  • Patent number: 6882819
    Abstract: An image forming apparatus, having imaging units arranged alternately on both sides of a continuous paper web, is characterized by minimized image misregistration and reduced processing cost. In order to prevent possible color misregistration caused by changes in paper feed path length resulting from the eccentricity of each drive roller, the difference in the eccentric phases of the rollers on the front and back surfaces is controlled, thereby minimizing the difference in changes in paper feed path length.

  • Patent number: 6741830
    Abstract: When initially routing a continuous web along a path, the web walks across the width of the path, and uneven tension occurs causing the web to break in some cases when printing tension is applied thereto. Further, uneven web tension is produced on the right and left of the web by excessive walk control resulting from an excessive deviation of the web from the target position of a walk controller, with the result that the web is crumpled and broken. These problems are solved by maintaining a web tension that is lower than the printing tension until the web position converges on the target position of the walk controller after loading of the web, thereby reducing the amount of correction by the walk controller and the amount of web lost in the preparatory phase before printing, with the result that excellent image quality free from crumple or breakdown is ensured.

  • Publication number: 20030215273
    Abstract: An image forming apparatus characterized by the minimum image deterioration. The surface of a feed roller immediately after a fixing unit is covered with a mold release member to improve the mold release property of molten toner, and cooling means for forcible cooling of a web and a feed roller to improve the coagulation of molten toner, whereby high temperature offset is avoided. Further, a heat insulating member is arranged inside the mold release member of the feed roller, thereby increasing the thermal time constant, ensuring a quick cooling cycle and reducing the thermal expansion of the feed roller.

  • Publication number: 20030053833
    Abstract: According to the conventional technique, a web walks across the width in paper routing, and uneven tension occurs to break the web in some cases when printing tension is applied. Further, uneven web tension is produced on the right and left by excessive functioning of walk control resulting from an excessive difference from the target position of a walk controller, with the result that the web is crumpled and broken. These problems are solved by the present invention wherein web tension is kept lower than printing tension until the web position across the width converges on the target position of a walk controller after loading of the web, thereby reducing the amount of correction by the walk controller and the amount of web lost in the preparatory phase before printing, with the result that excellent image quality free from crumple or breakdown is ensured.

    Abstract: An image production apparatus includes at least one image production unit having a latent image forming device for forming a latent image on an image carrying member and a developing device for attaching toner to the latent image formed by the latent image forming device. A toner image formed by the image production unit is transferred to a transfer medium to produce an image. The image production apparatus further includes a periodicity giving device for giving periodicity to movement in a main scanning direction of the image carrying member or transfer medium. According to this periodicity, the movement time from an image forming position to a transfer position, or the movement time of a transfer medium between adjacent transfer positions is set equal to an integral multiple of the period.
