When the developer housing assembly of a copying machine 1s removed for cleaning, a "sump sucker" or contamination control vacuum hose often must be disconnected. Usually this hose is full of unused toner which is laying loose inside the hose so that when the hose is disconnected, toner falls out into the machine where it contaminates the adjoining machine mechanical components Sometimes the loose toner falls onto the floor and dirties the clothes of the person servicing the machine.
