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.
