Oki C3400n review: Oki C3400n

In terms of performance, the Oki C3400n impressed us with its fast print speeds. When printing black graphics and black text, it printed just slightly slower than the competition, including the Lexmark C500n and the Samsung CLP-510N: 16.01ppm and 15.55ppm, respectively. It knocked the competition out of the park, though, with its zippy color graphics and color text speeds: 11.92ppm and 8.38ppm, respectively. The only printer we've tested recently that beat these numbers was the C3400n's big (and more expensive) brother, the C5500n.

Turning from print speed to quality, the Oki C3400n was a middle-of-the-pack performer. It excelled where we expect a laser printer to excel--black text--and faltered where we expected--color graphics. Black text was smooth and uniform, with no noticeable errors. Black graphics showed nice detail and a smooth grayscale progression, but photographic elements showed hash marks. Some of the color text also revealed dots and hash marks, and color graphics fared worst of all. The color gradients showed banding (as did the grayscale), and flesh tones were overly red, while grays were overly blue.
