Abstract
A multi-tiered, multi-faceted, anti-flicking wiper scraper system cleans an inkjet printhead wiper without flicking or splattering ink residue onto other components in an inkjet printing mechanism. This system includes a scraper apparatus supported by a service station frame to contact the wiper through relative motion of the wiper and scraper apparatus. The scraper apparatus may take the form of two scraper bars which extend into the path of the wiper, with the first scraper bar being shorter than the second scraper bar, and with the first scraper bar being rigidly or pivotally supported by the frame. The scraper apparatus may be a unitary body defining two ramped wiping surfaces joined at an apex portion of the body, or a body having a scraping surface covered with a series of ridges. A method is also provided to clean ink residue from an inkjet printhead.
