A reproduction apparatus imaging material dispensing system has a replaceable and rotatable imaging material dispensing container from which an at least partially magnetically aitractable consumable imaging material is dispensed. There is an optical imaging material level sensing system mounted outside of the container for optically detecting the imaging material inside the container through translucent walls thereof and signaling an insufficient remaining quantity of imaging material. A magnetic brush cleaning system internally cleans imaging material from the inside of a annular translucent wall area of the container to provide and maintain relatively unobstructed such optical sensing. It can be provided by a stationary magnet mounted outside of but adjacent to the container to attract magnetically attractable imaging material to the inside of the container wall to form a magnetic cleaning brush to clean the translucent wall annular area. This allows a light receiving sensor on one side of the container to detecting light from a light emitter on the other side of the container through the magnetically cleaned translucent annular band. The magnet can extend substantially the full length of the outside of the container to clean the entire interior thereof.

A development system for a reproduction machine includes a pair of augers which mix and transfer the developer mixture to a magnetic roll brush system. A supply auger having a length at least as great as said magnetic brush roll is positioned along a horizontal plane and adapted to transport developer material in a direction so as to supply said material to said magnetic brush roll. The auger has a first portion thereof having an irregular blade edge and wedge shaped paddles to eliminate auger mark print defects.

A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device includes an open ended container defining a chamber in communication with the open end of the container with the particles being stored in the chamber of the container. The container defines an aperture in the container spaced from the open end and an air permeable cover closely conforming to the aperture for containing the particles within the container.

A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device includes an open ended container which has a chamber in communication with the open end of the container. The particles are stored in the chamber of the container. The device also includes a feature associated with the container which extends substantially the length of the container, for urging the marking particles in the chamber toward the center of the chamber.

Clean finned toner cartridge

A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device includes an open ended container defining a chamber in communication with the open end of the container. The particles are stored in the chamber of the container. The device also includes a puncturable seal attached to the open end of the container for sealing the chamber. The container is installable into the developer unit without removal of the seal. The device further includes an internal seal attached to the open end of the container. The internal seal is internal to the puncturable seal. The internal seal has a surface closely conforming to the open end of the container. The internal seal is removable from the open end of the container by displacement of the internal seal into the chamber of the container.

An apparatus for gripping the leading edge portion of a sheet includes a first gripping member which substantially spans the leading edge portion of the sheet. The apparatus further includes a spring having a portion thereof defining a second gripping member which substantially spans the leading edge portion of the sheet, the second gripping member being urged toward the first gripping member to grip the sheet.

Sheet gripping mechanism

An apparatus for effecting electrical connection between the main machine and a module containing the apparatus for advancing a sheet through the transfer zone and to registration for information developed on the photoreceptor belt. The connector on the main machine is mounted to permit engagement with a complementary connector on the module, but provide for movement when the module is raised slightly to contact the photoreceptor module. The apparatus minimizes which otherwise would inhibit this upward movement and detract from proper operation of the machine and the quality of the copy produced.

A registration transport and transfer module is located in a retractable drawer having a camshaft actuated by a lever. Rotation of the lever turns the cam which cooperates with a mounting to enable the transfer module to be lowered beneath a photoconductive belt. The drawer may then be pulled away from the machine and the transfer module pivoted about a point so as to expose portions of the copy sheet path for jam clearance.
