  • Patent number: 7944594
    Abstract: An image forming device that carries out color reproduction using plural of color materials having: a setting unit setting a color material curbing mode that curbs an amount of color material; and a color information inputting unit that inputs input color information. The image forming device further has a converting unit that, when the color material curbing mode is set by the setting unit, converts the input color information inputted by the color information inputting unit into output color information in a color material curbing region, on the basis of correspondence relationships that are set in advance such that a region that is color-reproducible by the image forming device is kept within the color material curbing region that is narrowed such that an amount of the color material is curbed.

  • Patent number: 7945182
    Abstract: Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. An influence of a pre-clean corotron on the charge receptor is modified, during the designated rotations of the charge receptor, while the portion of the surface on which the lubrication stripe is formed, or will be formed, is passing the pre-clean corotron. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade.

  • Patent number: 7942517
    Abstract: A method is implemented by a printer to move a transfix roller selectively to clean the transfix roller. The transfix roller is moved from a transfix nip with the print drum to a position where the transfix roller remains in rolling contact with the print drum, but exerts a pressure on the print drum that is less than the transfix pressure. The transfix roller is later moved out of rolling contact with the print drum in response to the transfix roller rotating a predetermined distance.
