Single Pass Dual Color Printing

The RISO ME6350 digital duplicator comes with dual drums. Compared to using single-colour digital duplicators for two-colour output, this reduces ink-drying time and the tasks of reinserting paper and changing drums. One simple action gives you the high-speed colour printing you need. (Single-colour printing using one drum is also possible.)

High Speed Printing @ 150ppm

The RISO ME6350 features an adjustable five-speed function for printing between 60 and 120 pages per minute. It also has a high-speed mode that prints at a maximum speed of 150 pages per minute, or approximately 750 pages in five minutes.

High Quality 

Sharp, rich images give your ideas the desired impact on the page

The RISO ME6350 digital duplicator both scans and prints information at a high resolution level of 600 dpi, producing sharp, clear images of even fine lines and small characters. The model uses the RISO Master E Type HG, with a two-layer ink-permeable sheet adding an extra fine-filter layer to the standard layer, enabling even ink transfer to the paper. It can also reproduce subtle colour gradations, enabling users to print clear copies of photos, shaded areas of images, and documents written in pencil.

High Quality Printing

Overwhelmingly Economical Print Costs

The RISO ME6350 first creates a master copy of the original document, from which prints are made. The printing cost per copy of a document goes down with every print, making the RISO ME6350 highly economical for large-volume printing. You can use the optional “A4/letter drum” to print these popular sizes even more efficiently to save master usage, holding down running costs to a minimum.

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
