Abstract
An image correction device includes an input tray, a pickup roller, a separation roller, a plurality of first and second feed rollers, a scanning area, a sensor unit, a control unit, a plurality of paper-out rollers and a paper-out tray. The control unit electrically connects with the sensor unit and controls rotating speeds of the first and second feed rollers. An image correction method of image correction device is described hereinafter. When the paper is going to pass through the scanning area, the sensor unit sends a first signal to the control unit, when the sensor unit detects a transmitting status or a transmitting speed of the paper to be changed, the sensor unit sends a second signal to the control unit for modulating rotating speeds of the first and second feed rollers and the transmitting speed of the paper until the paper is scanned completely.
