ABSTRACT:
Apparatus and control circuitry used in a copy machine for providing copy paper cut to length in accordance with an original sheet sensed by two switches in the path of travel of the original. A first feed roller is rotated via a clutch upon energization of a solenoid for the cluch when the leading edge of the original is sensed by the first switch with the clutch disengaged upon deenergization of the solenoid when the leading edge of the original reaches the second switch to provide limited movement of the leading edge of the copy paper from a solenoid operated cutter to a second feed roller. The second feed roller continues to pull copy paper from the roll until the cutter is operated by energization of its solenoid upon passage of the trailing edge of the original past the first switch. The cutter solenoid is deenergized when the trailing edge passes the second switch.
