摘要： A digital printing machine includes a printing bar for inkjet printing. The printing bar is mounted to be movable into a working position and into a retracted position. An adjustable roll and a spring-mounted roll form a first assembly and are disposed opposite one another. A rail forms a second assembly and is located between the adjustable roll and the spring-mounted roll when the printing bar is in the working position and is not located between the adjustable roll and the spring-mounted roll when the printing bar is in the retracted position. One of the two assemblies is disposed on the printing bar and the other of the two assemblies is separate from the printing bar.

摘要： A digital printing machine includes a printing material transport device, an inkjet print head having a nozzle plate, and a capping element. The inkjet print head is adjustable into a first print head position relative to the capping element and the capping element is adjustable into a capping position relative to the inkjet print head. The capping element temporarily covers the nozzle plate when the inkjet print head is in the first print head position and the capping element is simultaneously in the capping position.

摘要： A method for avoiding collisions in a digital inkjet printing machine, a method and a device for actuator-based lifting movement of inkjet heads. A sensor/camera monitors the sheets as they travel towards the inkjet heads. In order to avoid collisions, the inkjet heads are raised and lowered again individually and in an oscillation-optimized manner when a defective sheet is detected. The machine does not need to be stopped in the event of defective sheets. Advantageously, rejects can thus be reduced and the performance of the machine can be exploited better.
