Lens Position
There are three standard original positions for the platen, DJF and RDH
modes.
In platen mode, the original is aligned with both the rear [A] and the left [B]
original scales (rear left corner [C] is the standard position).
In RDH mode, the original position is the center of the left scale [B].
In DJF mode, the original position is 5 mm to front of the platen mode original
position to maintain the original transport path (5 mm from the rear scale).
The above figure shows the lens horizontal positions for each original mode
when identical size paper is used.

To keep high paper feed performance, the center is assigned as the paper
feed standard position. Therefore, the lens horizontal position is changed
according to the paper size.
The figure shows the lens horizontal position for each paper size in full size
mode.
