Abstract
An inkjet printing system, including an inlet in a print head to receive ink from an ink supply, a plurality of nozzles to eject ink in the print head, an ink pressure sensor disposed in an ink path, the ink pressure sensor configured to determine an ink pressure of the ink in the print head and output a signal indicating the ink pressure, and a controller in the print head configured to receive and process the signal indicating the ink pressure from the ink pressure sensor. The inkjet printing system may also include a memory to store an ink pressure and time profile. The controller may also output a signal to stop ejecting ink from the plurality of nozzles when the ink pressure is either below a negative threshold or above a positive threshold.
