A method for heating and fixing an inking, particularly a toner powder on a plate-shaped support. Heat is applied and fixes the inking to a coated upper side of the support. The method of this invention can be used to fix and adhere toner inkings on thick-walled supports. In one method step of this invention, the coated upper side and/or an uncoated underside of the plate-shaped support each is subjected to infrared radiation and/or a hot air stream and/or a microwave radiation. At least a portion of the infrared radiation and/or the hot air stream and/or the microwave radiation directed onto the uncoated underside of the support passes through while another portion is absorbed, such as if the support has a high weight per unit area of the support. A ceramic or thermosetting toner forms the applied ink.

Method and device for heating and fixing an inking, particularly a toner powder on a plate-shaped support

An electrophotographic printing device with a developer unit and a photoconductor. The photoconductor is either directly connected to a substrate to be printed in the region of a transfer zone, or is connected by an intermediate circuit of one or several transfer media. At least one charger is provided for the substrate and the substrate may be transported through the transfer zone by a transport device. According to this invention, an effective transfer of toner to the substrate surface can be achieved with such an arrangement, even with a poor electrically-conducting and thick-walled, sheet-like substrate, whereby a charger is arranged as the primary charger in the transport direction and a secondary charger is arranged in the region after the transfer zone and both primary and secondary chargers affect the surface of the substrate to be printed.

Electrophotographic printing device

A printing machine with an electrophotographic device, having a photoconductor, a photoconductor drive and an illumination device. The electrophotographic unit can be provided with the substrate by a feed device. The photoconductor drive motor is adjusted by a controller and the feed device can be linearly adjusted by 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 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.

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

A device for printing on paper or plate-shaped materials, such as plates made of glass, ceramic, glass-ceramic or plastic materials, having a transport device for the plates to be printed and an electrostatic, in particular an electrographic, printing device arranged above it. With the printing process of this invention, in an efficient manner, a conveying and centering unit of a screen-printing device is combined as a transport device with the electrostatic, in particular the electrographic, printing device, which is compatible with the upper unit of the screen-printing device.
