Riso SF9490 Ink

The Riso SF9490 is a digital duplicator that can print up to 190 sheets per minute.
It's the world's fastest digital duplicator.
The SF9490 can print on paper sizes ranging from 3.5" x 5.5" to 11" x 17". However, it can't print full bleed, so you'll need to add a 1/4 -1/2 inch border to prints and booklets.
The SF9490 is a monochrome duplicator. It has a short paper path and an easy-to-master panel.
Riso Kagaku Corporation, a Japanese corporation, invented, manufactures, and distributes the RISO Printer-Duplicator.
