Abstract

A waste ink removal system cleans ink residue from an ink drop sensor 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 reservoir defining a plurality of capillary drains onto which the scraper deposits ink residue while moving to the engaged position. 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.
