Document Quality
Document quality is the primary factor in obtaining good copies from scanned originals. For most documents, the four Background Suppression key selections with DYNAMIC BACKGROUND REMOVAL enabled, which is the default setting, provides an accurate copy. Some documents, however, require manual adjustments to the settings.
This section explains the DYNAMIC BACKGROUND REMOVAL 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 Background Removal
NOTE: DYNAMIC BACKGROUND Removal cannot be disabled (unchecked) when using the Productivity mode.
The DYNAMIC BACKGROUND REMOVAL eliminates the need to make additional manual adjustments for most input documents. Select the Menu key > CONFIGURATION > IMAGE ENHANCEMENT.
This feature allows the system to dynamically adjust itself for each document. There are two modes associated with this feature:
•When DYNAMIC BACKGROUND REMOVAL 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 BACKGROUND REMOVAL 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 scan. It uses this fixed area to set the copy parameters for the remainder of the image being scanned. This operating mode should be used for documents with consistent background throughout.
