Abstract
A machine optics and paper path cleaner has a relatively stiff backing sheet and a cleaning sheet attached to the backing sheet at a position spaced from the leading edge. The cleaning sheet is folded, flocked or flapped, knitted or engraved with surface variations to aid in the cleaning of paper paths and optics. Wet cleaners are held in absorbent materials and in frangible or openable reservoirs to wet the cleaning material as it is drawn into the machine through the paper path and across the optics. The cleaners are made in single foam sheets of varied thickness and in laminated sheets of stiff backing material and flexible cleaning material.
Claims11
A machine optics and paper path cleaner implement, comprising a stiff backing sheet and a flexible non-absorbent cleaning sheet attached to the backing sheet, the flexible cleaning sheet having a raised cleaning surface, the backing sheet and the cleaning sheet having rectangular planforms with a leading edge and a trailing edge and opposite side edges, the raised cleaning surface of the cleaning sheet being ridged and having increased flexibility and loft with respect to the stiffness and thickness of the backing sheet, a cleaning area of the cleaning sheet extending from a start of the cleaning area between the side edges of the sheets to the trailing edge of the sheets.
