylevel differences.

Recommended Values: Brightness = 165; Contrast = 12

Contrast

The contrast value defines the sensitivity for graylevel changes at neighboring pixels that will lead to an interpretation of black or white. The lower the contrast, the higher the sensitivity level of the scanner for graylevel changes.

For the automatic threshold, the Contrast can be set in 8 levels of sensitivity

Recommended Value = 4

If the device features a DTplus board, the two-dimensional DTplus threshold can also be used. Here, 127 theoretical sensitivity levels are available, but sensible settings are in the range between 5 and 25

Recommended Value = 12

Brightness

The brightness can be freely selected between values of 0 to 255. This represents the 256 graylevels that the camera can capture. Sensible settings lie, as per the threshold method, between the values of 120 and 180.

With the binarization method "Fixed Threshold", the brightness assumes a graylevel value between 0 and 255 as the limit from where the scan result for a pixel will be white or black.

Recommended Value = 165.

With the "Automatic Threshold", the brightness only serves as a threshold for the start value (white or black) of every scan line.

Recommended Value = 165

With the binarization method "DTplus Threshold", the setting for brightness controls represents which gray value will be represented as black or as white.

Recommended Value = 165

DTplus Filter

With the DTplus option, filters are available to reduce unwanted pixel "noise". The filter deletes black and white pixels (despeck function) immediately after scanning, and even before the image is saved. The table below lists the 60 possible values for the filter. With the value of 0, pixels will not be filtered out at all. With the value of 1, black specks of 1x1 pixel are deleted. With the value of 16, black specks of 4x2 pixels size are deleted, and all white specks of 1x1 pixel size (within black areas) are filled with black.

Tracker for Brightness

W / 1x1 W / 2x2

W /

W / 1x1 W / 2x2

This tracker can be enabled only if the scanner is equipped with a DTplus board.

The DTplus board also works with a background tracker. It calculates the gray value of the background, using several scan lines.

When enabling the "Use Tracker for Brightness" function, the brightness is adjusted to the gray value of the background, as evaluated by the background tracker, and is reregulated continuously during several scan lines. This dynamic adjustment of brightness should be added for mixed documents if their backgrounds have distinctly different colors (white, green, rose, gray, blue, etc.).

Tracker for Contrast

This tracker can be enabled only if the scanner is equipped with a DTplus board.

The DTplus board also works with a background tracker. It calculates the gray value of the background, using several scan lines.

When enabling the "Use Tracker for Contrast" function, the contrast value is dynamically reregulated with more sensitivity. The darker the gray value of the background has been calculated by the background tracker, the lower the value. Because black text on a dark background results in a lower gray value difference, the scanner will react more sensitively in this case. As with the "Use Tracker for Brightness” function, this function is advised for mixed document batches with distinctly different background colors.

Mode

The mode is a combination of all settings made for Patchcode recognition, for counter behavior, for endorser output, and for the rules to control the counters. This option allows the user to select from one of the 16 operating modes.

To load, to change, and to save a mode, the user has to use the module Patchcode Controlled

Index, which you can reach by pressing the Configuration button.

Confirm

The driver permanently stores the counter positions. This way, they can be used continuously, as well as after longer breaks. Use the following dialog to confirm the current counter position, which you can reach by clicking the Counters button. The dropdown list allows you to determine when this dialog shall display automatically:

• Never

• On every scan job start

• Only after an error occurs
