Document quality
Document quality is the primary factor in obtaining good copies from scanned originals. For most documents, the Dynamic IQ feature of the Synergix Digital Solution provides an accurate copy. Some documents, however, require manual adjustments to the settings to achieve the best copy quality.
This section explains the Dynamic IQ feature, describes the characteristics of good quality and bad quality documents, provides tips for preparing and organizing documents for scanning, and summarizes the procedures for scanning documents of different quality types.
Dynamic IQ
The Dynamic IQfeature of the Synergix Digital Solution eliminates the need to make additional manual adjustments for most input documents. Refer to Menu, Configuration, Scanner Control to enable/disable this feature
Dynamic adjustment of copy quality
This feature allows the system to dynamically adjust itself for each document. There are two modes associated with this feature:.
•When Dynamic IQ is enabled, the image is continually monitored as it is being scanned and the copy quality parameters adjusted to achieve the best copy quality.
•When Dynamic IQ is not enabled, the process takes a 0.70 inch (17.8 mm) snapshot over the full width of the image after the first 1.5 inches scanned. It uses this fixed area to set the copy parameters for the remainder of the image being scanned
Dynamic Background Suppression only monitors the document in the process direction, from the lead edge to the trail edge. It cannot make adjustment from the left side to the right side of the document. For example, if the input document is dark, Dynamic IQwill automatically make the
appropriate compensation to optimize the reproduction of the dark details. If the input document has a faded background, the Dynamic IQfeature will enable a faithful reproduction of the original. However, the faded background must be inserted with the fading running in the process direction with the darker side being inserted first.
In some cases, you may wish to optimize the settings for individual documents. For example, you may not wish to faithfully reproduce
The Dynamic IQfeature, when enabled, uses information about the document captured during the scanning process to set image quality settings. The system automatically adjusts for the darkness of the background and the image content through out the length of the document. When not enable, it only uses the information in a 0.70 (17.8 mm) area over the width of the document to establish the image quality settings. Therefore, best results can be obtained if the document is fed in with an edge that has a representative sampling of both the background and the foreground image.
The Dynamic IQ™ feature provides an accurate copy for most documents including blueline, blueprints, color line art/text, and mixed documents containing combinations of halftone and art, or photograph and art. For documents with inverted images, the INVERT function should be enabled. Refer to "Inverting an image" in the "Special features keys" section for instructions on the INVERT function.
