Abstract: A data generating apparatus and a data generating method generate imposition data for imposing a plurality of pages on a print medium. A recording medium stores therein a program which enables a computer to function as an apparatus for generating such imposition data. After imposition data have been converted from grid data into fold data, trials are performed to fold a hypothetical print medium based on the converted fold data, so that pages, which are superimposed by folding the hypothetical print medium, have sequential page numbers and are oriented in one direction. Results of the trials are acquired as fold information for folding an actual print medium.

Abstract: A system for determining the return of the photo sensor in the scanner and the method thereof are disclosed. There are two base position sensing units in the system. Each of the base position sensing units computes the currents in two sections of a line resistance material defined by the position of the photo sensor after a document is scanned to determine which base position sensing unit the photo sensor should return to. This method reduces the return time of the photo sensor than the prior art in which the photo sensor can only return to a single end. Therefore, the system helps achieving the goals of increasing the scanning efficiency and saving power. Moreover, the system realizes the image scanning in both directions.

Abstract: In accordance with the present invention, a method and a system for promoting scanning speed are provided. The method comprises steps of determining a transmission rate of a transit interface, adjusting system clock responsive to the transmission rate of the transit interface to change a data generated rate, and scanning an original to generate data at the rate controlled by the system clock. The key aspect of the present invention is by adjusting system clock 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 system clock is adjusted to produce the data at a rate that can reduce the possibility of memory buffer full leading to the reduction in the time wasting on start-stop processes and therefore promote the scanning speed without requiring the increase in size of a memory buffer.
