摘要： An apparatus in which a plurality of developer rollers develop a latent image recorded on a flexible photoconductive member. The photoconductive belt is deflected by the developer material to wrap around at least a portion of the first two developer rollers forming wrapped development zones. The last developer roller may either have the photoconductive belt wrapped about a portion thereof, or the photoconductive belt may remain in an undeflected condition. The developer rollers having the photoconductive belt wrapped thereabout rotate in opposite directions. A blanket of developer material is formed between the last two developer rollers. An apparatus of this type optimizes development of the latent image recorded on the photoconductive member.

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： The white vector—the voltage difference between white areas of a latent image on a photoconductive unit and a developer roller—may be independently adjusted at each photoconductive unit, allowing multiple image forming units to be driven from a shared power supply. The photoconductive unit is charged to a high voltage level relative to the developer roller, and selectively optically discharged to the desired white vector by a first laser source. The voltage of the discharged area may be measured, or may be calculated by increasing the developer roller voltage a predetermined amount, discharging the photoconductive unit until toner is sensed in white image areas, and then reducing the developer roller voltage. The white areas are discharged using a different light source, such as a laser, LED or electroluminescent source. A second laser may be of a different wavelength than a writing laser.

摘要： A method and apparatus for compacting a liquid ink developed image on an image bearing surface in a multicolor electrostatographic printing machine of the type utilizing liquid developing material, particularly an image-on-image type liquid ink multicolor system. The image compacting apparatus includes a biased electrode situated proximate to the image on an image bearing surface, and a liquid applicator for depositing liquid insulating material in a conditioning gap defined by the electrode and the image bearing surface. A high electric potential is applied to the electrode for generating a large electric field in the gap to electrostatically compress toner particles into image areas on the image bearing surface. The liquid insulating material is deposited into the conditioning gap for avoiding the risk of air breakdown as may occur in an electrostatic device of this nature due to the small geometry of the apparatus and the tendency of air ionization in an air gap between electrically biased surfaces. Preferably, the liquid insulating material is the very same material utilized as the liquid carrier component of the liquid developing material.
