Abstract: A method and apparatus for delivering toner in sealed containers to a developing system in an electrophotographic machine. Toner is sealed in flexible containers which are connected in a belt-like manner so that toner can be supplied continuously in discrete amounts to the developing system. The belt of sealed toner containers travel from a toner supply housing to an extractor unit where the containers are opened, allowing the toner contained therein to fall to the developing system. The depleted toner containers continue to travel to a take-up member where they are stored. Generally, the depleted toner containers are removed from the take-up member and discarded when a new supply of toner is added to the toner supply housing. This sealed container system allows for a large supply of toner to be stored anywhere in the electrophotographic machine and for the toner supply to be replaced very cleanly.

Abstract: A measuring apparatus for determining the appropriate level of magnification to reproduce a document onto an output sheet with pre-determined dimensions is disclosed. The device may be mounted to the surface of the copy machine or it may be attached to the side of the platen glass. The original document is properly lined up with the measuring device, and horizontal and vertical magnification factors are read from both sides. The smaller of the two values is then entered into the magnification system of the copy machine. This will allow an original document of any size to be copied onto a sheet of paper with pre-determined dimensions. Several devices may be used together to form a set to allow the user to determine the appropriate magnification factor for a copy sheet with virtually any dimensions.
