A method for configuring the further processing of printing substrates in a digital printing machine includes modifying settings for configuring the further processing while the machine is in operation. The settings of the further processing are created by using a configuration program running on a control unit of the digital printing machine. The modified settings have an effect on at least one region to be further processed on the printing substrate and the settings are printed onto the printing substrate so as to be allocated to a corresponding region to be further processed.

A method for operating a cleaning apparatus, having a trough and a brush disposed in the trough, in a printing press, includes first, second and third steps. In the first step, a cylinder of the printing press is cleaned by the cleaning apparatus, with the brush bearing against the cylinder. In the second step, the brush is moved away from the cylinder, and a level of a liquid in the trough is changed, resulting in the liquid being brought into contact with the brush. In the third step, the brush is cleaned by the liquid in the trough. A printing press for carrying out the method is also provided.

An apparatus for driving a roller of a printing press includes a main motor configured to drive the roller through a first gear wheel and a first freewheel, and an auxiliary motor configured to drive the roller through a second gear wheel and a second freewheel. A brake that is different from the main motor, for example a band brake, is configured to brake the roller during overrunning of the roller following a machine stop signal. A printing press having the apparatus is also provided.

A method of depositing sheets coming out of a sheet-processing machine includes decelerating the sheets and depositing the sheets of a main pile. Certain sheets are decelerated and fed to a second sheet pile. The system includes a device for decelerating the sheets arriving from the sheet-processing machine and for depositing the sheets on a main pile. A chain gripper system is configured to hold and decelerate a trailing edge of the sheets. The chain gripper system includes an adjustable gripper opening cam.

An apparatus for ejecting sheets from a sheet transport path onto an auxiliary stack disposed upstream of a main stack, includes a planar sheet guide surface having a sheet ejection opening formed therein. The sheet ejection opening is closed by a sheet separating element and a flap, in a closed state. The separating element and the flap also serve as guide elements during the ejection of sheets.
