ComColor® FW5231

Compact and Feature-Rich to Improve Efficiency

Inkjet printers require no heat when printing unlike laser printers. The ComColor FW5231 boasts ultra-fast print speed combined with a fast first print time to streamline printing, helping make busy work environments more efficient. Its ultimately low power consumption prevents paper from curling to reduce paper jams. And because output requires no cooling, pages can be sent immediately after printing to any of your optional finishers, vastly reducing production times.

High Productivity

With a print speed of 120 ppm, duplex scanning and a rich feature set, the ComColor FW5231 brings a new level of productivity to any workplace. Affordable on-demand, full-color printing ensures smooth operation to increase your business’ efficiency.

Simple Operation

The easy to use and intuitive user interface of ComColor FW5231 makes anyone a master of efficiency. An easy-to-view touch panel with instantly recognizable color icons makes printer operation simple for anyone. The tilt panel ensures excellent viewing at any angle up to 90 degrees, expanding installation flexibility. Scan preview windows show scanned images before saving data, ensuring fewer scan failures. For added convenience when printing and copying, frequently used functions can be saved as Favorites.

Compact Design

The compact print head and tray-free design make for a device 33% slimmer than previous models, allowing installation of ComColor FW5231 almost anywhere. The modest footprint of an FW is the ideal choice when space is at a premium.

Expanded Usability

The optional PS kit supports a variety of operating systems, and PDF files can be printed directly from USB flash drives, while RISO Print-S application allows printing from smart devices. ComColor FW5231 offers reliable support for any work environment.

Energy-Saving Functions

New features allow you to automatically power the machine on and off at specified times. Up to 10 sets of combinations of start or end time and day of the week can be registered. Users can also set when the printer enters Sleep Mode after the last print job, further decreasing power consumption. This mode keeps power consumption to a miniscule 4W, further enhancing savings on electricity bills. All ComColor machines are ENERGY STAR® certified, and boast many other energy-efficient innovations.

Low-Cost Color Printing

ComColor Standard - RISO's original color profile - accurately controls the amount of ink ejected from the print head depending on document type and media. This maintains image quality and optimizes ink usage, ultimately lowering operating costs. Short print runs can now be performed inexpensively and efficiently in-house. FW5231 also supports variable-data printing, eliminating the need for pre-printed stock.

FORCEJET™ Technology

Stable paper feeding ensures the reliable performance necessary for high-speed printing. Paper-feed speed is intelligently controlled, according to how much ink is emitted from the print head. Multiple sensors help ensure high levels of reliability. Instant-drying ink complements the high-speed, duplex printing capability. This specially developed, oil-based ink is also fade-resistant and water-resistant, and minimizes paper curling.

Useful Scanner Functions

The optional Scanner HS7000 can save scanned data over the network to a PC, as an attachment to e-mail, or onto a hard disk of a networked RISO machine. Multi-page documents can be saved in PDF format as either separate files or combined into one file. Documents can be saved as PDF, TIFF, JPEG and PDF/A (suitable for long-term storage) formats.

Easy Installation

The FW series runs on a standard 110V outlet, making it usable just about anywhere. The FW5231 delivers high performance in a fraction of the space required by other printers.
