Abstract: In accordance with the present invention, a method and a system for increasing scanning speed are provided. The method comprises steps of determining a transmission rate of a transit interface, scanning an original to generate an image data, and adjusting a cycle time of the image data to change a data generated rate responsive to the transmission rate of the transit interface. The key aspect of the present invention is by adjusting the cycle time of a state machine to change the data generated rate corresponding to the transmission rate of the transit interface. Therefore, in response to the transmission rate of the transit interface, the cycle time of the state machine is adjusted to produce the data at a rate that prevents the smearing process. Thus, incorporated with the present invention, the possibility of memory buffer full is reduced leading to the reduction in the time wasting on start-stop processes and therefore the overall scanning speed is increased without requiring the increase in size of a memory buffer.

Abstract: A skew correction apparatus for cut-sheet paper feeding used in office machines such as optical scanners, printers and copiers. It includes a C-shaped paper guide surrounding a drive roller to form a paper passage therebetween. At one end of the paper guide, there is a concave groove and a slanted slot which holds an elastic plastic flap therein. The flap is spaced from a pinch roller which makes contact with the drive roller for feeding a sheet of paper from the paper passage to a working station for performing a desired work such as scanning, printing, and copying. The flap has a depending tongue to stop a skewed leading edge of a sheet of paper. The paper buckles behind the skewed leading edge caused by the rotating drive roller and is held in the concave groove until the trailing edge of the skewed paper reaches the flap. The leading edge thus is aligned properly without skew and pushes and deflects the tongue and moves to the pinch roller and the drive roller which move the paper to the working station.
