Abstract
A pressurized ink delivery system having two delivery reservoirs in an inkjet printer enables a control system to alternate between the two reservoirs for printhead supply without coupling pressurized air from a delivery reservoir to a low pressure source of ink. Each delivery reservoir includes a conduit having an orifice that enables the pressure within a delivery reservoir to exit the reservoir before the ink delivery reservoir is fluidly connected to the low pressure source of ink for refilling of the delivery reservoir. By dropping the high pressure reservoir to atmosphere and then switching the seal actuators for the two reservoirs, the spray of ink is avoided.
