Abstract
The present invention provides a method and system for optimizing the time required for scanning a document with any conventional scanner. More specifically, the present invention will utilize calibration information from the initial power-up calibration or any other calibration, and the information from any previous scans to expedite or eliminate the need for future calibration requests. This process will save time for the user to obtain an optimal scan and increase the operable life span of the scanner by eliminating many repetitive scan cycles.
