Abstract: A hybrid jumping development system utilizing two component developer and providing an improved device for controlling developed toner mass. Toner is metered onto a donor structure and a toner cloud is formed in a development nip between the donor structure and the charge retentive surface having a latent electrostatic image thereon. The toner cloud is formed by applying an alternating potential to the donor structure so as to cause the toner particles to jump off of the donor structure. The duty cycle of the AC potential is used to control the toner cloud and thus the amount of toner developed on the charge retentive surface.

Abstract: A method of joining substrates at their lateral edges uses an elongated stiffening member to provide the requisite rigidity and strength for the application in which the joined substrate is to be used. The joining method is useful in any type of application that shares three functional requirements: The joined substrate sections must produce a unitary substrate construction with sufficient rigidity and strength to maintain the substrate sections in a joined position during a subsequent processing operation on the unitary substrate and thereafter when a completed assembly composed of joined substrates is installed as a component of another apparatus. Secondly, if components are formed on a substrate prior to joining, the integrity of those components must remain intact and uncontaminated during the joining process in a manner that would permit a subsequent operation to successfully use the components.

Abstract: Three fuser rollers cooperate with a pressure roller to form an extended fusing zone through which a substrate carrying toner images passes with the toner images contacting a fusing belt. Electrical power is applied to the three fuser rolls in such a manner that the portions of the belt in a fusing zone are heated to a predetermined operating temperature in accordance with a setpoint temperature. The free extent of the belt or in other words the portion of the belt outside of the fusing zone is adapted to be heated to various operating temperatures in order to produce prints with different gloss as desired.

Abstract: Reload characteristics of a development member such as a donor roll are monitored by using a machine exposure system (ROS or LED Bar) to generate a test image composed of a short (in the process direction) high density solid area patch followed by a long mid and lower density areas (solid or halftone), the later corresponding to Reload Defect (RD) exhibited by the development member. Typical dimensions of the test image would be a 15 mm square high density patch followed by a 200.times.15 mm mid and lower density regions. This test image voltage profile is placed in a skipped image frame inserted into a long job, or is effected during cycle-out/down following a shorter job run, and is scheduled at infrequent periodic intervals, for example, every 2000 prints. The resultant developed toner pattern on the photoreceptor is monitored, for example, with a reflectance or transmission density sensor such as the Toner Area Coverage (TAC) sensor used in the 4700.TM., 4850.TM., and 5775.TM.

Abstract: A main ink chamber with a through-hole contains a capillary member. An intermediate ink chamber is provided on the side wall of the main ink chamber. A path communicatively interconnects the main ink chamber and the intermediate ink chamber. A second meniscus forming member is disposed in a joint port, to thereby prevent ink leakage. In a print mode, ink flows from the main ink chamber to the joint port, through a meniscus forming member that is disposed in the through-hole. Air bubbles mingled into the ink move along the slanting upper wall of the path by their buoyant force, and are accumulatively stored in the upper part of the intermediate ink chamber. When ink is reduced to zero in the main ink chamber, air bubbles are introduced into the intermediate ink chamber through the meniscus forming member. As a result, the liquid level of the intermediate ink chamber is quickly reduced, thereby indicating a state that ink is used up.
