(3) Y (Crosswise) Direction Lens Motion Mechanism/Control
The Lens must be moved in the Y-direction, since the original is always
aligned with the rear side for registration regardless of the paper size
(crosswise length) and zoom ratio.
•
The Lens is moved in the Y (crosswise) direction by a rack and pinion gear
driven by Lens Y Direction Drive Motor M13. (M13 is a stepping motor and
turned forward or backward by the pulse signal output from Scanner
Control Processor Board PWB-J.)
•
When a zoom ratio is selected, the Lens is moved as follows. The M13’s
shaft turns 1.8° per step, which is equivalent to approx. 0.11 mm of linear
Lens movement.
*
The paper size widths range from the minimum 100 mm to 297 mm (A3).
*
Zoom ratios range from 0.5 to 2.0.
