ABSTRACT:
A printer comprising a printhead and a pressure-regulating chamber containing ink at a predetermined first level relative to the printhead. The chamber comprises an outlet port, a return port positioned in a base of the chamber, a snorkel extending from the return port and terminating at a snorkel outlet positioned above the first level of ink, and an air vent open to atmosphere. An upstream ink line interconnects the outlet port and an ink inlet of the printhead. A downstream ink line interconnects the return port and an ink outlet of the printhead. The downstream ink line has a section looping below the first level of ink. In a printing configuration, a second level of ink in the snorkel is equal to the first level of ink in the chamber.
