Booklet maker compiler section paper feed and alignment
When the sensor (SHPF booklet gate) detects the leading edge of the paper, the motor (booklet maker tamper) moves
the tampers to a width that is slightly wider than the paper. The motor (booklet maker aligner) moves the aligner to a
preset position depending on the paper length.
The motor (booklet maker paddle) rotates the upper and lower paddles. The paddles push down the paper to align the
short edge on the aligner. After the trailing edge of the paper passes the sensor (booklet maker transport), the tampers
move back and forth to align the long edge of the paper.
The paddles stop rotating after the trailing edge of the paper passes the sensor (SHPF booklet gate). The tampers return
to the home position after the alignment is completed. Succeeding sheets are individually fed and are aligned in the
same manner.
After all of the sheets are aligned, the aligner solenoid retracts the stack clamp to hold the paper stack in place for
folding. The aligner moves to a preset position depending on the number of folds needed.
