  • Image forming control method using variable state factors and fuzzy computation
    Patent number: 5231452
    Abstract: An image forming method for forming an image by transferring toner image formed on a photoconductive element to a paper sheet or similar recording medium. Variable factors affecting image transfer, paper separation and paper transport characteristics are classified. An image transfer state, a paper separation state and a paper transport state are each estimated as a combination of membership functions of the variable factors to determine an image transfer condition, a paper separation condition, a paper transport condition and auxiliary conditions such that control is executed on the basis of the determined conditions.

  • Electrophotographic process control device using a neural network for estimating states of the device
    Patent number: 5220373
    Abstract: An electrophotographic process control device for an electrophotographic image forming apparatus. A neural network is incorporated in the control device for estimating the state of the image forming unit. Parameters of the kind which should not be frequently measured, e.g., the surface potential of a photoconductive element and the amount of toner deposition thereon and parameters which are not easy to measure are determined by inference so as to control each section of the apparatus in an optimum way.
