SF9490 Digital Duplicator

Produce More Jobs

At speeds up to 190 sheets-per-minute, the SF9490 is the world’s fastest digital duplicator. The short paper path supports a wide range of paper stocks to deliver legendary RISO reliability.

Automate Production

The new Plug-and-Print capability automatically and immediately prints one or multiple saved jobs from USB flash drives without the need for additional user intervention.

Enhanced Image Quality

Improved cylinder motion controls and advanced printer driver algorithms deliver smoother ink transfer and overall increased image quality.

Minimize Short-Run Printing Costs

A new ink saving mode reduces ink usage by up to 20% for cost-conscious customers and higher profit margins.

Increased Job Flexibility and System Dependability

Rotate pages 180 degrees at the click of a button to reverse the lead-edge for jobs with high-density coverage, increasing paper feed reliability and reducing page-to-page set-off.

Envelope Feeder Accessory

The Straight Shooter envelope feeder provides continuous load and unload capacity for envelopes ranging in size from 3” x 5” to 6.5” x 13” and heavy paper stocks up to 110lb index.

Build on offset capabilities and move into digital printing with the SF9490

The SF9490 provides an easy first step from analog offset to digital printing. The simple copier-like user interface and operation make the SF9490 intuitive and fast to learn so you’ll be producing high-quality output within minutes.

  • Like offset, the SF9490 uses liquid ink while electrophotographic copiers use dry toner.
  • The SF9490 uses masters in the printing process. RISO masters are manufactured from an organic material—a major environmental benefit.
  • Masters are automatically exposed like CTP, plus automatically loaded and unloaded like on advanced DI offset presses.
