RISO's high-speed inkjet technology, FORCEJET, consists of wide, color, in-line inkjet
print heads arranged in parallel for single-pass printing of black, cyan, magenta, yellow
and gray on A3/Ledger short-edge feed paper.

Fast printing functionality combined with a rapid and stable paper supply results in a
print speed of 160 pages per minute for A4 long-edge feed, in simplex literally the fastest*1 in the world.

*A4 long-edge feed, simplex, continuous printing in standard density setting,
based on office color printers using cut sheet commercially available as of
September 2016 (Source: RISO data).

A straight-path feeding system feeds paper horizontally to enable high-speed printing
with minimal print offset.

FORCEJET technology ensures optimal paper feed speed that is matched to the
amount of ink being sprayed from the ink heads.


Special quick-drying, oil-based pigment ink developed exclusively for the ComColor GD
series prevents reverse-side staining of printed paper as well as cockling, to allow for
unprecedented high-speed duplex inkjet printing.

The ink is also resistant to degradation from light and water.
