摘要： A pixel clock generation apparatus includes a detector detecting a time interval between two horizontal synchronization signals. A comparing part compares the time interval detected by the detector and a target value, and outputs the difference. A phase shift data generation part stores one or more lookup tables each storing a pattern of phase shift data for controlling a phase shift amount of a pixel clock, and reads and outputs the phase shift data from the lookup table based on the difference that is output from the comparing part. A high frequency clock generation part generates a high frequency clock. A pixel clock generation part generates the pixel clock whose phase is controlled in accordance with the phase shift data based on the high frequency clock.

摘要： A method and apparatus for detecting an abnormal paper feed such as a paper jam in a printing press which can reduce the work load for an operator and prevent productivity and printing quality from being lowered by detecting the elapsed time of travel of a first sheet of paper from a paper feeder to a register, with the time corresponding to the number of sheets reaching the register. This number is compared to a number of paper sheets stored in a memory. When there is an agreement between the compared sheet numbers, normal paper feeding is indicated. When the detected number of sheets is more or less than the number stored in memory, abnormal paper feeding is indicated and further paper feeding is interrupted. A number less than the required number is indicative of paper remaining on a feeder board from a previous printing operation. A number larger than the required number is indicative of a paper jam.
