VRS Menu Commands The VRS menu consists of the following commands: Preview Use this command to open a sample image, so that you can test image property settings. For more information, see the section Previewing Images on page 37. Profile Use this command to select a profile, which consists of user-defined settings for image processing.
VRS Getting Started Guide Defining Exception Conditions Before scanning, set up parameters that define your requirements for image quality and exception handling. To set the parameters, open the VRS Administration Utility dialog box by selecting the Configure command from the VRS menu. The VRS Administration Utility dialog box consists of dual tabs relating to two exception types. The Warnings tab relates to image quality issues, and the Errors tab relates to equipment conflicts and paper transport issues.
VRS Getting Started Guide Selecting the Threshold The threshold defines the "margin of error" that VRS tolerates for brightness, contrast, missing corners and blank pages. VRS intercepts any image with values that fall outside the margin of error. VRS handles the image according to the action you define for each exception type. Brightness Out of Range Threshold Use the threshold to define the valid range for brightness values.
VRS Getting Started Guide Note: You may need to adjust the Blank Page threshold setting according to the color of the document. For example, a threshold that successfully detects a white blank page may not detect a dark green blank page. If you plan to scan colored documents, it is a good idea to scan a sample of each color to test the Blank Page threshold setting. Selecting an Action When a warning condition occurs, VRS handles it according to the Action setting you select.
VRS Getting Started Guide Table 2. Error Types Error Description Paper Jam Paper jam occurs in the scanner paper path. Out of Paper* No paper is available to scan.

Mode Menu By selecting the Mode command from the VRS menu, you can request that the VRS user interface display under the following conditions: Stop Every Page VRS dialogs open after each document scans; or with duplex scanning, after each document side scans.
VRS Getting Started Guide Updating Image Properties While scanning, you can use VRS to apply property changes to images that are intercepted as exceptions. To update an exception image, use the VRS Interactive Properties dialog box to apply property changes to the image shown in the VRS Viewer. The VRS Interactive Properties dialog box and the VRS Viewer open under the following circumstances: • When VRS intercepts an exception image for which the response is defined as Interactive.
VRS Getting Started Guide Using the VRS Viewer The VRS Viewer displays scanned images for your inspection. The purpose of the Viewer is to show you what an image looks like when it scans, and to refresh the image as you apply property changes. Note: To ensure that the VRS Viewer refreshes images as quickly as possible, you can enable the Accelerated VRS Refresh function from the Options tab. See the section Using the Options Tab on page 33.
VRS Getting Started Guide Using the VRS Interactive Properties Dialog Box The VRS Interactive Properties dialog box consists of seven tabs, including four with options for dynamically adjusting image properties as you scan. The tabs are shown in Figure 18. Figure 18. VRS Interactive Properties Dialog Box When the dialog box opens for an exception condition, the status line lists the specific cause for the warning or error. Otherwise, you see "Status OK" on the status line.
VRS Getting Started Guide Options Use this tab to activate optional features, such as Automatic Deskew, Image Crop, Accelerated Scanning, and VRS Refresh. For details, see the section Using the Options Tab on page 33. Analysis Use this tab to view a summary of the property settings for the most recently scanned image. For details, see the section Using the Analysis Tab on page 35.
VRS Getting Started Guide Using the Clarity Tab The Clarity tab provides options to adjust the contrast, brightness, and gamma correction for an image. Contrast relates to the range of the lightest and darkest shades in an image. Brightness relates to the intensity (or density) of the gray shades in an image. Gamma relates to the contrast between the light and dark areas of an image. Figure 19.
VRS Getting Started Guide Blue Rectangle This box shows you the region of acceptable Brightness and Contrast values. The box is centered around the baseline settings for Brightness and Contrast, with the borders representing the Brightness and Contrast threshold values from the VRS Administration Utility dialog box. Valid settings must fall within the blue box. Invalid settings fall outside the blue box borders, and they generate warnings.
VRS Getting Started Guide Using the Noise Tab The Noise tab gives you a set of filters that enhance image quality and remove excessive speckling. As you adjust the Noise settings, the effects are applied to the image in the VRS Viewer window. You can fine-tune the settings until the image appearance meets your quality standards. Note: The Noise tab settings are intended for black and white scanning; they have no effect on grayscale scanning. Figure 20.
VRS Getting Started Guide 4 Use the Speckle Removal Slider to remove unwanted black dots. a Move the slider toward Small if removal of small dots will achieve the desired image quality. b Move the slider toward Medium if removal of small and medium dots will achieve the desired image quality. c Move the slider toward Large if removal of small, medium, and large dots will achieve the desired image quality.
VRS Getting Started Guide Using the Skew Tab The Skew tab gives you settings to straighten an image that appears to be skewed, or crooked, in the VRS Viewer. To straighten an image, you rotate it up to 45 degrees clockwise, or counterclockwise. Use the movable angle control arm to rotate the image. If necessary, you can fine-tune the rotation with the Fine Angle Adjustment slider. The Angle box on the Skew tab lists the current image angle. When the Angle box lists 0.00, the image is not skewed.
VRS Getting Started Guide ! To change the Skew tab settings 1 From the VRS Interactive Properties dialog box, select the Skew tab. 2 Adjust the movable angle control arm until the image is straight: a Use the mouse to select the vertical arm. When selected, the pointer changes to a hand icon. b Move the arm counter-clockwise to rotate the image to the left, or clockwise to rotate it to the right. The Angle setting changes as the image rotates; the valid range is -45 degrees to 45 degrees.
VRS Getting Started Guide Using the Profiles Tab The Profiles tab helps you set up and manage VRS image property profiles. Each profile is a userdefined combination of settings for the Clarity, Noise, and Options tabs. You can establish multiple profiles to accommodate different scanning situations, so that you don’t have to repeat the process of defining image properties. VRS uses the profile Default settings, unless you define and select another one.

VRS Getting Started Guide Using the Options Tab The Options tab selections support automatic adjustments, accelerated scanning and image refresh, and assignment of optimal (or "intelligent") values for brightness and contrast. When you select a function from the Options tab, it remains in effect for the remainder of your VRS session, unless you change it again. Figure 23. Options Tab Automatic Deskew Activates the VRS feature that automatically straightens images that are skewed when they scan.
VRS Getting Started Guide Accelerated Scanning While high resolution settings have a positive impact on image quality, they can slow down the scanning process. With Accelerated Scanning in effect, VRS achieves the quality of a high resolution image without compromising speed. To maintain speed, VRS scans the image at a rate that is lower than the DPI (dots per inch) rate defined in your scanning application. Then, VRS performs an internal translation so that the image is output at the desired DPI setting.
VRS Getting Started Guide Using the Analysis Tab Use the Analysis tab to view a summary of the properties for the current image in the VRS Viewer. The summary reflects the properties at the time VRS scans the image. With the exception of the Speckle Count, none of the Analysis tab information is updated as you apply image property changes. You cannot edit the information on the Analysis tab. Figure 24.
