<Skew Correction Control>
The Through Path Unit has the Front and Rear Alignment Plates that move to align the side edges of paper during feed.
1. At the start of a job, the Front Alignment Plate and the Rear Alignment Plate move to their respective positions 7 mm outside
from the paper width specified on the host machine (paper receiving positions).
2. When the trailing edge of paper is detected by the Through Path Inlet Sensor, the Front Alignment Plate and the Rear
Alignment Plate move inward, correcting paper screw during feed.
3. When the leading edge of the next sheet reaches the Through Path Inlet Sensor, the Front and Rear Alignment Plates move
back to their respective paper receiving positions.
4. Operations 2 and 3 are repeated until the job is completed.
