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.

Inkjet printhead squeegee

A method for wiping a printhead of an inkjet printing mechanism is provided. During a wiping process, firstly, a first amount of wiping force is exerted on the printhead for wiping the printhead in a first direction. Subsequently, a smaller amount of wiping force is exerted on the printhead for wiping the printhead in a second direction opposite to the first direction. The potential damages on the printhead by a dry wiping can thus be decreased by controlling the wiping force on the printhead.
