ABSTRACT:
In a continuous form printer, a passage of the leading edge of the continuous form sheet is detected by a top sensor located along a feeding path thereof. A system determines whether the detection of the leading edge by the top sensor is correct, by comparing the feeding amount of the continuous form sheet after the feeding is started until the leading edge is detected with the distance between a feeding start position and the top sensor.
