摘要:
A method of assembling a print head that includes the steps of: (a) providing a print head base including a nozzle and at least one ink channel; (b) mounting in fluid communication with the at least one ink channel of the print head base an ink regulator that includes: (i) a pressurized chamber including an ink inlet in fluid communication with an ink source, an ink outlet in fluid communication with the at least one ink channel of the print head base, and an exterior flexible wall having an inner surface facing an interior of the pressurized chamber, (ii) a valve biased to restrict fluid communication between the ink source and the pressurized chamber, where the exterior flexible wall actuates the valve to overcome the bias in response to a predetermined pressure differential across the exterior flexible wall to provide fluid communication between the ink source and the pressurized chamber, where the fluid communication between the pressurized chamber and the ink source decreases the pressure differential across the exterior flexible wall and, where the valve restricts fluid communication between the ink source and the pressurized chamber when the pressure differential across the exterior flexible wall is less than the predetermined pressure differential; and, (c) positioning an ink filter in fluid communication with the ink regulator and the at least one ink channel of the print head base.
