Abstract
An inkjet printhead squeegee is split on one side so that its wiping force on a printhead is highest on the front stroke and much lighter on the backstroke when the surface is dry. Alternatively, the split can be arranged so that the front stroke is light enough to leave the printhead wet, and then the backstroke is much firmer to completely squeegee the printhead dry. The result is high pressure strokes on a dry printhead are avoided.
