Digital Color printers from OKI deliver more than brilliant output at best-in-class speeds – The C331dn and C531dn also offer a long list of features that can improve your image, profitability and peace of mind:
Control the quality of your output
Color Swatch Select the color swatches that match your target and simply use their RGB or CMYK values while creating your document to ensure matching colors.
Customize a swatch by setting the Hue, Saturation and Lightness to target your custom color.
Color Correct Makes it easy to adjust colors commonly found in applications like Microsoft® Word, Excel® and PowerPoint®. It also lets you adjust the overall color of a print by controlling the lightness, darkness and contrast of images, and the intensity and lightness of the colors.
Control your printing costs
Print Job Accounting Software Enables tracking of color and mono printing costs, easy monitoring of printing activity, and greater control of printer usage. It generates reports for administrative, bill-back or cost-accounting purposes. User permissions can be assigned and are stored on the printer, so the system is totally secure.
An important feature of Print Job Accounting is the use of color printing restrictions. This lets you control and monitor color usage by defining who can print and what gets printed, making color printing costeffective. Decide who and what can print in color, in black & white or not at all. Access levels can be assigned by user name, application, file name and web sites. Once policies are configured, the printer determines how-or if-incoming jobs will print. All policies are password-protected for added security. Control your effect on the planet’s health The C331dn and C531dn offer a number of environmentally friendly features, including:
Duplex (2-sided) printing It’s standard on the C331dn and C351dn.
Use both sides of a sheet rather than two sheets.
Saves paper-and is even more energy-efficient.
Automatic ECO Mode These printers optimize the print time for small jobs, using less energy. Same terrific output, faster throughput, lower power consumption. Everybody wins.
Deep Sleep Mode When left on for an extended period, the C331dn and C531dn slip into this mode, which uses less than 1.5 watts of power. One-piece image drum This long-lasting, userreplaceable consumable remains friendly to your budget while lowering the number of items to dispose of and store.
Energy Star® compliance With their lower power consumption-especially in Deep Sleep Mode – and standard duplexing, these printers meet the government’s standards for energy efficiency.
