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.

Abstract: A laser lens cleaner and cleaning method for a compact-disc playing machine having a turntable-like compact-disc support, a laser-reading device with a laser lens facing the reflective playing surface of a compact disc, a motor for rotating the compact-disc support, and a control circuit for receiving instructions from a compact disc or a cleaning disc relative to rotating and stopping the compact-disc support. The cleaning disc is the same size as a compact disc for the playing machine. It has a reflective lower surface with a cleaning brush projecting out downwardly therefrom for contacting the laser lens. The cleaning disc also has digital, electrically coded data providing a portion containing instructions for the control circuit. The instructions instruct the control circuit via the laser lens what to do during rotation of the cleaning disc and to stop the cleaning disc when the laser lens has been cleaned.
