Abstract: A wide format printer that has a print zone where droplets of ink print onto media, a drive roller configured to translate the media into the print zone and a movable media engagement assembly for vacuum engagement of one side of the media to draw the media away from the print zone wherein, the print zone is more than 432 mm (17 inches) wide.

Abstract: A printing system that has a drive roller for feeding different sizes of media along a media path, an inkjet printhead assembly for printing the media and an ink aerosol collection system for removing ink aerosol from areas adjacent the media path. The ink aerosol collection system is configured to remove aerosol at a greater rate in response to an increase in the media size.

Abstract: A wide format printer that has 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 wherein the print zone is more than 432 mm (17 inches) wide.

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 fluidically coupled to the first and second conduits and, a bypass line coupling the feed line to the return line.

Abstract: An inkjet printer that has a print zone, a media path 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 and a plurality of interfaces for supplying ink to, and receiving ink from each of the printhead modules respectively.

Abstract: A printing system that has an ink supply, an accumulator reservoir, a valve coupling the accumulator reservoir to the ink supply, the valve being configured to open when the ink level in the accumulator reservoir reaches a lower limit of a predetermined ink level range, and close when the ink level in the accumulator reservoir reaches an upper limit of the ink level range, and a plurality of printheads in fluid communication with the accumulator reservoir.
