A printing unit prints to a pre-folded substrate web. An intake unit is at an intake of a transport arrangement. A synchronization sensor is at the transport arrangement between an infeed roller and the printing unit. The synchronization sensor emits a synchronization signal when a fold of the web is present at the synchronization sensor for synchronization of a printing operation with feed of the web. A path between the synchronization sensor and a freely accessible point of the intake unit is designed such that a fold is present at the synchronization sensor when the printing substrate web has a fold at the accessible point. A relative humidity sensor is at the printing unit. A relative humidity measured by the sensor is compared with a relative humidity of an input stack. Given a deviation a length change of the web between the synchronization sensor and the accessible point is calculated, the web being displaced by the length change at the accessible point.

Ink printing apparatus, and method to control the driving of a printing apparatus

In a printer system composed of a plurality of printer devices, the speed of the recording medium to be printed and of the intermediate carrier in every printer device following a printer device is adapted to the changing dimensions of the recording medium. For example, the changes in the recording medium that occur due to the fixing of toner images on the recording medium and that lead to a degradation of the print image are considered in following printer devices.

Arrangement for setting the speed of an intermediate carrier in an electrophotographic printer device

A printer or copier has a transfer printing station for electrostatic transfer of toner from a photoconductor to the recording medium. A pressure contact element is provided on the recording medium guide elements to ensure contact of the recording medium with the photoconductor during transfer. Supporting rollers of a slightly greater diameter than the pressure contact element are provided at each end thereof bearing on the photoconductor as spacer elements to define a minimum spacing between the pressure contact element and the intermediate carrier. The contact pressure element(s) may also be mounted on pivotable levers movable by an eccentric.
