ABSTRACT:
A kit used in TC measurement in the field includes a sandwich of 3 screens used for filtration of carrier beads from toner particles within a container. An upper 400 mesh screen has die-cut holes around its edges to allow removal of any beads trapped between the upper screen and a middle 500 mesh screen. A bottom screen of coarse 20 mesh material is used for strength to support the other screens. When a vacuum source connected to a bottom portion of the container is turned ON, the carrier beads approach the screens in the center of the container. The recirculating airflow carries the carrier beads away from the upper screen at the edges. Thus, with the upper screen being die-cut with openings around its edges, these openings allow the trapped beads to return to the inner chamber of the container for removal during cleaning.
