C9DP+ Envelope Print Systems

Across the C9DP+ Family of Envelope Printing Systems, you can count on vibrant, press-like color saturation, reliable speeds, and consistent results, thanks to:

  • 1200 x 1200 dpi LED printheads
  • 2 GB memory, 1 Gigabit network
  • Flexible media handling
    • Envelopes as small as 2.5” x 4.5” and as large as 13” x 15”
    • Heavy stocks up to 360 gsm
  • Straight-through paper pass with automatic duplex printing
  • PC and Mac® OS Postscript® print drivers with trapping
  • Variable Data Printing
  • Small footprint

With its unique ability to print brilliant colors on dark colored media using white toner under CMYK, the C942DP+ is the ideal solution for print shops aiming to satisfy their most creative customers. White is in the fifth toner station, meaning this groundbreaking Color-on-Color output is printed in a single pass. This used to require large, expensive machinery but now can all be done in-house within a small footprint.

The versatile member of the family, the C941DP+ offers both white and clear toners for white-on-color graphic output, and other specialty projects. Clear toner enables users to enhance designs and graphics with custom watermarks and embellishments.

For top-of-the-line output in traditional CMYK applications, the C931 is the affordable option. If your customers aren’t demanding colored envelopes and stocks, you can still offer them world-class four-color output on white media.

Press quality without the mess. Fast digital turnaround. No setup costs.
Customer requests for short-run envelope production (runs of 5,000 or less) used to be a headache for print shops large and small. It’s not economical for traditional offset printers and too much trouble even for small digital print shops. The C9DP+ Envelope Print Systems from OKI® opens the doors to new business opportunities with a range of print engines and options that can expand the services you offer.

Faster and Easier than a Press
Extend your in-house color printing capabilities from the expected to the extraordinary. Each C9DP+ model enables you to print short runs in less time than it takes to produce printing plates and ink up a press. A duty cycle rated at up to 300,000 pages per month means the system is rugged enough for longer runs, too. Print up to 500 Com-10 envelopes in less than 12 minutes¹ with output that rivals traditional offset printing presses.

The C9DP+ Envelope Print System is easy to set up and attach to any of the C9DP+ family of printers (C931, C941, and C942).  The DP+ feeder has been designed to achieve new levels of Ease of Use and reliability.  Simplified adjustments make it easy to switch out media, set up a new job, and produce repeatable results. Guess work has been eliminated. Envelopes feed consistently with little, to no interventions – including Window envelopes!
