Abstract
A cleaning pad that is part of a printer developer customer replaceable unit cleans a laser aperture each time the customer replacement unit is removed and/or replaced. The pad is located on an inboard end of the customer replaceable unit such that when inserted into the printer it wipes any accumulated toner from the surface of the laser aperture. Also, in developer units that include a light proof cover that retracts at the time of insertion, the wiper is situated so that it cleans the aperture in the process of retracting.
