中文Speed is seductive in printing. We all say we care about quality and colour and sustainability, and we do — but deep down, every print manager wants the pile of paper to disappear faster. Riso knows this, and its new ComColor GN Series is basically a love letter to impatience.
The headline number is almost absurd: the top model, the GN9830, pushes out 180 A4 pages per minute. The GN7630 isn’t far behind at 160ppm. These are cut-sheet inkjet printers, the kind of workhorse you find in high-volume transactional, direct-mail, and in-plant environments where the clock is always ticking. Riso is calling the series “world-leading,” and at those speeds, it is hard to argue.
But raw speed is easy to brag about and easy to fake in a brochure. What makes the GN Series interesting is everything wrapped around that speed.
First, the ink. Riso uses oil-based pigment ink in a heatless printing process. No fuser, no oven, no energy-hungry heating element. That matters more than it sounds. Heatless means lower energy use, which means lower running costs and a smaller carbon footprint — and in 2026, when every procurement officer is asked about sustainability, that is a selling point, not a footnote. Anthony Larner, product manager at Riso UK, framed it plainly: the GN Series is “a massive leap forward from the GL Series, giving high-volume print operators unmatchable productivity, reduced energy usage and superior output quality.”
Second, the brains. Both models carry a new AI Predictive Diagnostic System. It monitors paper dust levels, automatically optimises sensor sensitivity, and adjusts the tray position to stop double-feeding before it happens. Anyone who has ever watched a high-speed machine jam and then watched the whole floor grind to a halt will appreciate that this is not a gimmick. It is the difference between a printer that needs a babysitter and one that mostly looks after itself.
Third, the small efficiencies that compound. Riso says routine cleaning cycles are 29% shorter, and the instant-on sleep recovery is 13 seconds. Thirteen seconds does not sound like much until you multiply it across dozens of wake-ups a day. Similarly, the series delivers up to 10,000 A4 sheets per hour and holds a print resolution of up to 600dpi on paper up to A3 (or US ledger size). Newly formulated oil-based inks widen the colour gamut, and aerodynamic airflow optimisation under the printhead keeps dot placement precise and text sharp.
There is also a nod to the modern hybrid office: the new HS10000 dual scanner handles duplex scanning at up to 200 images per minute and pushes straight to the cloud. So the machine is not just a printer; it is a document hub.
The series got a quiet preview at the Sign Print & Pack Denmark exhibition back in September, and it officially lands in the UK market on 2 November, available through Riso UK or its authorised partners. That timing puts it squarely in front of budget-season buyers who are planning 2027 capital expenditure.
Here is why this should be on your radar even if you never buy a Riso. The industry narrative for years has been “inkjet is the future of production print,” and machines like this are why that is no longer a future tense. When a cut-sheet device can hit 180ppm, stay heatless, self-diagnose, and still look good doing it, the old divide between “fast but ugly” and “pretty but slow” starts to collapse.
For in-plant print rooms, fulfilment houses, and anyone shipping mountains of statements, letters, or mailers, the math is simple: faster throughput plus lower energy plus fewer jams equals more jobs out the door with the same or fewer people. In a labour-tight market, that is not a nice-to-have. It is the whole game.
Riso has been in inkjet for two decades — 2025 marked its 20th year since entering the market. The GN Series reads like a company that has spent those years learning exactly where the friction lives in high-volume print, and then quietly removing it. Your copier, meanwhile, is still warming up.
