RISO MF9350 Dual color printer



High-quality two-color printing makes
RISO your ideal partner

RISO is renowned globally for the reliability of its digital duplicators. It is the only company in the world that offers two-color digital duplicators, and is now proud to introduce its most advanced two-color model yet. The MF9350 sets a new gold standard for productivity, cost performance, image quality and operability. Its two-drum layout makes two-color printing faster and easier than ever, with versatile options that are suitable even for small-volume print runs.

Single Pass Dual Color Printing

RISO MF series employs a single-pass layout, for faster and more efficient two-color printing. Unlike using single-color digital duplicators for two-color output, there’s no need to wait for ink to dry, reinsert paper or change drums.

Overwhelmingly Economical Print Costs

The MF series makes prints from a master. As a result, the more pages generated from each master the lower the cost per print, making it highly economical for medium- to high-volume printing.

Numerous Input Options

For users who create originals on a PC, the printer driver software automatically handles colour separation when the data is sent to the printer. Even if the printer is not connected to your PC or network, you can still print directly from your data file. Just save the file to a USB flash drive, connect the flash drive to the printer via the built-in USB port, and you’re ready to print. And of course you can print from copies scanned directly into the unit.

Print from hard copies, a computer, a USB drive, or stored data.

Various Color Options

The machine’s colour drum accommodates a wide variety of inks in 21 standard colours, 50 custom colours, plus special order-made colours that can give corporate logos an extra-special look. This huge selection of colours lets you add powerful impact to your documents. And because the ink is made by RISO, you’re assured of the highest quality results. Front panel access makes switching the drum quick and easy to change colour, too.

Simple and Reliable Security Features

By registering the names and PIN codes of authorised users, access can be restricted and misuse prevented. Instead of a PIN code, a USB flash drive*1 can also be used for authentication and registration.*2 The Protect function displays a message asking the user to transfer the master to the Master Disposal Box after printing is completed. For additional security, it is also possible to use a padlock to secure the Master Disposal Box.*3
