Abstract: A portion of a xerographic development material is slowly circulated past a vertically oriented porous wall where it serves as a filter for airborne toner particles flowing therethrough. Toner enriched development material is returned to the main body of development material for reuse. Toner particles cleaned from residual xerographic images are conveniently transported by airflow entrainment to the development material filter.

Abstract: TEST CYCLE QUALITY CONTROL SYSTEM FOR AN ELECTROPHOTOGRAPHIC MACHINE A system for checking copy quality variables within the image area of an electrophotographic machine. During a test cycle, quality is checked by producing sample test areas within the photoconductor image area ordinarily used for producing copies. Reflectance measurements are made on sample test areas and compared to a dynamically floating reference achieved by a reflectance measurement from a cleaned portion of the photoconductor within the image area. The testing circuit is balanced so that the same reflectance voltage should be generated whether the single reflectivitysensing device is viewing a sample test area or a cleaned reference area. The system can be used to check for quality variables such as toner concentration, image voltage and an abnormally low reflectance photoconductor and provides a check on its own fault-free condition during periods when it is not in use.
