Abstract: PROBLEM TO BE SOLVED: To enable a copying machine which is complex and multifunctional to achieve effective trouble-shooting by easily and automatically indicating a trouble part. SOLUTION: The output of a sensor is used as direct and indirect data, and further used for the detection of the trouble part of the device. For example, the calibration 120 of a black-toner-area coverage degree sensor is carried out through measurement in a soil-free state as in unused state, and soil-level check 126 is carried out. Further, a light-receiving-body patch uniformity test 128 is performed for determining the defective area of the surface of the electrophotographic light-receiving-body. Thereafter a beam fault test 136 for a raster output scanner (ROS) and cleaner test 138 are performed. Also, as a comprehensive actuator-performance-indicator-test, a preliminary-electrification test block 140 and an ROS test 142 are carried out. These are followed by a background test 144 and so on. By these various tests, the trouble part is detected. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To realize efficient trouble shooting by evaluating the performance of an electrifying sub-system and easily and automatically detecting it as for a complicated multi-function copying machine. SOLUTION: Three kinds of halftone patches (12%, 50% and 87%) are formed by setting a valve to a nominal value and executing electrifying, exposure and developing actions. Then, the reflectivity of the special patches are measured (228). When the reflectivity RRD is larger than '120' and a extremely bright response is shown (230), it is judged that the problem of power supply or the like is caused (232). When the reflectivity RRD is smaller than '120' and larger than '60' (234), it is judged that a problem such as the defective action of a donor roll is caused (236). When the reflectivity RRD is smaller than '60' and larger than '35' and a dark response is shown (238), it is judged that a problem such as the lowering of toner concentration is caused (240). When the reflectivity RRD is smaller than '35', the extremely dark response is shown and it is judged that a developing system is being actuated without causing the defective action.

Abstract: PROBLEM TO BE SOLVED: To provide a method for discriminating deteriorated parts in an electrophotographic process. SOLUTION: This method consists of a step to generate a first signal by detecting one part 378 of an image pickup surface 370 at the position where it is not affected by the actuation of an electrifying member 372, a step to generate a second signal by detecting the number part 380 of the image pickup surface at the position where it is affected by the actuation of the electrifying member 372, a step to compare the first and second signals and a step to discriminate the number part of the image pickup surface deteriorated by corresponding to the step to compare the first and second signals.

Abstract: PROBLEM TO BE SOLVED: To easily and automatically detect a fault in a laser beam and to make efficient troubleshooting as to a copying machine which is complex and multifunctional. SOLUTION: A raster output scanner(ROS) exposes and develops pixels on a photoreceptor to form an image. The picture elements have a proper energy distribution generated with proper copy quality. If, however, the ROS is defective in operation, the energy distribution becomes distorted and the copy quality deteriorates. A special patch of a horizontally striped pattern and a special patch of a vertically striped pattern are generated and developed (262, 266) respectively, read by a BTAC(black toner area coating degree), and recorded (264, 268). When pixels are correctly formed, to each patch equal energy is given, but if pixels are distorted, the value of one patch is different from that of the other. Therefore, when '|horizontal patch-vertical patch| > target' (270) is satisfied, it is decided that the ROS has the possibility of malfunctioning (272).

Abstract: PROBLEM TO BE SOLVED: To easily and automatically detect a fault in a laser beam and to make efficient troubleshooting as to a copying machine which is complex and multifunctional. SOLUTION: A sensor is calibrated (180) and the reflection factor RR100 of a 100% clean patch on a photoreceptor is recorded (182), special patches are arranged by only lasers A and B of double laser beams (188, 184) and the relative reflection factors RRA and RRB of those patches are recorded respectively (190, 186). When the lasers A and B are normal, they have nearly 50% halftone reflection factors. When RRA and RRB are larger than a given threshold value based upon RR100 (196, 192), it is decided that the lasers A and B are out of order (198, 194). When neither of the lasers A and B is out of order, it is considered that both beams are normal (200).

Abstract: PROBLEM TO BE SOLVED: To attain efficient trouble shooting by easily and automatically detecting the failure of a photoreceptor in a copying machine having complicated multiple functions. SOLUTION: A photoreceptor patch uniformity test 128 is executed as one of tests for detecting the failure. In the test, a sample is obtained every 1.5 mm in the whole of the surface of the photoreceptor by a black toner area covering level sensor (BTAC). Seam detecting algorism is used, a seam sample is thrown away and a value for showing the total uniformity of a cleaning belt is calculated from the residual samples. This value is used as a reference value. Since the position of a seam is judged, the position of each process control patch and a corresponding BTAC reading value can be analyzed. An average and dispersion are obtained in each patch and compared with the reference value. The uniformity of each position is calculated by a statistical analysis and compared with the reference value. When the uniformity is lower than its permissible level, an operator is informed of the exchange of a belt.

Abstract: PROBLEM TO BE SOLVED: To provide a general purpose system for exchanging information between a module and a device around the periphery of a printer/duplicator. SOLUTION: A panel board 30 executes a mutual operation with a memory device called CRUM(customer replaceable unit monitor) which is specified for coupling with one or plural customer replaceable modules in a device. An electrophotography module 10 and a fixing module 12 are designed to be customer replaceable so that each of them can be taken off from the device as it is, then it can be replaced to another one of the same kind. A customer can buy or lease the individual module, if necessary in order to replace it therewith. The electrophotography module 10 is coupled with a CRUM 11 and the fixing module is with a CRUM 13. Integral purpose of the CRUM 11 and CRUM 13 is for holding information about an operational condition and a using situation of the module in the device. The held data is periodically updated and the data is maintained even when the module is removed from the device.
