Patent number: 6350006Abstract: An apparatus and method for monitoring operation of an ink jet printhead. An ink jet printer is controlled to eject a periodic sequence of ink jet curtains through an illuminated gap. Variations in the intensity of the illumination caused by the ink jet curtains are detected to generate a signal representative of the opaqueness of the curtains. The signal is compared to a reference and if insufficient opaqueness is detected a poor print quality signal is generated. In one embodiment a feedback loop is established during a calibration mode to adjust the nominal level of illumination.Type: GrantFiled: November 17, 1998Date of Patent: February 26, 2002Assignee: Pitney Bowes Inc.Inventors: Arno Muller, Eswaran C.
