Abstract

A waste ink removal system cleans ink residue from an electrostatic sensing element of an ink drop detector in a printing mechanism when a scraper, supported by a base, is actuated between a retracted position and an engaged position. The system also includes a debris receptacle and/or an absorber which the scraper contacts, after scraping ink from the sensing element, to remove the ink from the scraper surface. A method of cleaning ink residue from an electrostatic sensing element of an ink drop detector, and a printing mechanism having such a waste ink removal system are also provided.
