Abstract: An system and related method for maintaining print quality based on development potential measurements that include comparing the current process measurements to a toner concentration related set-point; calculating a quality adjustment range based on current process measurements and the toner concentration related set-point, or a derivative thereof, indicative of print quality; and adjusting current process conditions related to the current process measurements to trend towards a new set point within the quality adjustment range so that a rate of change is proportional to the difference between the current process measurements and the set point.

Abstract: Controlling the charge on toner in a development station of an electrographic reproduction apparatus, wherein data relative to latent image charge carrying member voltage and image density control patches are sensed and development potential to achieve an aim density is calculated therefrom. A delta from an optimum development potential range is calculated, and in response to the determined delta, an amount of liquid charge control agent, from a supply of suitable liquid charge control agent, necessary to be added to the developer material in the development station to bring the toner to substantially a charge level that will enable a desired optimum developer potential is calculated. The calculated amount of liquid charge control agent is then injected directly into the development station.

Abstract: A package (30) for an individual charging wire (10) includes a backing (32) having a back portion (42) and a front portion (44). A first perforation (46) is defined in the backing (32) between the back portion (42) and the front portion (44). A closing strip (36) is disposed on the back portion (42). A padding strip (34) is disposed on the back portion (42) between the closing strip (36) and the first perforation (46). A second perforation (48) is defined in the back portion (42) between the closing strip (36) and the padding strip (34).

Abstract: A system, method, and apparatus for adjusting dry ink concentration in a developing station (30) of a printer is disclosed. The adjustment is performed by calculating the thermal drift of a dry ink monitor (40) and applying the result as a compensating factor in calculations in a software algorithm. The dry ink monitor (40) has a sensing port (42) in contact with a dry ink concentration and is connected to a dry ink monitor interface board (10) that houses a temperature sensor (20). The monitor interface board (10) is positioned in proximity to the dry ink monitor (40) to enable the temperature sensor (20) to measure a temperature of the dry ink concentration. The software algorithm is used to adjust the dry ink concentration based on a slope coefficient calculated by the printer based on outputs from the dry ink monitor (40) and the dry ink monitor interface board (10).
