Abstract: There is provided an image forming apparatus that is capable of securing required printing quality by properly correcting a main scanning scale. In a pixel division modulating process, for each of one or more correction points (at l-th, m-th, and n-th pixels) on each of lines along which scanning is carried out on a photosensitive drum 11 by laser light, the final bit data of pixel-division-modulated pixel data of a pixel immediately preceding each correction point is added to the pixel data of a pixel located at the correction point as the leading bit data of the pixel-division-modulated pixel data of this pixel. The same processing as above is sequentially performed on pixel data of pixels located subsequently to the correction point to sequentially shift predetermined bit data of pixel data of pixels to pixel data of the respective following pixels, to thereby generate pixel data of a new pixel. The generated pixel data of the new pixel is outputted in synchronism with an image clock of a fixed frequency.

Abstract: A method for calibrating a VCO within a phase locked loop circuit is disclosed. First, a DAC output voltage is set to its minimum, and a counter M is adjusted until a comparator is its threshold voltage. Next, the DAC is set to another voltage, and counter M is again adjusted to the comparator threshold. This process is repeated for as many steps as desired. When the phase locked loop circuit requests an instantaneous frequency, an interpolation of the requested frequency against the curve created by the above-described method gives the value required by the DAC.

Abstract: An image registration system for determining a relative location of a first pattern and a second pattern includes a fiducial having a fiducial origin, a first side, and a second side. A first camera captures a first fiducial image of the first side of the fiducial and the fiducial origin and a first pattern image of the first printed pattern. A second camera captures a second fiducial image of the second side of the fiducial and a second pattern image of the second printed pattern. An image registration controller processes the first fiducial image, the first pattern image, the second pattern image, and the second fiducial image to determine the relative location of the first pattern and the second pattern.

Abstract: An apparatus to control color registration and image density and a method of calculating a color registration error. The apparatus includes registration marks formed on a transfer belt such that each of the registration marks includes a scan direction component and a slanting direction component at an angle with respect to both the scan direction and the cross-scan direction. The apparatus further includes image density marks formed on the transfer belt, having predetermined image densities, and a registration and image density sensor provided above the registration marks and the image density marks to radiate beams onto the registration marks and the image density marks. The sensor receives beams reflected from the registration marks and the image density marks to produce detection signals, and obtains registration information and image density information from the detection signals. Accordingly, X-offset, Y-offset, printing width error, and skew can be simultaneously compensated for using a single apparatus.

Abstract: To make it possible to improve a printing speed. When printing a plurality of printing sheets 14, it is possible to decrease the time for generating correction data by using a pair of correction data values to print the printing sheets 14. Therefore, it is possible to decrease the time for printing each printing sheet 14 even compared to the case of a method for generating correction data for each printing sheet 14. As a result, even when the number of sheets to be printed is large, it is possible to improve a printing speed. Moreover, when meandering states of the printing sheet 14 are changed, it is possible to prevent disorder of a printed image due to meandering of the printing sheet 14 for a long time by newly generating correction data. Furthermore, by generating (updating) only a part of correction data when newly generating the correction data, it is possible to decrease the time for generating the correction data and improve a printing speed.
