Characterization of the different modes of Traveling Wave Toner Transport (TWTT) is advanced through the use of improved measurement techniques, including a direct time-of-flight determination of particle speeds. Using these techniques, the attractive speed characteristics of the recently predicted “Hunching Mode” (HM) of transport is confirmed. Space charge, however, appears to severely limit the mass flows attainable in the HM. Mass flows in the “Surfing Mode” (SM), on the other hand, have been extended to exciting new levels, exceeding 25 mg/(cm-sec) - enough to develop or print more than 50 ppm. New approaches to powder cloud development and direct printing based on the SM of TWTT are indicated and referenced.
