摘要： An image formation apparatus with a plurality of laser diodes that form color-component images, which correspond to a plurality of color components, onto a plurality of corresponding photosensitive drums respectively, and a transfer belt onto which the color-component images that are formed on the respective photosensitive drums are transferred. The image formation apparatus adjusts the image formation timing based on the positions of the color-component images that are transferred to the transfer belt; and when adjusting the image formation timing, the respective laser diodes form color-component images at formation intervals that correspond to an integral multiple of the period of a periodic noise.

摘要： Methods and apparatus include aligning printing of a bi-directionally scanning electrophotographic (EP) device, such as a laser printer or copy machine. At least first and second scan lines formed in opposite directions define a calibration page for manufacturing, servicing or end-user operation. The page includes pluralities of objects with one formed from either the first or second scan lines, but not both, and another of the objects formed from the other of the first or second scan lines, but not both. In this manner, corrections can be implemented by simply observing misalignments between the objects. Printed calibration pages also include visually or mechanically read objects for implementing corrections. In this regard, calibrating devices external to the EP device are contemplated. Objects include lines, squares or other shapes and their arrangement on a page varies. Fiducials for macro-scale observations are also contemplated.

摘要： An image-drawing device, which carries out image-drawing on the basis of image-drawing data, has image-drawing heads which are moved relatively in a predetermined scanning direction along an image-drawing surface. The image-drawing heads have a large number of image-drawing elements lined-up two-dimensionally within a plane which is parallel to the image-drawing surface. The straight lines along which the plural image-drawing elements are lined-up are inclined, with respect to the scanning direction, at a predetermined inclination angle such that an image-drawing magnification has an effective value after a decimal point. A data allocating unit allocates the image-drawing data to the respective image-drawing elements at predetermined timings corresponding to a resolution determined in accordance with the image-drawing magnification. In this way, resolution in the scanning direction can be increased without making a scanning speed of the image-drawing heads slower or making a modulation speed of the image-drawing elements faster.
