Hands-On Review and Videos: OKI’s C941dn Multimedia Color Printer – Pushing the Envelope of Image Quality with White and Clear Toner

  • Clear toner makes prints more durable and appear more professional and vibrant – similar to results produced when printing on photo paper. Clear toner can be selectively applied and is always printed on top of the CYMK toners and white toner.
  • White toner can also by printed under color toners, which makes colors pop, especially when printing on transparent films.
  • White text and graphics can be used to print on dark-colored media, as opposed to printing a dark background on white or light-colored media –
    • This saves significant amounts of toner versus printing a color background on white- or light-colored media.
    • Since colored substrates have edge-to-edge color, there’s no need to trim the white border around prints on white-or light-colored media.
    • There is faster job turnaround and less waste because no trimming is required ,and post-processing procedures such as folding and insertion utilize standard media sizes.
    • Colored stock has nearly zero color drift, and doesn’t tax the printer as much as printing a heavy background color on white- or light-colored media.

Changing Spot-Color Units

The OKI C941dn’s clear spot-color toner cartridge with developing unit below.

As noted, the C941dn has five developing modules that hold cyan, magenta, yellow, black, and either white or clear developing units. As seen in the following video, the process of changing them is easy enough, but should be performed by an individual with proven technical skills:

    who need quality!
    I’m stuck with a lease on a C941e. Yes, the quality is amazing but who needs quality if u are loosing money on every print. First to fill up all ink cartridges is about $800, (the machine only takes originals) and it yield you maybe maybe 2000 12×18’s. how much does Oki think we can sell these print for? now don’t start talking to me about the drums every drum replacement is about $600 which adds up to $2400 its just crazy and it doesn’t make any sense whatsoever. DO NOT BUY THIS MACHINE. you will loose your pants. I’m now stuck if I don’t use it I’m anyway have to pay the payments not to ruin my credit. so I’m lost either way. again do not buy it!!!!!!!!!!!!!!!!!!!!!

      Good information in general folks. Just because a printer is affordable to buy does not mean it is affordable to own. If you research the content on this Web site, we have been railing about this for too long to mention. It also shows that with this particular machine and its unique capabilities, you surely need to price your prints accordingly.

      It appears that the only solution left for Joshua is to forget about the white and clear toners and use his C941e as a typical printer in order to minimize his costs. That also means producing prints in black-only and/or draft modes for archival and internal purposes. He may even want to get rid of other printers that are being used for this purpose in order to shift print volumes and maximize his investment with this printer. Finally, Joshua may want to approach his dealer or a third-party MPS provider and negotiate a fixed and more affordable Cost Per Page.

    I had bought a OKI 340ex and stuck with it too as the consumables are so god damn expensive. The dealer was crazy to send his person for any small repair or problems with $150.00 minimum and the whole deal was crazy. I stopped using it, and it is lying as junk in my place. So anyone trying to buy OKI please refrain, if you are from the printing industry.
    The company themselves are least bothered, about the clients problems. You would be better of with Konica, Cannon or even Xerox.
    What Joshua has mentioned is damn right. The other parts are so expensive, in comparison.
