ABSTRACT:
A method and device for handling an endless, flexible, articulated belt of photoconductive material. The belt is continuously moving, and a housing is provided to store the greater portion of the belt which is not being run through copier machinery. A pair of feed rollers feeds a quantity of belt material returning from the copier machine to the housing, and a pair of dispensing rollers are synchronized with the feed rollers so as to eject a like quantity of belt material to the copier. Therefore, although the portion of the belt within the housing is continuously changing, the unit mass of material within the housing remains substantially constant. The photoconductive belt is uniquely fan-folded within the housing to provide a compact bundle of material, and the bundle is made to reciprocally translate within the housing, as the belt is fed to, and dispensed from, the housing. The dispensed photoconductor generally undergoes an imaging process comprising the steps such as: (a) charging; (b) exposing; (c) developing; (d) transferring; and (e) cleaning; etc.
