the CRU. The process requires about 25 to 30 seconds per CRU. The furture's vacuum arrangement is superior to a centralized system because of its reduced cost.

As shown in the accompanying figure, furture 10 comprises a vertically oriented platen 12 having dimensions A and B of approximately 22 inches and 9 inches, respectively. CRU housing 16 is placed upright on platen 12 and held thereto by perpendicular columns 14 that align a toner sump opening (not shown) in the housing with nozzle 20. Nozzle 20 connects by way of hose 22 to an external shop vacuum (not shown). A motor 24 located on furture 10 engages an idler gear (not shown) on housing 16 and rotates a sump paddle therein to loosen the waste toner. The simultaneous action the motor 24 and the vacuum removes the toner from housing 16.
