摘要： A method of performing maintenance on a printhead of an imaging device includes the application of a purge pressure to ink in an on-board reservoir of the printhead to cause ink to be burped through a plurality of apertures in an aperture plate of the printhead. A wiper blade is then dabbed on the aperture plate at least once after the application of the purge pressure. After the dabbing, the wiper blade is drawn across the aperture plate. The wiper blade is then dabbed against the dabbing position at least once after wiping the aperture plate.

摘要： A method detects weak or missing ink jets in an ink jet image generating system. The method includes generating a digital image of a test pattern of line segments in a process direction on an image receiving member with each line segment corresponding to one ink jet in a printhead, generating a response profile for a portion of the image receiving member on which the test pattern was generated, measuring the response profile, comparing the measurement of the response profile to a predetermined threshold, identifying missing and weak ink jets in response to the measurement of the response profile being less than the predetermined threshold, and moving the support member transversely across the process direction to a second position that enables each light sensor to image another portion of the image receiving member.
