Abstract

In a toner dispenser in an automatic reproducing machine, the toner dispensing rate is in part a function of the toner sump level. As the toner sump level decreases, the dispensing rate decreases. This is particularly significant for small copiers where the space set aside for the toner dispenser is comparatively small thereby potentially leading to decreased dispensing rate. It has been found that the pore condition of the open celled foam dispensing roll to a large entent control the toner dispensing rate. The figure illustrates a device for alleviating this difficulty. The toner dispenser indicates a toner hopper 10 with two individual side walls 12 forming a chute at the bottom of which is a rotatably driven open celled foam toner dispensing roll 14. The side walls meet the foam dispensing roll so as to pinch the foam forming a seal on the one hand and to "flick" the toner off the roll on the other hand when a portion of the foam roll cears the side wall restriction.

TONER DISPENSER TENSION ROD (Cont'd)

To assist in altering the surface tension/compression characteristic of the foam roll a tension rod 16 in contact with the foam dispensing roll is placed inside the toner hopper which produces tension in the foa...
