  • Method and controlling means for regulating the position of a band-shaped image carrier in an electrographic apparatus
    Patent number: 6721528
    Abstract: A method and apparatus for controlling a lateral position of a band-shaped intermediate image carrier in an electrographic apparatus by regularly detecting a mark on the intermediate image carrier with a sensor. The band-shaped intermediate image carrier is moved in a transport direction from an image generating position at which an image is generated on the image carrier to a transfer position at which the image is transferred. A transverse position of the intermediate image carrier relative to the transport direction is detected and is time correlated with the regular detection of the mark. Intermediate position detections are carried out between the regular detections of the mark in a time-controlled manner. The detected positions are compared to stored position values or calculated theoretical position values and the results of the comparison is used to control position correction devices which change the transverse position of the intermediate image carrier.

  • Communication arrangement in electrographic printer and copier device
    Patent number: 6122462
    Abstract: A unified bus system is used for communication in a printer or copier apparatus. Each functional unit of the printer or copier apparatus is connected to the bus by an interface. The interface includes a duel-port RAM memory unit in which data messages associated with the specific functional unit or sensors in the printer or copier apparatus are stored. The functional units are notified of the presence of new data or messages on demand so that each functional unit has an overall picture of the functional status of the printer or copier.

  • Device for monitoring the operation of a fixing station of an electrographic printing device
    Patent number: 5978613
    Abstract: An apparatus is provided in a printer to prevent wrapping of the paper web onto the printer's fixing roller which fixes the toner particles onto the paper web. The apparatus includes a sensor to monitor the speed and moving direction of the web at the output of the fixing station. The sensor is connected to a controller which operates to halt the operation of the fixing station or the printer when the sensor senses a reversal of the moving direction of the web. The controller may average the web moving speed and compare the average speed to a predetermined speed for halting printer operation if the average speed traverses the predetermined speed.
