Abstract (en)
[origin: WO9409412A1] A pneumatic toner transport arrangement for an electrophotographic printing or copying machine is useful for transporting toner and for removing toner and/or dirt particles from units of the machine, such as the developing station (10) and the cleaning station (28). The arrangement has a negative pressure generator (31) connected to the various units of the machine by a negative pressure duct system. A particle separator (24) designed as a cyclone filter for separating toner and dirt particles from a throughflowing air flow is associated with the duct system. The particle mixture is separated in a recycling arrangement into dirt particles and recyclable toner and the recyclable toner is once again supplied to the developing station. The dirt particles are collected in a fine filter (32) of the negative pressure generator (31). The toner recycling arrangement (25) is designed as an exchangeable module which can be exchanged for a collecting container.
