Q5686A/Q5687A STACKER II UNIT EXPLANATION 3.2 Operation 3.2.1 Alignment U control In the staple, folding, stitch-and-fold, and three-folding modes, the alignment along the width of paper con- veyed to the stacker is made by rotating the alignment motor U (M705) in normal or reverse direction to open or close the alignment plate U. The alignment HP sensor U (PS708) detects the home position of the alignment plate U. An finisher operation signal from the finisher starts to rotate the alignment motor U (M705) in the direction A. Alignment /U control in which the alignment plate U closes and stops at the stand-by position in which the alignment plate is open a little wider then the paper width.
A specified period of time after the stacker entrance sensor (PS705) detects the trailing edge of paper, M705 rotates in the normal or reverse direction to oscillate the alignment plate U for proper alignment of paper. Alignment is made each time a sheet of paper is sent in.
