Abstract
An inkjet waste ink handling system embodiment of the present invention includes a spittoon reservoir for collecting waste ink dropped from an inkjet printhead, and a ramp within the spittoon reservoir having an upper end that receives any ink dropped in and a lower end to which gravity conveys such ink. In this way, pillars of dried ink are prevented from accumulating.
