Abstract

1414319 Recovering residual electrostatic toner XEROX CORP 19 Dec 1972 [30 Dec 1971] 58570/72 Heading G2H An electrostatic reproduction apparatus, such as an electro-photographic copier, includes means by which residual toner powder is removed from a printing or reproduction surface and passed to a weighing machine where it accumulates in supported containers 60. If an excessive amount of toner is allowed to accumulate in one or more container, a switch is operated to prevent further accumulation. Preferably residual toner is conveyed through duct 32 in suspension in air, and is separated by centrifugal force in separator 40.
