Copierlprinter machines store used toner cleaned from the machine photoreceptor in a remote sump. This toner is transported there through a system of passages, some of which contain rotating augers. Where a high volume of prints is run, a problem may occur as a result of these passages becoming clogged. Because toner in these passages show signs of blocking, it is suspected that the problem is in part temperature related.
