RISO HC5500

In-line System Delivers High Speed Output

Based on high-performance ink jet technology used in commercial applications, the HC5500 is equipped with "FORCEJET™" high speed print technology developed for office printers. The technology consists of four colour 316mm wide In-line ink jet heads arranged in parallel, capable of printing onto short-edge A3 width paper with a single pass.
Cyan, black, magenta and then yellow ink droplets are rapidly sprayed onto paper passing beneath the print heads. Combining high-speed printing functionality with a rapid and stable paper supply, the printer attains print speeds of 120ppm*, the fastest in the world.

*For A4 size, long-edge feed, simplex, continuous printing in standard mode. Based on office colour printers using cut sheet paper commercially available as of August 2007 (Source: RISO data).


World's Fastest at 120ppm

No other sheet-fed ink jet printer can print as fast as the HC5500 at 120 pages per minute in full colour, the HC5500's print speed can't be beat by any other ink jet printer.


Duplex Printing as Standard

Once the front side has been printed, the sheet of paper is automatically reversed using a switch-back method paper feed and stack-less paper throughput mechanism to alternately print the front and back in a highly efficient manner. This technology allows rapid duplex printing at 96 ppm (48 sheets)* to dramatically improve printing productivity.

* For A4 size, long-edge feed, printing in standard mode.

Straight Paper Path for Stable Feed

The printer uses a straight path feeding system to horizontally feed paper into the machine. This method allows high-speed printing with minimal print offset. The printer's "FORCEJET™" technology provides optimal control of the paper feed speed to match the amount of ink being sprayed from the ink heads. A sensor to detect double feeds also helps to minimize problems such as paper jams.


Large-Capacity Paper Feed Tray

By loading the same size paper into the upper/lower 2-level front and standard paper feed trays, over 2,500 sheets can be fed into the printer*. The front paper feed tray can also be refilled when the standard paper feed tray is in use, allowing a large volume of paper to be continuously fed without having to halt the print job. And of course different paper sizes can be set in the front and standard paper feed trays respectively.

* For 85g/m² paper.



A3 Full Size Printing Made Possible

The HC5500 printer can print paper sizes ranging up to 340mm x 550mm*1. The maximum print area exceeds A3 size at 314mm x 548mm*2.

*1 When a paper feed tray is used.
*2 Depending on the application being used, printing at this size may not be possible.


Print Onto Card Stock and Envelopes Too

The HC5500 printer offers a wide range of options with its ability to print on card stock used in postcards (up to 210g/m²) and commercially available envelopes*. The paper feed tray can be set at an incline (one level), allowing the envelopes to be smoothly fed during printing.

* The paper feed tray is used when printing envelopes. Only simplex printing is possible. It may not be possible to print some types of envelopes.
* Please contact a sales representative for further details.


Special Ink for High Speed Printing

An oil-based pigment ink was developed exclusively for the HC5500 printer. The ink's quick-drying characteristics prevents it from staining the back side of the printed paper, prevents the paper from rippling, and allows high speed duplex inkjet printing at speeds that would have been impossible in the past. Duplex printing reduces the volume of paper being used and can reduce office printing costs. The ink is also resistant to light radiation and water. It's the perfect quality ink for business applications that demand resistance to fading and moisture.*

* Differs depending on paper type and usage environment.


Optimal Control of Ink Amount
The "FORCEJET™" engine achieves extremely fine gradations by controlling the ink drop amount so that up to 8 gradations can be achieved in a single colour dot.


ComColor™ Standard: Reducing the Cost of Full Colour Printing
The amount of cyan, magenta, yellow and black ink used is controlled to take into account the original and paper type. The unique ComColor™ Standard colour profile allows output at an image quality appropriate to the image to reduce ink consumption.

High-Volume Ink Cartridges

Each high-volume colour ink cartridge holds 1,000ml. The printer's ink cartridges let you make over 50,000 copies* without replacing cartridges. The one-colour-per-cartridge system also lets you replace only the colour that has been used up, and helps to reduce consumable waste.

* A4 size single side, RISO colour standard original, continuous printing in standard mode.
