摘要： A modified UTOPIA interface for inter-board applications is provided where the address timing generated by a polling master is extended to be two clock cycles long with no NULL address being driven onto the address line in between addresses. Output and input circuitry is provided in conjunction with the polling master and user ATM boards to accommodate hot insertion and to help drive the circuit. The master preferably includes an outgoing address latch and address latch control associated with the address bus, and a register associated with the enable signal. The master also includes a hot insertion buffer on the incoming cell available signal. The user device(s) include hot insertion buffers on the address bus, the data bus, and the enable signal. A remapping function is also preferably provided in associated with the user board which permits the user board to map received addresses into desired addresses. With the extended address timing and the provided circuitry, a workable inter-board hot-insertable UTOPIA interface is established.

摘要： The present invention relates to the remote activation of a system diagnostic for a customer. The system so activated is resident at the customer location. The activation is initiated at a location remote from the customer location. The activation of the diagnostic may also include correction and optimization of the system if it is determined that it is needed. Any such initiated system activity would most typically be performed after hours. The system then communicates locally to the customer the diagnostic results as found, as well as any other action taken.

摘要： During the operation of a document processing system machine and job data are collected from a document processing system. Optionally, machine information, both for the specific machine and population based data are acquired from a database or server. Having accumulated the job data and machine data, the diagnostic inference engine performs an analysis to determine the initial diagnosis of the document processing system. After obtaining the initial diagnosis, the system determines the test patterns to be printed and the image quality tests to be performed. The system then prints test patterns, and scans the patterns to determine image quality parameters and/or to automatically identify image defects. Optionally, image defect information may also be provided by the customer or the service engineer via a user interface. Next, a diagnostic inference engine uses the results of the image quality analysis to refine the initial diagnosis. Then, the diagnostic results are output, stored, and optionally displayed to, for example a customer or a customer service engineer. Based on the diagnostic results, and if problems are found, the machine enters a repair sequence. In particular, the machine can request either a customer or a customer service engineer repair action, or, alternatively, enter an auto-correction or an auto-calibration mode to repair itself. Upon completion of one or more, or any combination, of these repair actions, the machine verifies its operation and again checks to ensure the repairs have been completed successfully.

摘要： A toner concentration sensing system is disclosed for controlling the dispensing of toner into a developer sump. A toner concentration sensor is located in the bottom of the mixing area of the developer sump adjacent one of the mixing augers. The toner concentration sensor can be positioned flush with the bottom of the mixing chamber or the sensor can project slightly from the bottom of the chamber. A magnet is positioned on the rotating mixing auger for rotating with the auger past the toner concentration sensor. As the auger rotates, the magnet with developer material adhering thereto, sweeps the top of the toner sensor to improve the accuracy of the toner concentration readings. A toner dispenser is actuated when the detected toner concentration goes below a predetermined limit.
