An ink supply system for an inkjet printer. The ink supply system includes an ink reservoir and a pressure-regulating chamber. The pressure-regulating chamber has an inlet port, an outlet port, an air vent open to atmosphere and a float valve for maintaining a predetermined level of ink in the chamber. The float valve is biased towards a closed position by a positive ink pressure from the ink reservoir at the inlet port.
