The booklet transport motor also drives the positioning roller [A] to vertically align
paper against the positioning plate [B].
The positioning roller is not round but elliptical in shape so that it moves away from
the paper while the paper is being horizontally aligned.
The positioning roller sensor [C] detects the actuator [D] on the roller shaft to
determine the rotation of the positioning roller. When the sensor is de-actuated, the
roller is away from the paper and the jogger fences [E] start moving.
