Robust and fast—with a remarkably small footprint. With C831 Digital Color Printers from OKI® you get the most advanced color technology in the marketplace, for printing on letter/A4, tabloid/ A3, even banner-size sheets up to 52" (1.3 m). C831 Series printers deliver 35 clear, sharp letter/ A4 pages—or 20 tabloid/A3 pages—per minute in color or black & white, with the first page printing in as little as 9.5 seconds.3 At those speeds, you’ll have more time to spend on what’s really important: your business.
Breathtaking document output. HD Color Printing technology delivers stunning results from this compact, easy-to-use printer. The OKI process combines high-definition LED printheads that put color on paper with exacting accuracy; microfine high-definition toner to ensure that graphics are breathtaking, and text is sharp and crisp—even on ordinary office paper; a straight-through flat paper path that handles a variety of media, from heavy card stock to polyester film to long banners; and an advanced control system that constantly checks alignment, registration and color balance.
Do it all for less. Now you no longer have to depend on outside services for printing your high-quality color documents. Print whatever your business requires to meet your communications needs: manuals, catalogs, banners, proposals, business cards, photos, brochures, floor plans, and all types of presentation materials. Print everything on demand (when you need it), in-house and at an affordable cost.
Unmatched warranty support. OKI is so confident in the reliability of our C831 Series Digital Color printers that we provide a 1-year limited on-site warranty for parts and labor4 , and back our LED printheads for an industry-leading 5 years. Optional warranty extensions are also available.4
Secure your document output – C831 Series printers include Secure Print features5 that encrypt job data, store it on the optional SD memory card, and completely purge and overwrite it when the job is printed. With PIN-number protection, “owners” of sensitive documents can use the C831 printer’s numeric keypad to quickly and easily release their confidential output.
Monitor and control color printing – OKI Print Job Accounting software with the C831 Series allows you to restrict printer access to individuals or groups, and to manage printing within defined cost limits. It also provides you the ability to report on usage across the network, capturing information on volume, paper size, media type and consumables usage.
Its color access restrictions make color printing more cost-effective, allowing administrators to control printer usage by determining who and what can print in color, in black & white or not at all on your C831 printer. It also enables printer monitoring, letting you create job logs to analyze how a device is being used—by user name, applications used, and number of color or black & white pages printed.
The data can help you determine the effectiveness of your existing policies or to develop new ones.
Improve efficiency. Reduce environmental impact – C831 printers offer a range of features to reduce energy consumption, save you money and improve your carbon footprint.
These include a design that lowers power consumption, starting with LED technology that inherently consumes less energy:
• Deep sleep mode – Reduces power consumption to less than 1W
• Auto-off mode – Automatically powers off from Deep sleep mode, reducing energy consumption to 0.15W when not in use
• Duplex printing (optional on C831n) - Reduces paper usage by enabling the user to print on both sides of the sheet
• Toner save function – Reduces the amount of toner used when printing draft or internal documents

Printer: 1-Year limited On-site
Digital LED Printheads: 5-Year limited warranty
OKI Printing Solutions has pioneered the development and use of LED technology in printing for over 20 years. LED or Light Emitting Diode/Device is the type of light source used in the electrophotographic printing method for most of our printers.LED printheads use an array containing multiple LEDs and the LEDs individually turn on and off according to print signals.
Conventional LEDs have a two-terminal structure comprised of an anode and a cathode. In a technology made possible by Epi Film Bonding, the new LED array features a three-terminal structure comprised of an anode, cathode, and gate, adding switching capabilities to the conventional LED function of emitting light. The new LEDs reduce the number of wires required in the chip and reduce chip width by 22%. They also make it possible to deploy a single power line on the substrate on which LEDs are mounted, halving the number of substrates used.
OKI Printing Solutions was the world's first company to achieve high-volume production of LED printheads based on this new technology. All future LED products will incorporate this new LED printhead.
LED Printhead Advantages
- Smaller dot sizes create highly accurate output
- Multi-level shading provides superior print quality and clarity
- LEDs have no moving parts and are ultra reliable
- LED is smaller and more compact, using fewer material resources and energy
LED vs. Laser
Laser systems rely on elaborate combinations of rotating mirrors and lenses that must remain in alignment through use. The laser scans from one end of a line to another, then zig-zags down to the next line.
LED technology uses a Light Emitting Diode printhead as a light source within the imaging device. Unlike laser systems, the LED printhead is solid-state and has no moving parts. The LED bar pulse-flashes across the entire page width and creates the image on the print drum as it moves down.
OKI also has a straight-line paper path (Single Pass Color) that's less susceptible to jams when feeding heavy stock, envelopes or labels.
LED technology is the future. We're so sure of this that we guarantee the printhead of every OKI page printer for five full years — by far the longest warranty in the industry!
LED Dot-Size Precision
With 1200 dpi (dots per inch) print resolution, a printer should place 1200 dots/spots, precisely printed at 25 micrometers apart (on center). However, while a 1200 dpi LED printer can produce a 25 micrometer dot/spot, a 1200 dpi laser printer can only produce a 65 micrometer dot/spot. This translates to greater print quality when using LED technology. See the animation at right for a quick demonstration of this comparison.
Multi-level vs. Bi-level Printing
Traditional laser printers apply dots using two levels of intensity: 100% black or 100% white. Dots are grouped together (creating halftone cells) to simulate levels of grey. This is referred to as bi-level printing.
By contrast, our multi-level LED printing technology can produce different levels of intensity. This produces up to 16 shades or tones in the range between black and white. This is similar to the effect you get when replacing a standard light switch with a dimmer switch.
Multi-level Technology delivers more shades of grey or color within the same size halftone cell. This results in a higher level of detail and greater color depth, another great feature from OKI Printing Solutions.
Declared yield in accordance with ISO 19798. All models ship with 2,500-page "starter" toner cartridges.
- 2 Requires optional SD Memory Card.
- 3 Published performance results based on laboratory testing. Individual results may vary.
- 4 Available in the U.S. and Canada only.
