摘要： A toner patch sensor for use in an image forming device may be operated in different modes according to the color of the patch being sensed. The toner patch sensor may include a detector and a source adapted to transmit light that is reflected off a toner patch and towards the detector. The detected light may be specular and/or diffuse. A controller may selectively change the amount of one or both of the specular and diffuse light received by the detector. The source may include separate emitters for the specular and diffuse light, with the controller selectably turning off one of the emitters or selectably adjusting a ratio of illumination power between the emitters. Alternatively, the source may include a single emitter and an optical element to split light between specular light and diffuse light. Diffuse light may be blocked when sensing black toner patches.

摘要： An apparatus for illuminating a photoconductive surface. The apparatus includes a housing defining a chamber and an open end. An imaging device is placed in the housing chamber. The imager transmits light rays through the open end of the housing to the photoconductive surface. An air pump is coupled to the housing. The air pump maintains an outwardly directed flow of air from the open end of the housing so as to move particles away from the open end. Electrically biased electrodes are located between the imaging device and the photoconductive surface. They attract the particles so as to prevent the particles from contaminating the imaging device.

摘要： An apparatus which detects a mass of marking material developed on a test patch recorded on a photoconductive surface. The apparatus includes a densitometer, a capacitor sensor and a controller. The densitometer is spaced from and adjacent to the photoconductive surface. The capacitor sensor is also positioned adjacent to the photoconductive surface and spaced therefrom. In operation, the densitometer generates a first signal proportional to the specular component of the total reflectivity of the material deposited on the test patch developed on the photoconductive surface. The capacitor sensor generates a second signal proportional to the mass of material developed on the test patch recorded on the surface. In response to these signals, the controller generates a first control signal as a function of the first signal received from the densitometer in response to the mass of material deposited on the test patch being less than a preselected mass. When the mass deposited on the test patch is greater than the preselected mass, the controller generates a second control signal as a function of the second signal received from the capacitor sensor. In this way, a continuous signal is transmitted from the controller independent of the color of the material developed on the test patch.

摘要： An apparatus for dispersing and/or transporting/migrating particles such as toner that may be prone to agglomeration in a particle dispensing system. Movement and/or vibration of the dispersing and migrating plate member serves to break up, clear and prevent particle agglomerations. Perforations, slits or mesh areas in the upper surface of the plate member can prevent oversize particles/agglomerations from passing through the system, while side walls, fins or disposing the plate member at a angle can channelize the dispersion of the particles contacting the upper surface of the plate member.

摘要： Artificial toner consumption is triggered to minimize the incidence of “conditioned” toner when a comparison of the rate of toner consumption to the mechanical activity of the electrophotographic printing device indicates that the toner consumption rate is too low. The artificial toner consumption operation may be achieved through a dummy print operation where an intentionally un-printed image is formed on a photoconductive drum, but the corresponding toner is routed to appropriate waste toner reservoir(s) and the image is not printed on the recording medium. The dummy print toner may be cleaned from the photoconductive drum without being transferred to an intermediate transfer medium and/or may be cleaned from the intermediate transfer medium, both without transferring the toner to the recording medium. The dummy print operation may correspond to a next normally occurring interdocument gap or a dedicated dummy print period inserted between print jobs.

摘要： A development system for developing a latent image so as to compensate for differences in the surface roughness of different types of copy papers receiving the developed image. The development system includes a development unit for each color of toner particles being used within the machine for latent image development. Each development unit has a first developer material supply source, and a second developer material supply source, containing respectively a first developer material and a second developer material of a same color. In order to more fully correct for hue and density differences in images of the same color developed and transferred onto rough versus smooth surface type copy papers, the first developer material importantly contains a higher level of pigmentation than the second developer material.
