Abstract: In one example, a method for wiping the face of a printhead includes wiping across the face of the printhead and then wiping along the face of the printhead with a web of cleaning material. In another example, a wiper for wiping a face of a printhead includes a rotatable shaft having an axis of rotation and a helical blade affixed to the shaft. The helical blade is simultaneously rotatable on the shaft against the face of the printhead and translatable along the face of the printhead in a direction parallel to the axis of rotation.
