Summary: I had an Okidata C6000DN for many, many years that gave me excellent service. Some of the things I use & want in a printer: 1. Reliable duplex operation 2. Ability to feed envelopes in a stack, not one at a time B003TTELG8 3. Ability to print banner-sized paper (I have some 8.5" x 36" paper, longer sheets are available) Okidata is the only one out there I know of that does the banner-sized paper.
Summary: This printer got stuff hot. I had the Oki Data C5500N for almost 8 years before the image drums needed to be replaced. All four heads and toners were so expensive, I thought I would upgrade since this model's toner was cheaper. A buddy of mine ordered the C330DN and had good luck with it so I took a chance on this one. This printer gets my paper hot enough to curl and makes my envelopes almost seal. This is the same materials I used in the last laser with no problems.
Summary: This printer is excellent for letters and presentation documents but is not very good for printing photo or pictures. The colors are vivid . The demo from the printer is excellent. Printing a photograph the colors are over saturated and the photo is too dark and the colors are not all the same as the original. Using the printer utilities from the online web site do not fix the problem.
Summary: It works will and does what you expect a Okidata printer to do. Did not include a cord to connect printer to computer though. Had to go to a office supply store to get the right cable. Would have been nice to know that when I purchased it. That is the reason for the lower rating.
Summary: This device worked very well for several months. One day it stopped working so we called OKI. The warranty should have had the entire unit replaced but did not. The customer service reps just try to sell rollers, drums, fusers and toner one item at a time. This machine has not functioned for nearly 2 months and is still inoperative. In December we can use the Square Trade Warranty to replace this lemon unit.
Summary: Print quality has been very good. However, we bought two of these, and have had nothing but problems and they have been money pits for two years. Replaceable parts going bad at half their rated lifespan, transfer belts failing and image drums wearing out quickly (and you have to replace the tray of 4, when only the black drum wears out first), high voltage power supply going out, super expensive toner that doesn't last, on and on.
Summary: I owned an Okidata printer before, so I thought I would try this one. It's a piece of junk. I keep getting "service error". When I called tech support they said turn it off and back on. That worked for a couple of hours. Cartridges are expensive and don't last long at all. This will be the last Oki product I ever buy.
Summary: I've had several printers from HP, Brother, Samsung, Xerox, etc. This OKI printer is fantastic. It prints on both sides and is quick to output full color. I didn't give it 5-stars because of the price and the price of toner. When I was about to purchase the printer, I watched the price for a few weeks because it would change almost everyday, which is really odd since the printer has been on the market for several years.
Summary: I needed a 4 color laser printer with postscript support, and this model is one of a few that met the criteria and did not cost an arm and a leg. It works for what I bought it for. The full duplex function works fine, too. The images from this printer are much, much nicer than the same images from my Dell 1320c, which has performed flawlessly but lacks postscript support. The next Dell model that supports postscript is almost 3x the cost of this OKI printer.
Summary: I'm using this printer in my lab for biochemical research. I once have used Brother's color printer (I don't recall the model No.), but I like color printing of this Oki's printer better. One disadvantage is that it is slow for printing the first page. Otherwise, I'm satisfied with the performance of the printer.
