Abstract
An inkjet printing system includes an ink reservoir defining an ink-receiving chamber and a control chamber, a control fluid source fluidly communicating with the control chamber, and an orientation sensor configured to determine an orientation of the ink reservoir and generate an orientation signal. A processor is operably coupled to the control fluid source and the orientation sensor, the processor programmed to determine a desired pressure for the control chamber based, at least in part, on the orientation signal, and control the control fluid source to adjust an actual pressure level in the control chamber to the desired pressure for the control chamber.
