2.2.1.2 Scanner Carriage Unit Movement Overview
Scanning image is performed in the main scan direction (=1 line) by the CIS board and
in the sub-scan direction (=several lines) combined with Scanner Carriage Unit
movement. (refer to the figure below) The CIS board can scan 1 line in main scan
direction (parallel to the Scanner Carriage Unit) by one time. When scanning next lines
after the second line in sub-scan direction, CR driving moves the Scanner Carriage
Unit, and scan the other lines. The scanned data is sent to the control board. The
scanned data for “n” lines and “n-1” line are processed consecutively.
