Exceptions
Use the Exceptions panel on the Administration Console to manage how VRS responds to warnings and errors that may occur under specific image or scanner exception conditions.
Warning
The Warning list consists of exceptions associated with image quality. For each warning, select a threshold and an action. The threshold setting defines a "margin of error" that determines whether or not VRS issues a warning. The action setting determines how VRS responds to a warning. See the Action list below.
Threshold
The threshold defines the "margin of error" that VRS tolerates before issuing a warning for an exception image.
Examples:
Error
The Error list consists of exception conditions related to Auto Crop, Auto Deskew, equipment conflict, paper transport, and other issues. The action setting determines how VRS responds to an error. See the Action list below.
Action
Use the Action box to specify how you want VRS to respond when each warning or error occurs. The table describes the actions that you can set.
|
Action |
Description |
|---|---|
|
Ignore Error |
Does not notify you of the error or take any action to correct it. VRS accepts the image "as is," passes it to the scan application, and continues the scan operation. |
|
Return Error |
Notifies you of the error but does not send the image to the scan application. The scan operation is stopped. |
|
Intervention |
Opens the Kofax VRS Auto Resolve Manager in manual mode, so you can manually resolve an equipment or paper transport error such as a loose cable, paper jam, or out of paper condition. To resume processing, you must manually restart the scan operation. |
|
Auto Resolve |
Opens the Kofax VRS Auto Resolve Manager in automatic mode. The scanner automatically resumes processing as soon as you resolve an equipment or paper transport error such as a loose cable, paper jam, or out of paper condition. |
|
Interactive |
Pauses the scan operation to display the exception image in the Kofax VRS Interactive Viewer, so that you can apply quality adjustments. |
Accelerated Scanning
For a limited number of scanners, throughput is reduced when the scan application is set for bitonal scanning. If a slowdown occurs while you are scanning bitonal images, you can use the Accelerated Scanning slider to improve the throughput so the scanner runs at (or near) the rated bitonal speed.
For some production class scanners, a reduction in throughput may occur with any color mode. With these scanners, you can use the Accelerated Scanning feature to improve the throughput, regardless of the color mode setting. Be aware that the Accelerated Scanning setting may have no effect on some scanners.
Use the slider to select a scanning acceleration level from None to Maximum. As you move the slider closer to the Maximum setting, the potential for image quality degradation is increased.
Background
When a scan application is set for bitonal processing, VRS actually requests an interim grayscale image to produce a clean, clear, bitonal image. For a limited number of scanners, a slowdown may occur while the image is processed.
If you prefer your scanner to run at, or near, rated bitonal speed for bitonal processing, use the Accelerated Scanning slider to accelerate the scanner and experience only a slight reduction in image quality. VRS performs the acceleration by scanning at a resolution lower than the one requested by the scan application. VRS then scales the image up to the resolution requested by the application.
The acceleration process may affect image quality. As you move the slider from no acceleration to Maximum, the difference between the requested resolution and the actual scanned resolution is increased. At the maximum acceleration level, the difference is the greatest and so is the potential impact on image quality.
For example, suppose you select 300 dpi in your scan application and set the first level of accelerated scanning in VRS. The image scans at 200 dpi to accelerate the scanning speed and VRS translates it to 300 dpi to achieve the desired resolution.
At the lowest level of accelerated scanning, the image quality is virtually equivalent to non-accelerated scanning. However, higher levels of acceleration affect the image quality. Not all scanners increase in speed when you select accelerated scanning. If your scanner does not offer resolutions lower than the one selected in your scan application, accelerated scanning will have no effect.
