Like all Risographs, versatility is built into the FR3950, from printing on a wide variety of paper sizes and weights, to multi- and spot-color printing, and to multi-up printing. Internal soundproofing reduces noise as the FR3950 prints up to 120 pages per minute. And with the optional interface capabilities with RISO's full line of system controllers, the FR3950 connects to your stand-alone or networked Window or Macintosh computer. What else would you expect from the world leader in the development of digital duplicating technology?
