ABSTRACT:
In a continuous form printer, a passage of the leading edge of the sheet is detected by a top sensor located along a feeding path thereof. If the top sensor detects the leading edge of the sheet while the sheet is fed in a reverse direction, the control unit of the printer determines whether the detection of the leading edge by the top sensor is correct or not, by feeding the sheet once in the forward direction and then feeding the sheet in the reverse direction and by checking whether the top sensor again detects the leading edge of the sheet being fed in the reverse direction.
