Abstract: A device and a method are provided for recharging a belt conveyor which is used for transporting a printing medium in the transfer area of an electrophotographic printer or a copying machine. The device includes a blade-like contacting element which is adjacent to the belt conveyor and arranged transversally with respect to the forward motion thereof. The contacting element makes it possible to transfer an electric charge to the belt conveyor and is mounted on a bearing element which can be inserted into a printer or a copying machine and withdrawn therefrom. A method is provided for controlling a printer or copier device by which errors, such as paper jams, can be cleared automatically. A controller commands a module having the error to clear the error automatically. The commands are sent to modules beginning at the output of the printer or copier device and moving in a reverse direction to the paper flow direction of the printer or copier so as to automatically clear errors such as paper jams.

Abstract: In a method and system for transfer printing of an electrostatic recharge toner image from an intermediate carrier onto a recording medium and for fixing of the transfer-printed toner image onto the recording medium, the recording medium lying on an electrostatically-chargeable conveyor belt and adhered thereto by electrostatic forces is transported through a transfer printing region and subsequently along a guided transport section. The recording medium is conveyed to a fixing device. The guided transport section is arranged in a transport unit and the fixing device is arranged in a fixing unit which are independent of one another. The fixing unit has at least one wall designed to hinder a heat transfer from the fixing unit to the transport unit.

Abstract: A device for electrically charging a transport belt for transport of recording media in a transfer printing area of an electrographic printer or copier as well as a method for charging. In a direction transverse to a running direction of the transport belt, a contact element is arranged bearing against the transport belt and via which electric charge is transferred to the transport belt, the contact element comprising a contact lip which is substantially comprised of a rubber material and which bears against the transport belt.

Abstract: In a method and system for operation of a transfer printing station of an electrographic printing device, a transfer printing station is provided comprising a light-sensitive medium onto which toner images are provided by electrostatic forces affected via a toner image electrical potential. A transport band is provided holding successive sheet-form recording medium by electrostatic forces. Toner images are transfer printed from the light-sensitive medium onto the successive sheet-form recording media by electrostatic forces affected by an electrical transfer printing potential. The electrical transfer printing potential is at least reduced while the light-sensitive medium passes into intervening space line between two successive recording media sheets. A cleaning station cleans off residual toner on the light-sensitive medium that is not transfer-printed. A cleaning device mechanically loosens residual toner from the transport band.
