CHAPTER 2. MACHINE OVERVIEW
1. Features

Simultaneously prints two colors at speeds up to 120 sheets per minute.
The RISO V8000 uses its screen printing system to achieve both speed and economy in printing.
The two print drums print simultaneously for easy two-color printing at speeds of 120 sheets per
minute. Per page printing costs are even lower with greater print quantities. The cost of printing 1,000
copies is 173 yen, or approximately 0.17 yen per print.

High print quality with 600 dpi high resolution and V-Press
The machine incorporates a “V-Press” configuration, with two print drums arranged in a V-shape
relative to the paper drum, for outstanding print quality and precise print positioning. Pressure is
applied from each print drum to the paper drum, which retains precise, positive control of paper
position to the ejection stage by gripping the ends of the paper, ensuring the precise print positioning
required for two-color printing. The machine incorporates Riso Kagaku’s extensive experience with
high-quality image output, with variable pressure print drums capable of fine control of ink density and
600 dpi resolution.
‹ ‹ ‹ ‹ ‹
Combined two-color printing capability
A dedicated printer driver enables colorful printing with two-color printers. One of the machine’s major
features is the ability to print color photo documents with combined two-color printing for dramatically
improved image quality compared to previous single-color tones.
‹ ‹ ‹ ‹ ‹
Network compatible, with a monitoring function to track operations
on-screen
The RISO V8000 can be networked for high-speed, high-quality output of document data created on
PCs. The monitoring function allows monitoring of RISO V8000 status (e.g., standby, in use), paper
status, paper size, consumables status (e.g., ink, masters), print quantity, memory capacity used, and
data display volume, all viewable from a PC monitor.

Compatible with paper originals, with a full complement of handy features
for high-quality image reproduction
The RISO V8000 includes a scanner function, facilitating two-color printing of paper originals. The
backlight beneath the stage glass and alignment sheet allows checking of document alignment at a
glance, and print drums can be individually adjusted both horizontally and vertically for fine print
positioning adjustment. A function eliminates moiré (interference) patterns that are generated when
scanning shaded areas of documents or half-tone photographs. This is a new function that ensures
even better reproduction quality.

Complete with energy-saving mode
The RISO V8000 can be used immediately after being powered on. No energy-wasting warm-up
period is required. And unlike photocopiers, the RISO V8000 does not incorporate a heater, and thus
generates no waste heat. It also features an auto-shutoff function and sleep mode to automatically
switch off power if left unused for a preset length of time.
