A method for operating a jetting module includes applying to a drop forming mechanism a sequence of drop formation waveforms in which a small-drop waveform applied after another identical small-drop waveform causes a small drop of volume Vs to be formed; applying a large-drop waveform after another identical large-drop waveform causes a large drop of volume VL to be formed, and applying a large-drop waveform adjacent to a small-drop waveform can be done in a way that produces a large drop having a volume VL2, where VL2 is different than VL and a small drop of volume VS2, where VS2 is different than Vs.

摘要:
In a method and system to generate a print image on a carrier material, the surface of a print substrate is covered with at least one of an ink-repelling and an ink-attracting layer. In a structuring process, ink-attracting regions and ink-repelling regions are generated corresponding to a structure of the print image to be printed. An ink-attracting carrier substance is applied which can be an ink or other carrier substance on the print substrate surface that adheres to the ink-attracting regions and is not accepted by the ink-repelling regions. The carrier substance is fixed and subsequently the fixed carrier substance is inked with ink at least once. The applied ink is transferred to the carrier material. Before a new structuring process, the print substrate surface is cleaned and newly covered.

摘要:
In a method to remove toner deposits on a surface of a cleaning element, electrically charged toner particles are transferred from a carrier surface to an intermediate carrier. On the cleaning element, untransferred, electrically charged toner particles as residual toner from the carrier surface are received. Electrically charged toner particles on the cleaning element are directed past an electrode arrangement arranged at a distance from the surface of the cleaning element. An alternating electrical field is generated which acts on the toner particles to loosen them. The toner particles remaining on the surface of the cleaning element are brought into contact with a mixture of carrier particles and toner particles during further transport along a transport direction of the cleaning element.
