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.

Inkjet printing system having dynamically controlled ink reservoir

An inkjet printing system includes an ink reservoir defining a longitudinal axis, an ink-receiving chamber and a control chamber. A control fluid source delivers a control fluid across a range of pressure levels to the control chamber, and an orientation sensor determines an orientation of the longitudinal axis of the ink reservoir and generates an orientation signal. A processor is operably coupled to the control fluid source and the orientation sensor, the processor being programmed to infer an angle of the longitudinal axis relative to the vertical reference axis based on the orientation signal from the orientation sensor, determine a desired pressure for the control chamber based, at least in part, on the inferred angle of the longitudinal axis, and control the control fluid source to adjust the actual pressure level in the control chamber to the desired pressure for the control chamber.
