Presence check for paper

WT4-3, WT9-3 or WT12-3 fast miniature and small photoelectric sensors use a precise light spot to detect the positions of the paper front and back edges, regardless of the color of the paper. This determines the length of the paper sheet precisely and eliminates any background disturbances.
