Abstract: An image forming apparatus has a normal image formation mode and a wide color gamut image formation mode in which an amount of a developer per unit area of a developer image of at least a color that differs from a prescribed color among a plurality of colors is increased as compared to the normal image formation mode. Image data is generated such that an image portion formed in the prescribed color in an image formed on a recording material is formed solely by a developer image of the prescribed color in the normal image formation mode, but formed by superimposing a developer image of a color that differs from the prescribed color on a developer image of the prescribed color or formed solely by a developer image of a different color in place of a developer image of the prescribed color in the wide color gamut image formation mode.

Abstract: An electrophotographic printing system for printing with a set of toners including a white toner. A plurality of printing modules are configured to print respective toner patterns, each including a toner image printed onto a receiver medium being transported on a transparent transport web and a corresponding registration mark positioned outside a border of the receiver medium. A registration mark sensing system is positioned to detect the printed registration marks. The registration mark sensing system includes a light detector positioned to detect light that is emitted by a light source, transmitted through the transport web and reflected off a non-white colored reflector plate positioned behind the transport web. The colored reflector plate has a color that provides detection signals for the registration marks having a magnitude that is greater than or equal to a predefined threshold.

Abstract: Methods and apparatuses that facilitate the alignment of multiple color planes of a latent image in a multi-beam multi-pass printer. The methods include determining, during a first pass of a transfer medium of a multi-beam printer, a first time interval between when at least one light beam from a multi-beam device is detected and when a top of a page is detected at a selected location of the transfer medium, the multi-beam device including a plurality of light beam sources, and the first pass to form a first color plane of a latent image on the transfer medium. The methods further include selecting, based at least in part on the determined first time interval, a first one of the plurality of light beam sources to begin illuminating the transfer medium to create the first color plane on the transfer medium during the first pass of the transfer medium.

Abstract: A developing device is usable with an electrophotographic image forming apparatus including a shaft and a rotary unit mounting the device. When mounted, the device is movable perpendicular to a shaft axial direction in response to movement of the rotary unit and the shaft is not movable in that direction. The device includes a developing roller that contacts and separates from a drum in response to movement of the rotary unit, and a coupler transmitting a rotating force to the roller. The coupler includes a portion engaging the shaft to receive a rotating force and a portion transmitting the received rotating force to the roller. The coupler takes a first position for transmitting the rotational force to the roller, a position before the coupler engages the shaft and is inclined away from the first position, and a position for the disengagement of the coupler and the shaft.
