Abstract

Proposed is a replaceable waste toner bottle that mounts directly under a cleaner assembly employed in an electrophotographic printing machine. Typically, waste toner is stored in two different ways for current low and mid-volume products. For low volume blade cleaner applications having a Customer Replaceable unit (CRU), toner is frequently stored in a cleaner sump that is part of the CRU. When the CRU is replaced, a new and empty sump is provided. In mid-volume blade cleaner applications, toner is transported by an

auger to a waste bottle that is located at a remote location. The Unit Manufacturing Cost (UMC) for blade cleaner systems may range from $30 to $60, with an auger transport system accounting for approximately 25 percent of the cost. The low cost blade cleaner waste system is especially attractive for mid-volume applications as a way to eliminate the auger and corresponding drive components.

Figure 1 illustrates the location of waste container 30 adjacent to a vertically mounted photoreceptor belt 10 and below cleaner assembly 20. The waste container 30 is designed as a CRU and slides in the direction indicated by arrow 40 for removal. The vertical architecture of photoreceptor 10 maximizes a container h/d ratio to correspondingly maximize the fill efficiency of waste container...
