Abstract
An inkjet printer comprises an inkjet printhead and an ink reservoir contained in a pressurizable chamber, with an ink conduit interconnecting the ink reservoir and the printhead. An air compressor is in fluid communication with the chamber and a valve is positioned between the air compressor and the chamber. A first air conduit interconnects an outlet of the air compressor and the valve, while a second air conduit interconnects an inlet of the air compressor and the valve. The valve is switchable between a first configuration in which the valve interconnects the outlet and the chamber via the first air conduit, and a second configuration in which the valve interconnects the inlet and the chamber via the second air conduit.
