ABSTRACT:
A device for storing a supply of particles for use in one of a first developer unit of a first electrophotographic printing machine and a second developer unit of a second electrophotographic printing machine is provided. The device is cooperable one of a first mechanism of the first developer unit of the first electrophotographic printing machine and a second mechanism of the second developer unit of a second electrophotographic printing machine to feed the particles from the device into one of the first developer unit and the second developer unit. The first mechanism includes a first mechanism feature and the second mechanism includes a second mechanism feature. The device includes a container defining a chamber for storing particles therein. The container defines an aperture therein. The first mechanism further includes a first member removably connectable to the container. The first member includes a first member feature. The first member feature when connected to the container is engagable with the first mechanism feature. The first member feature when connected to the container prevents engagement with the second mechanism feature. Wherein the device may be mounted into the first printing machine and be utilized to feed the particles from the device into the first developer unit and wherein mounting of the device into the second printing machine is prevented.
