ABSTRACT:
A printhead module is provided with a printhead chip and at least one passageway that supplies air to the printhead chip. A valve is included to open and close the passageway and hence the supply of air to the printhead chip. The valve may be operated by or be part of a capping device that caps the printhead chip, so the valve is closed when the capping device caps the printhead chip.
