摘要
An ink delivery system for an inkjet printer includes: a positive ink line having a controlled positive ink pressure; a negative ink line having a controlled negative ink pressure; one or more print modules interconnected between the positive ink line and the negative ink line via respective inlet and outlet lines. Each print module includes: a printhead; a control valve positioned at an inlet port of the print module 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.
