3.4.2 Basic Sequence of Operations
The transport block uses a sequence of operations that consists of the following 5:
1. Horizontal Registration Detection [1]
Detects the position of the paper.
2. Horizontal Registration Correction [2]
Corrects the position of the paper with reference to the result of horizontal registration detection.
3. Alignment [3]
Switches the position of the stack with reference to the result of horizontal registration detection. (only in shift mode)
4. Buffer Operation [4]
Keeps the sheet stationary inside the transport block; thereafter, joins it with the subsequent sheet for forward movement.
5. Movement Switch-Over [5]
Moves the paper to the stacking block or the saddle stitcher block.
The particulars of individual operations are as follows:

3.4.3 Horizontal Registration Detection
1) About 150 msec after the lead edge of paper has moved past the inlet sensor (PS3), the finisher controller PCB causes the horizontal registration detection unit
shift motor (M6) to rotate clockwise so that the horizontal registration sensor (UN12) moves to its standby position (paper edge) from home position.
