Continuously feed up to 975 documents using three standard feeders in cascading mode. Increase capacity to 1200 sheets with an optional high-capacity feeder. Utilize the vertical stacker for quick unloading of filled envelopes.


Document feeders accommodate a wide variety of material combinations from full sheets to short inserts. This flexible and scalable inserter is available in three configurations and designed to fit perfectly into any work environment.
