Digitally compensated pressure ink level sense system and method

摘要

A printing system (50) includes an inkjet printhead (60A) for selectively depositing ink drops on print media (40). An ink reservoir (110A) stores ink to be provided to the inkjet printhead. An ink level sensing circuit (110C and 700) provides an ink level sense output that is indicative of a sensed volume of ink in the ink reservoir. A memory device (706) stores sensor compensation information. A processor (80) responsive to output of the memory device and the ink level sense output generates a compensated ink level sense output. The processor provides an estimate of available ink based on the compensated ink level sense output. <IMAGE>
