Abstract

A tool is proposed for cleaning the inside of a photoreceptor drum serving as a waste toner sump in a Customer Replaceable Unit (CRU). A re-manufacturing process requires that the wasted toner be removed before recycling the drum. As shown in the accompanying figure, the drum cleaning tool comprises an air wand 10 mounted to a base plate 12. The air-wand 10 is connected to a vacuum (not shown) through a passageway 14 and a valve 16. The process for cleaning a drum (not shown) is to place it over air wand 10 and locate it on base plate 12. The vacuum is always in the "on" position and the air flow is actuated by an operator controlled foot switch (not shown). Air flows for approximately 10 seconds as the drum is manually rotated to ensure that the inner surface is cleaned.
