  • Patent number: 10589546
    Abstract: A web printing apparatus comprising a support platen facing the processing station for supporting the web, when being processed by the processing station and a first guard for guarding a side edge of a web, the first guard being connectable to the support platen for guiding the web along a transport path, when the web is processed by the processing station. A detector is provided for detecting the first guard when connected to the support platen as well as a control unit configured for controlling the processing station to process the web, wherein the control unit is configured to identify the guard based on a detection signal provided by the detector to the control unit. Thereby, the first guard is identified by the control unit which may then control the movement of the print carriage to avoid the first guard, preventing collisions.

  • Patent number: 9284151
    Abstract: In order to enable simple and easy handling of a large number of large format sheets, an output assembly is provided. The output assembly comprises a lower output tray element for receiving the sheets. In order to reliably transport and deposit a large format sheet from the printing device onto the lower output tray element, a guide element is provided just below an output opening of the printing device such to guide a leading edge of the sheet onto the lower output tray element. Once the leading edge is supported by the lower output tray element, the guide element is retracted such to enable a trailing edge to be deposited on the lower output tray element.

  • Patent number: 7140706
    Abstract: A system for adjusting the angular orientation in a first plane of a plurality of print head cartridges or groups of cartridges arranged adjacent to each other on a carriage which can be reciprocated in a Y-direction, wherein each of said cartridges or group of cartridges is mounted on said carriage to be tiltable in said first vertical plane, wherein for each of said cartridges or groups of cartridges said carriage is provided with first adjustors for adjusting the angular orientation of the respective cartridge or group of cartridges, said system being provided with second adjustors arranged remote from said carriage for adjusting said angular orientation of said cartridge or group of cartridges, said second adjustors selectively, operatively communicating with said first adjustors of a selected one of said cartridges or group of cartridges.
