Abstract
A print module configured for interconnection between a positive ink line and a negative ink line via respective inlet and outlet lines. The print module includes: an inlet port; an outlet port; a printhead interconnected between the inlet port and the outlet port; a control valve positioned at the inlet port for controlling an ink pressure in the printhead; an ink pressure sensor for sensing an ink pressure in the print module; and a controller for receiving feedback from the pressure sensor and controlling the control valve. During printing, the ink pressure sensor, the controller and the control valve cooperate to control a backpressure in the printhead within a predetermined backpressure range.
