Abstract
A vacuum attachment tool and method for using the tool is provided with a fluidizing nozzle, a screen holder having a screen with a predetermined mesh size, and a venturi for increasing the speed of air and particles passing through the screen. The tool is particularly useful for sampling dry toner particles from large supply hoppers and filtering out 'coarse' particles. This tool can readily determine locations having oversized particles and is provided with several attachments that aid in collection. The tool is readily attachable to a vacuum hose of a vacuum source.
