  • Automatic Standard Envelope Size Detection

    The paper feed tray automatically detects standard envelope sizes, so customized registration is not required.

  • Easy Guidance for Changing Consumables

    Reading the QR code attached on the duplicator body with a smart device leads to an instruction video on RISO's YouTube channel showing how to replace the master roll and ink cartridge, and empty the master disposal box.

  • Paper Memory Print

    Paper Memory Print is useful when it is difficult to print directly from a PC or use a USB memory. Also, converting original data into a digital pattern improves confidentiality and helps prevent information leaks. This function easily converts original data created on a PC into a “Paper Memory Data” digital pattern. Scanning the data, the SF EII series retrieves the original data by decoding the digital pattern, achieving the same high quality of output image as that being processed through the PC.

  • Ink Color Variations

    21 standard colors, 50 custom colors and special order-made colors are available. A wide range of printing colors can meet the needs of a variety of print jobs.

  • Usage Reporting
