In an electrophotographic printing machine, it is frequently highly desirable to automatically replenish used photoconductive belts with unused photoconductive belts. One such approach for the automatic replenishment of photoconductive belts

employs a magnetizable sub-belt 10 entrained about a pair of opposed, spaced rollers 12. In order for this technique to be operable, the photoconductive belt must have a magnetic layer. The magnetic layer may be an additional layer or may replace the usual ground layer. In order to load the first photoconductive belt, sub- belt 10 is magnetized by energizing magnetizing head 14. A new photoconductive belt is advanced from cassette 16 and is attracted to sub-belt 10 magnetically. The belt trail edge overlaps the lead edge when replenishment is complete. After the photoconductive belt has been used for the desired number of reproductions, it may be replenished by actuating de-magnetizing head 18. This eliminates the magnetic attractive force between sub-belt 10 and the used photoconductive belt. Stripper fingers separate the lead edge of the used photoconductive belt from sub-belt 10. Forwarding rollers 20 move the lead edge of the belt into cassette 22. Thereafter, sub-belt 10 is re-magnetized and a new photoconductive belt is magnetically

secured thereto as hereinbefore described.

Alternatively, the phot...
