Cascade Liquid Toner

This is a liquid toner for exposed electrostatic paper. Paper 10 in drawing A, charged side up, enters the first set of feed rolls 12 and is directed toward drum
14. At the top of drum 14 the leading edge of This is a liquid toner for exposed electrostatic paper. Paper 10 in conform to the surface of drum 14. Just before the leading edge leaves guide 16, rubber O-rings 18, drawing B, come in contact with its sides and hold it to drum 14. As the leading edge passes nozzles 20, the latter cascade toning liquid 22 over the charged side. The cascade continues until the trailing edge reaches a point about one quarter of an inch above the level of nozzles 20. Paper 10 is conveyed past heater 24 which evaporates any liquid remaining and melts the toner particles, thus fixing them. Before paper 10 reaches the top of drum 14, O-rings 18 release it. Fingers 26 of guide 16 drop between disks 28 below the level of paper 10, causing it to pass over the top of drum 14 and be emitted by roller 30.
