Abstract: Color electrophotographic printers having latent image positions synchronized with start-of-scan signals. A laser source projects a laser beam onto a multifaceted rotating polygon that sweeps that beam in a scan line across a moving photoreceptor. A start-of-scan detector produces start-of-scan signals when the laser beam is in position to write a scan line. A belt sensor produces belt signals when indicia on the photoreceptor passes a reference position. A controller receives the belt signals and the start-of-scan and then adjusts the photoreceptors rotational velocity such that the belt signals are an integral multiple of the start-of-scan signals. To reduce the impact of drive roller eccentricities on belt signal to start-of-scan signal timing, the perimeters of photoreceptor roller elements are sub-multiples of the photoreceptor length.

Abstract: An image is accurately recorded by a light beam on a PS plate wound on a drum which is rotating at a constant speed. A rotary encoder detects information of a recording position in a main scanning direction by the light beam that is emitted from an optical unit to the PS plate. Based on the detected information, a PLL circuit of a recording synchronizing signal generating unit generates an original clock. Pulses of the original clock are counted by a decimating counter, which outputs a decimating instruction to decimate a pulse from the original clock each time the count reaches a preset count. Based on the decimating instruction, a pulse is decimated from the original clock, and a decimated clock is frequency-divided at a fixed frequency-dividing ratio by a frequency divider, which outputs a pixel clock for recording the image. Since the frequency of the pixel clock is varied by decimating the original clock based on the preset count, the image can accurately be recorded on the PS plate by determining in advance the preset count depending on the positional relationship between the PS plate and the optical unit.

Abstract: A method for correcting scanning errors in a shuttle type of a scanner, including the steps of scanning a pattern sheet on which pattern data having a specified shape are recorded. Errors for decline of the pattern data are corrected by using the pattern data having a straight line among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using the pattern data having the specified shape among the pattern data of which the errors for decline are corrected. Accordingly, since the errors for decline and the errors for distance between the bands can be corrected by using a computing program, there is an advantage in that correcting the errors of the pattern data is very simple. A further advantage is in that even if the scanner is subjected to an impact from its exterior, correcting the errors for decline and the errors for distance between the bands can be promptly performed.

Abstract: The recording apparatus includes a recording head that performs dot-recording on the recording material through a plurality of recording elements arranged on the recording head; a mechanism to move the recording head in a main scan direction to perform recording; and a transport mechanism to feed the recording material in a sub-scan direction perpendicular to the main scan direction after each main scan operation. The transport mechanism is formed of a combination of driving elements including a driving source. The feeding distance that the recording material is fed in one feeding operation is set synchronized with the driving cycle of the driving elements including the driving source. This arrangement allows the recording head, which has an array of ink ejection nozzles arranged with a conventional density, to produce a dot-recorded image having a resolution two or more times higher than the conventional resolution.
