Abstract

An isometric schematic view of a residual toner collection bottle 10 and level sensor assembly 12 is shown in the accompanying Figure. A plastic cradle 14 vertically guides and holds the bottle. The cradle houses the level sensor assembly which comprises a coaxial magnetic plunger 15 that resides in a cylindrical core 16. As the bottle weight increases with accumulated residual toner, the weight overcomes the magnetic force which tends to thrust the plunger upwards. When the bottle is substantially full, the conductive surfaces 18,20 of the plunger and core bottom, respectively, meet and a signal to the electrophotographic copiedprinter control panel is generated indicating the bottle is full. The bottle is reduced to a smaller opening 22 for a toner inlet via tube 24.

As the bottle weight increases with accumulated residual toner, the weight overcomes the magnetic force which tends to thrust the plunger upwards. When the bottle is substantially full, the conductive surfaces 18,20 of the plunger and core bottom, respectively, meet and a signal to the electrophotographic copiedprinter control panel is generated indicating the bottle is full.
