Starting the Scan

Validation Tool

The Kodak i4250, i4650 and i4850 Scanners provide the ability to process scanned images to improve their quality by using image processing features.

Image processing refers to features of the scanner that allow you to automatically adjust each image that may improve the resulting images (e.g., correcting any skew in the fed document, cutting the edges of the image off to remove unneeded borders or cleaning up extraneous “noise” on the image).

The information in this guide provides procedures for using the TWAIN Datasource as well as descriptions of the features. The same features should be available on the user interface of the scanning application you are using (e.g., Kodak Capture Pro Software).

1.Select Start>Programs>Kodak>Document Imaging>Scan Validation Tool.

2.Select TWAIN for the Driver Type and the KODAK Scanner i4x50 as the driver.

The Scan Validation Tool dialog box will be displayed.

The Scan Validation Tool dialog box

The Scan Validation Tool (SVT) is a diagnostic application provided by Kodak Alaris. The SVT user interface allows access to all the features of the scanner and is a good way to verify that the scanner is working properly. The Scan Validation Tool allows you to verify scanner functionality using the TWAIN Datasource.

NOTE: The Scan Validation Tool is not intended to be used as a production scanning application. There are many full featured applications that support the Kodak i4x50 Scanners. The Kodak Capture Pro Software Limited Edition scanning application that is included with this scanner is a good choice for basic scanning. Kodak Capture Pro Software Limited Edition can be upgraded to the full version of Kodak Capture Pro Software as your scanning needs increase.

TWAIN Settings screen When you click the TWAIN Settings icon the following screen is displayed.

Transfer Type (ICAP_XFERMECH) — allows you to select which

TWAIN transfer type to use.

•File (TWSX_FILE): the driver saves the image directly to a file. SVT reads the image from that file for display.

•Memory (TWSX_MEMORY): the driver transfers the image into memory created by SVT.

•Native (TWSX_NATIVE): the driver transfers an uncompressed bitmap representation of the image into memory created by the driver and then the memory ownership is given to SVT.

Files To Save

Images — when selected, scanned images will be saved to the specified Destination directory with the specified Destination prefix.

NOTE: This is not available for Transfer Type - File (TWSX_FILE).

Image information (DAT_EXTIMAGEINFO) — the information is saved in a .xml file. The file will be saved to the specified Destination directory with the specified Destination prefix and with the associated image number.

•(none): no image information is saved.

•All: all image information will be saved.

•Only barcode data: just barcode related image information will be saved.

Using the TWAIN

Datasource

Driver User Interface When Scanning

Show setup with scan button (TW_USERINTERFACE.ShowUI) — displays the Main screen of the TWAIN datasource when a scan is initiated.

NOTES:

•Scanning will not start until the Scan button is selected on the Scan Validation Tool dialog box.

•All error and progress messages will be displayed.

Display progress (CAP_INDICATORS) — displays any error and progress messages during scanning.

Automatically feed each sheet of paper (CAP_AUTOSCAN) — during scanning, each document will automatically be scanned; otherwise, the user decides when the scanner will scan the next document (i.e., by using the Scan One Page button).

OK — saves any changes and closes the TWAIN Settings dialog box.

The Kodak i4250, i4650 and i4850 Scanners can provide a wide variety of electronic images. This can be done by using the TWAIN Datasource in concert with your scanning application. The TWAIN Datasource is the part of the capture system which links the scanner to your scanning application.

When using the TWAIN Datasource, the main Scanner window will display a list of Setting Shortcuts. Each Setting Shortcut is a group of specific image and device settings. The supplied Setting Shortcuts represent some common electronic image outputs used for a wide variety of input documents. If none of the Setting Shortcuts meet your scanning needs, you can create a customized Setting Shortcut. For example, you could create a Setting Shortcut called “Invoices” and whenever you want to scan invoices, you simply select that Setting Shortcut. For more information, refer to the sections entitled, “Creating a new Setting Shortcut” and “Changing image settings” later in this guide.

6	A-61839/TWAIN July 2016

How do I begin?

The goal is to make scanning as simple as possible. This is accomplished by selecting a Setting Shortcut from the main Scanner window and then selecting OK/Scan.

The scanner comes with some Setting Shortcuts already defined. In most cases, you will find that these shortcuts are all you will need. If you find that you need different settings, then you should create your own Setting Shortcut. Your shortcut will be added to the list of Setting Shortcuts and available for all future scanning.

Most of the options you will want to set are available on these two windows:

•Image Settings: clicking the Settings button on the main Scanner window, displays the Image Settings window. From this window you can set your image processing parameters by using the General, Size, Adjust, Enhance and Detect tabs. You can also access the Device settings, by clicking the Device button or the Advanced settings by clicking the Advanced Image Setup icon.

•Device Settings: the Device button is located on the Image Settings window. When you select Device, you will have access to the General, Transport, Multifeed and Patch tabs (if you have the Enhanced Printer Accessory installed, the Printer tab will also be available). From the Device Settings window, you can also access Diagnostics.

The procedures that follow describe how to configure a customized Setting Shortcut. Complete descriptions of the features and options on the Scanner window and tabs are found in the section entitled, “The main Scanner window”.

NOTE: Setting Shortcuts can sometimes be overridden by your scanning application. If this happens, the shortcut you access will appear in the main Scanner window in italics with the word <Changed> next to it. This is normal behavior for an application that does not use Setting Shortcuts and downloads its preferred individual settings to the scanner first and then provides access to the TWAIN Datasource.

When you click OK to begin scanning, you will be asked if you want to save the changed settings. When using an application that does not use Setting Shortcuts, select No to this prompt and continue scanning.
