摘要： A cleaning system for increasing the packing density of a cleaner sump that uses magnetic toner, by filling unused sump space. The cleaning system uses a magnetic force to attract the magnetic waste toner to the sump area not filled by gravity assistance alone. The magnetic force is created by a magnet. The magnet can be either internal to the sump or external thereto.
