Filed: 1972-12-18
Abstract: 1409578 Electro-photographic apparatus XEROX CORP 18 Dec 1972 [23 Dec 1971] 58249/72 Heading G2H An electro-photographic printing apparatus incorporates a toner dispenser which is a hopper with a reciprocating grid 42 at its base, driven in one direction by a cam on a rotating shaft 61 and in the other by springs 55, with a stroke determined by the extent to which movable stop 56 allows rod 58 to contact the cam. When the operator moves lever 64, the position of the stop 56 is adjusted. Normally the lever rests against a second stop 75, and the stroke of the reciprocating grid is such that a standard amount of toner is dispensed with every rotation of the shaft 61 and of the drum to which it is linked. If a lower rate of dispensing is required, the lever may be made to over-ride the second stop. When a higher rate is required the lever is moved away from the second stop, the stroke of the reciprocating grid is increased, and a further mechanism actuated by rotation of the shaft 61 is brought into operation to return the lever, and hence the stop 56 by stages to its starting position, each stage being actuated by a revolution of the shaft 61 and associated e.g. with the production of a toner image. In place of alteration of the setting in response to the production of toner images, other production criteria may be used to control the rate of change of the operator-selected setting.
