Summary: Fast delivery, easy set-up, works great. I ordered this to replace an older model Oki - it was far less expensive to buy this new one than to replace all the drum cartridges, transfer belt, etc. on the old one. This new printer is smaller, faster and much quieter. So far I'm very pleased with this purchase.
Summary: This is a great printer for a small office. It seems to be a much more solid printer than the HP Laserjet it replaced. It is definitely more dependable. It is very similar to the Oki multifunction printers. It appears to be the same printer without the top scanner part. We have been using the Oki multifunctions for a couple years and are very satisfied with them also. I give it 4 stars rather than 5 because: It is not AirPrint compatible. (Oki has other models that are.
Summary: Our 2nd Okidata printer. The first one lasted almost 12 full years without a glitch, so we thought we'd give it a try again. Called directly to Okidata and asked for a comparative model. The Okidata representative provided this model and SUGGESTED purchasing it from Amazon.com. I double checked that with my son, a long time computer/electronics tech. He agreed, stating that Amazon is "THE BEST" about returns, if anything is wrong with the item.
Summary: I ordered the Okidata C531dn color printer after my C5500 died. It had been a great workhorse color printer for 7 1/2 years. Unfortunately, the parts became too expensive to replace, so I looked for another color printer. I initially bought a Brother multifunction color printer but the pages curled terribly and the color was just okay. So I looked at the Okidata lineup and chose the C531dn. The printer had great reviews, so I hoped it would work as well as my C5500 had.
Summary: I had an Oki Data C330dn printer for a long time. It got damaged and I decided to replace it with the C531dn, which is very similar but can print faster. I ended up buying it not from Amazon but directly from Oki Data, because at the time I couldn't find the 531dn offered on Amazon. It is a really wonderful printer, easily the best page printer I have ever used.
