  • Publication number: 20180065825
    Abstract: A sheet handling apparatus for a printing system includes a rotary drum having an inner chamber circumferentially surrounded by an outer peripheral wall with perforations formed therein. By means of sucking an air flow through the perforations of the drum to a suction system, sheets are attracted to the peripheral wall of the drum. A stationary shutter member is positioned inside the inner chamber for blocking the flow of air through the perforations when they pass, with the rotation of the drum, through a first predetermined angular range. The shutter member includes protrusions while the rotary drum includes recesses for receiving the protrusions, such that a meandering air flow passage is formed between the shutter member and the rotary drum. As such, friction between the rotary drum and the stationary shutter member is reduced, thereby reducing the power consumption of the suction system.

  • Publication number: 20180056650
    Abstract: In the method for controlling actuators, corresponding actuators are controlled so that they eject the ink droplets for the print image. Corresponding actuators are additionally controlled in order to eject refresh droplets in the image background according to a random distribution. In the event that no image droplet is printed between two successive refresh droplets, the ink meniscus is set into vibration as a refresh measure between the refresh droplets.

  • Patent number: 9889685
    Abstract: Methods to exchange printing substrate rolls in a printer are described. In an exchange method, ink is printed to a first printing substrate web being unwound from a first printing substrate roll. The first printing substrate web is exchanged with a second printing substrate web being unwound from a second printing substrate roll. A transition region of the first and the second printing substrate webs is printed to during the exchange of the first and the second printing substrate webs. The transition region can be formed by gluing the second and the first printing substrate webs atop one another. A predetermined pattern can be printed onto the transition region during the exchange of the printing substrate rolls. The predetermined pattern can be chosen such that all nozzles of at least one print head are used for printing.

  • Publication number: 20180029360
    Abstract: In an a method to stabilize the ink meniscus at a nozzle opening of a nozzle of a print head including the nozzle and one or more adjacent nozzles to the nozzle, the nozzle can be induced to generate a signal pulse at an activation time. The signal pulse can be a pre-fire pulse (e.g. a negative pressure reduction pulse), where, for example, no ink is ejected. The inducement to generate the pulse can depend on the number of adjacent nozzles that eject ink at the activation time. The negative pressure in the nozzle can then be reduced, and nozzle failures due to air suction may be avoided.
