The FORCEJET Advantage

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 an amazingly fast print speed of 165 pages per minute for A4 longedge feed in simplex.

The FORCEJET Advantage

Stabilized Paper Feed

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.

Stabilized Paper Feed

High-speed Printing Ink

Special quick-drying, oil-based pigment ink developed exclusively for the ComColor GL9730 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.

High-speed Printing Ink

Amazingly Fast Speeds at 165 ppm

Higher Productivity, Higher Quality Regardless of the number and types of images or volume of text, full-color images remain true to the original. For text-intensive documents, words remain crisp and easy to read.

Super High-speed Printing Single-pass full-color printing of up to 165 A4 long-edge feed color pages per minute with fast-drying oil-based pigment ink is possible through a unique print engine configured with static inline inkjet heads arranged in parallel. Transactional prints, trans promotional materials, invoices, and other routine business documents are also fast.
Controlled Quality Output High-precision paper-feed control enables printing at the same speed for both simplex and duplex documents to boost productivity. The responsive first print time of only five seconds means less waiting for high-volume print jobs.

Faster Scanning and Copying (Optional) A one-pass duplex scanner improves scanning or copying, boasting a simplex/duplex scanning speed of 100 pages per minute and copying speed of 70 pages per minute. User name is automatically added to the document name, and each page of scanned data can be saved as individual PDFs. Features like ZIP compression and saving in PDF/A format are also available.

Built-in Quality and Flexibility

Built-in Quality and Flexibility and Enhanced Color Reproduction Features

Taking Quality to a Higher Level
The ComColor GL9730 is engineered with features that ensure stable output quality for consistent printing results at high speed, including a Piezo system that regulates ink amount. Black image quality has been improved by installing a newly-developed print head and black ink. Additional inks enrich the look of images and enhance overall color quality.

This unique RISO technology and approach to the printing process brings the added benefits of a low total cost of ownership when compared with toner technology, and greater control over cost management. It also enables practical migration away from simply highlight color or mono production to a cut sheet white paper solution. This provides genuine added value, as it eliminates the need to hold large volumes of pre-printed stock and opens up possibilities for a leap forward in color printing.

Consistent Output Quality
The ComColor GL series offers higher image quality and consistent printing results through RISO inkjet technology that features a Piezo system, which ensures stable output by controlling and regulating the amount of ink deposited on the paper.

Best Black Density
A newly-developed 600 dpi print head for black with special black ink supported by gray as a fifth ink delivers top quality, 10% higher black density than ever. 

Enriched Color Images
Newly-developed magenta ink significantly improves full-color image quality by expanding the color gamut.
