ABSTRACT:
A copier/printer having a transfer station for transferring images from an imaging member to copy sheets includes the improvement of removing debris from within the copier/printer by locating baffles and vacuum ports within the copier/printer to cause deposition, collection and removal of debris and other contaminants in specified locations. An electrical bias is selectively applied to at least some of the baffles to electrostatically attract the contaminants thereon. The vacuum ports are connected to a vacuum source that could operate continuously or intermittently at start-up or shutdown.
