Abstract: A wide format printer that has a print zone, a media path more than 432 mm (17 inches) wide and extending through the print zone along a paper axis, a printhead carriage with a plurality of printhead mounting sites for mounting a plurality of printhead modules adjacent the print zone such that the printhead modules collectively span the media path, the printhead carriage having a long side extending transverse to the paper axis, the long side having access formations for ink conduits and a plurality of interfaces for connection to the ink conduits to supply ink to each of the printhead modules respectively. All ink for the plurality of printhead modules is supplied by ink conduits extending through the access formations on the long side of the printhead carriage.

Abstract: A printing system with a drive roller configured to engage and push media into a print zone and a movable media engagement assembly configured to engage one side of the media and pull the media while the drive roller remains engaged with the media.

Abstract: A printing system that has a media feed assembly for feeding different sizes of media along a media path, the media path having a width corresponding to a maximum width of media that can be printed by the printing system. The system also having a printhead assembly positioned on a first side of the media path and spanning the width of the media path, an aerosol collection duct with an opening on the first side of the media path and a spittoon system positioned on a second side of the media path opposing the first side. The printhead assembly is configured to eject non-printing ink drops from any section not required to print media that is less than the maximum width, and the spittoon system is configured to collect the non-printing ink drops.

Abstract: A wide format printer that has an inkjet printhead assembly for printing media fed along a media path that is more than 432 mm (17 inches) wide, and an aerosol collection system for collecting ink aerosol generated by the printhead assembly. The printhead assembly is positioned on a first side of the media path and the aerosol collection system has a first aerosol collection opening positioned on the first side of the media path and a second aerosol collection opening positioned on a second side of the media path.

Abstract: A wide format printer that has a media transport system configured to transport media of differing dimensions along a media path, and a printhead assembly for printing media transported along the media path, the media path having variable widths depending on the dimensions of the media but a minimum width of 432 mm (17 inches). The printer also has a plurality of service modules for the printhead assembly, each being configured to operate in a plurality of different modes. The media path extends between the printhead assembly and at least some of the service modules configured to operate in one of the modes while any of the service modules beyond the media path operate in another of the modes.

Abstract: A printing system that has a print zone, a drive roller positioned at an input side of the print zone, a vacuum platen assembly positioned under the print zone, a printhead assembly overlaying and spanning the print zone and a vacuum belt assembly configured to receive media from the print zone.

Abstract: A wide format printer that has a printhead assembly for printing media fed along a media path, the media path being more than 432 mm (17 inches) wide, and a plurality of service modules for the printhead assembly. Each of the service modules is configured to operate in a plurality of different modes and each of the service modules are independently operable.

Abstract: A wide format printer that has an ink supply, a feed line coupled to the ink supply, a return line coupled to the ink supply, a plurality of printheads collectively spanning a paper path more than 432 mm (17 inches) wide, the printheads each coupled to the feed line and the return line and, a pumping system to generate a pressure difference between the feed line and the return line during a printhead replacement operation.

Abstract: A printing system that has an ink supply, a first conduit coupled to the ink supply, a second conduit coupled to the ink supply, a plurality of printheads each coupled to the first conduit and the second conduit and a pumping system to generate a pressure difference between the first conduit and the second conduit during a printhead replacement operation.

Abstract: A wide format printer that has an ink supply, a feed line coupled to the ink supply, a return line coupled to the ink supply, a plurality of printheads collectively spanning a paper path more than 432 mm (17 inches) wide, each of the printheads being coupled to the feed line and the return line and, a pumping system configured to generate fluid flow from the feed line to the return line via the printheads to prime the printheads.

Abstract: A method of printing by translating media across a print zone at a first speed based upon the angular velocity of a drive roller and subsequently translating the media at a second speed determined by a movable media engagement assembly configured to engage one side of the media.

Abstract: A printing system that has a print zone, a media path extending through the print zone along a paper axis, a printhead carriage for mounting a plurality of printhead modules adjacent the print zone such that the printhead modules collectively span the media path and are staggered with respect to the paper axis, the printhead modules each having nozzles arranged in parallel rows and a plurality of datum features for holding the printhead carriage such that the parallel rows extend normal to the paper feed axis.

Abstract: A device for retaining a valve bridge is disclosed. The valve bridge is engaged with a plurality of valves. The device has a first base member. The first base member is configured to engage at least one of the plurality of valves. The device also has a first latching member. The first latching member extends from the first base member. The first latching member is configured to engage and retain the valve bridge in engagement with the plurality of valves.
