Method and apparatus for determining a minimum pressure to print |
摘要 |
A printer consumable includes an ink bag, and a supply of ink included within the ink bag, and optionally a memory device and a pressure sensor. The pressure sensor communicates an ink bag pressure loss measurement through a communication means to an ink delivery system. The communication means uses the ink bag pressure loss measurement to determine a minimum pressure to print. In one embodiment, the communication means periodically polls the pressure sensor to acquire the ink bag pressure loss measurement and records the measurement on the memory device of the printer consumable. When the communication means receives a print job, the measurement is acquired from the memory device to determine the minimum pressure to print before the print job is processed.
