Printing machine with adjusting device for synchronizing the photoconductor speed and feed guides speed by means of a master-slave controller and control of the scanning speed of the exposure unit

摘要

The invention relates to a printing machine with an electrophotographic device, comprising a photoconductor, a photoconductor drive and an illumination device. Said electrophotographic unit can be provided with the substrate by a feed device. The photoconductor drive motor is adjusted by means of a controller and the feed device can be linearly adjusted by means of a feed device drive motor. In order to produce high-definition prints, especially images or lettering on plate-shaped substrates, the feed device drive motor is adjusted by means of a controller that is controlled by a master-slave controller via a setpoint feed. The controller for the photoconductor drive motor is also controlled by the master-slave controller via a setpoint feed and the master-slave controller synchronizes the feeding speed of the feed device and the speed of movement of the photoconductor.
