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 timehttp://www.amazon.com/gp/product/B003TTELG8/ref=cm_cr_ryp_prd_ttl_sol_5 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: 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: My old OKI color laser was showing its age, so I decided to upgrade after about 7 years of reliable output. Two primary reasons I chose this one for replacement are outstanding customer service by the manufacturer and the ability to print on card stock. The range has been expanded for thickness of acceptable card stock and the print quality has gone from good to really impressive for a color laser printer. Duplex printing [included] came as a bonus.
Summary: The OKI 530dn is an amazing color laser. Coming from a HP printer I am thrilled. First, after the first set of "gimped" toner, I get about a 40% savings in toner cost. The second is speed, this printer is literally 8X faster than the HP per page in color. The third is quality, although a hair less sharp than the HP the quality is awesome (you have to look under a loop to see the difference though) the colors come through with greater depth than the HPs.
Summary: After the initial shock of having just received the new printer that was defective ( probably in shipping. Don't know why they didn't ship from Ontario instead of BC ) was glad that Okidata stood behind their product so well that I had a replacement 2 days later without having to pay for shipping the defective one back! ( oki shipped the prepaid return label with the new printer ) Very happy with how well this printer works!
Pros: Very fast printing in both color and b/w, Does a very good job of printing photographs!, Very easy to setup, Nice web based interface when networked so you can keep track of what the cartridge levels are and how many prints you have done, Easy way to change settings for it too, Network setup was a snap!
Cons: Original toner cartridges are only partial not full, Original order printer was shipped from BC instead of Ontario. Printer was defective! Called Okidata and had replacement printer 2 days later with them paying for return of defective one in advance!
