Abstract: A mechanical schematic diagram showing the paper flow path through a xerographic copying machine and an associated sorter is illuminated when a paper jam occurs or when the supply of paper, toner or fuser oil is depleted. At the same time the copier is shut down and a flashing light on the diagram at the approximate location of the problem source is illuminated. Steadily illuminated lights indicate the positions of paper sheets which must be removed from the machine before normal operation can resume. Depleted consumable items are also identified by flashing lights indicating the location of the cause of the interruption. Thus the machine operator is immediately able to determine the cause of the interruption and the corrective action required.

Abstract: A process for manufacturing a xerographic toner cartridge containing a heat-fusible toner powder situated in a container having an open end surrounded by a peripheral lip. An elongated tongue of a material having non-directional shear strength characteristics is placed on top of the opening, with a thermoplastic adhesive layer being disposed between the container lip and the tongue. The adhesive is activatable by heat and pressure, and once activated adheres more strongly to the peripheral container lip than to the tongue. The adhesive is bonded to the tongue and the peripheral lip by a heated platen having a shape conforming to that of the lip. The heat and pressure applied is sufficient to form the desired adhesive bonds, but the temperature and time employed are insufficient to cause deterioration of the toner powder in the container.
