Oki C3400n review

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 -- colour graphics. Black text was smooth and uniform, with no noticeable errors. Black graphics showed nice detail and a smooth greyscale progression, but photographic elements showed hash marks. Some of the colour text also revealed dots and hash marks, and colour graphics fared worst of all. The colour gradients showed banding (as did the greyscale), and flesh tones were overly red, while greys were overly blue.
