Provided is an evacuation device for an inkjet printing device that is designed to guide a printed recording medium along a transport direction through a constriction with an opposite gas flow, in order to be able to efficiently and comprehensively evacuate ink vapor before the constriction, in terms of the transport direction.

Device and method for evacuation of ink vapor

In a device for supplying a printing substrate web to an internal transport path of the printing substrate web of a printing device, a device accepts the printing substrate web from the printing substrate web source. A drive unit is provided at an output of the device and draws the printing substrate web from the device. A buffer device having a buffer reservoir is provided at an output of the drive unit. The buffer reservoir has a negative pressure device that generates a negative pressure in a buffer reservoir. The negative pressure acts on the printing substrate web to pull the printing substrate web drawn by the drive unit into the buffer reservoir and thereby tensions the printing substrate web before it is supplied to the internal transport path.

Device for feeding a printing-material web to an electrographic printing device

A transfer printing station is provided with a transfer roller for transfer of a toner image generated on an intermediate carrier onto at least one recording medium in a transfer printing region of the transfer printing station. A drive unit causes the transfer roller to move towards the intermediate carrier as an ON position or away from the intermediate carrier as an OFF position, the drive unit being designed such that it is position-controlled when moving towards the ON position, and is torque controlled in the ON position.

Transfer station for an electrographic printer or copier

The invention relates to a transfer printing station for an electrographic printer or copier wherein the transfer is carried out by means of a transfer roller () that simultaneously forces a web of paper () against a photoconductor drum () in such a manner that no defective spots (data loss) or bright spots in scanning patterns, indefinite scanning patterns and horizontal stripes in scanning patterns occur on the paper web (). This is especially important for the subsequent printers of a system of printers that have to print onto a paper that is stressed by the fixing station of the preceding printer. The transfer roller () is disposed in a swiveled support unit () that comprises, in addition to the guide of the paper web (), transfer jaws () along the photoconductor drum (). The inventive transfer printing station is especially suitable for use in printing systems with a plurality of printers or copiers.
