Abstract: An electrophotographic printing or copying machine includes a functional module which can be readily removed and replaced by service personnel. The module includes a monitor in the form of an electronically-readable memory, which includes information about how the particular module is to be operated. A distribution board electronically accesses the memories within the monitors and reads therefrom information, such as how much voltage to supply to different components within each module. The distribution board can also update the number of prints made with each module, and maintain this count within the monitors.

Abstract: A compact dual decurler mechanism that provides a single straight paper path for achieving bidirectional decurling capability. The dual decurler mechanism consists of two pairs of drive roll and pinch shaft and a camming mechanism for controlling their engagements. The first and the second pairs are oriented in opposite directions in a manner that they can selectively form opposite bending nips for decurling incoming sheets of different curl directions. The operation of the dual decurler can be software controlled through the use of an electric indexing clutch such that, depending on system inputs on image area coverage and the type of finishing device being used, the first pair can be adjusted for toward image (TI) bending, the second pair for away image (AI) bending, or both be set at a neutral setting that keeps both nips open when no decurling is needed. The architecture of the single straight paper path of the dual decurler can minimize paper jams and avoids potential damage to sheets.

Abstract: An agglomerate spot cleaning blade is supported to cleaning housing, thereby forming a substantially enclosed chamber, in sealing engagement with respect to the photoreceptor surface. Contact is maintained between a cleaning brush, located within a cleaning housing, and a blade, whereby rotating brush fibers remove accumulated agglomerate debris particles from the blade. A substantially air-flow free environment is maintained for removal of residual toner and debris from the photoreceptor surface and the blade, without the need for a separate vacuum/air removal system assist, or a separate manual maintenance step.

Abstract: An apparatus which cleans a photoconductive surface having residual charged particles of opposite polarities thereon. Oppositely electrically biased cleaning brushes remove particles from the photoconductive surface with each brush being located in the chamber of a different housing with each housing electrically biased to the same magnitude and polarity as the brush located within the housing. The particles are then attracted from the cleaning brushes to electrically biased detoning rolls.
