Abstract
A system that ensures that documents are perfectly aligned before scanner paper feed is enabled. Subsequently, the paper drive is activated and the resulting scanned image does not have any annoying skew. This system is particularly effective with fast start scanners having a scanning speed over 200 mm per second. Sheet-fed scanners can take advantage of this Anti-Skew Auto-start system at a marginal cost. The method and the special tools to calibrate the Anti-Skew Auto-start system ensure repeatable performance.
