Abstract
The present invention features a check-reading and check-validation machine having a programmed microprocessor, a photo-sensor, a magnetizing unit, a magnetic head reader, feed rollers and a stepper motor drive for rotatively driving the feed rollers. The machine may be a sub-unit of a printer. A check is introduced to the nip of the feed rollers. The photo-sensor detects the presence of the check and activates the stepper motor drive. The stepper motor drive then causes the feed rollers to rotate, drawing the check into the reading and validating machine. The microprocessor instructs the stepper motor to feed and discharge the check into and out of the machine, according to a specialized program. The microprocessor program initially instructs the stepper motor to rotate the feed rollers for forward drive, utilizing half-step pulsing. As the check moves past the magnetizing unit and the magnetic head reader, on forward motion into the reading and validating machine, magnetic characters on the check are magnetized. After the calculated number of pulses required for the check to pass the magnetizing unit and the magnetic head reader, the program instructs a reverse-drive direction fo…
