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 wide format printer 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 collectively spanning a paper path more than 432 mm (17 inches) wide, each of the printheads being in fluid communication with the accumulator reservoir and each of the printheads having nozzles for ejecting ink onto media. During printing, the accumulator reservoir is fixed relative to the printheads such that hydrostatic ink pressure at the nozzles is generated by the elevation of the ink level in the accumulator reservoir relative to the elevation of the of the nozzles.

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 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 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.
