    Abstract: An engraving system (10) and method is disclosed having multiple engraving heads (22, 24) wherein the operation of each head is controllable so that a vertical and/or horizontal screen may be independently controlled, enabling each engraving head to engrave in accordance with different screen rulings selected by a user. The engraving system includes a signal generator for controlling the vertical screen by utilizing a plurality of vertical scalers which use a cylinder factor signal corresponding to the rotational position of a cylinder (16) and as screen variables, such as a screen angle and screen ruling, to generate independent vertically scaled signals which are used to independently energize the engraving heads to engrave patterns defining different vertical resolutions or vertical screens. This system and method also discloses a drive system (28) for independently driving the engraving heads using the cylinder factor signal and the screen variables to enable the engraving heads to engrave patterns having differing horizontal resolution or horizontal screens.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner which suppresses tilting of a scan line even if the ratio of the linear speed of a latent image carrier and the speed of the scanning line is varied, and also to provide an image forming apparatus. SOLUTION: The tilting of the scanning line on a surface of a photoreceptor drum being a latent image carrier is adjusted according to the ratio K of the scanning speed Vimg of a light beam scanning the surface of the photoreceptor drum and the linear speed (process linear speed) V of the photoreceptor drum. The tilting of the scanning line is thereby suppressed when the ratio K of the process linear speed V and scanning speed Vimg is different. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: An image forming apparatus includes a drum, an optical scanning mechanism, a development mechanism, an intermediate transfer member, movement detecting mechanisms, and a controller. The optical scanning mechanism deflects a laser light beam to form a latent image on a photosensitive surface of the drum. The development mechanism contains a plurality of different color toners and develops the latent image into a color toner image. The intermediate transfer member is rotated in synchronism with a rotation of the drum and receives the color toner image multiple times to form thereon a composite color toner image including multiple images of the different color toners overlaying one to another. The movement detecting mechanisms detect respective movements of the drum and the intermediate transfer belt. The controller controls respective rotations of the drum and the intermediate transfer belt with results of respective detection performed by the plurality of movement detecting mechanisms.
