Oki C3400n review: Oki C3400n

The Oki C3400n laser printer is networkable and fast with color prints, but its paper-handling options are limited, and like all lasers, its color prints are pricey and prone to errors.

Like most laser printers, the Oki C3400n is large. The gray-and-white unit stands 14.8 inches wide, 19 inches deep, and 11.4 inches tall, and it weighs a hefty 42.6 pounds. Hand wells on three sides make it easy to grip, but its bulky frame makes moving it a two-person job. The printer comes standard with a 200MHz PowerPC processor and 32MB of RAM, though you can upgrade to up to 288MB of RAM. Both Windows and Mac operating systems are supported, and the printer is Ethernet-ready, a boon for a multiuser environment. Duplexing (or double-sided printing), however, is a manual operation on this model, and Oki does not offer an optional duplexing unit for this printer.

The Good

Superspeedy color prints; excellent quality with black text; straight pass-through; network ready; expandable memory; 24/7 customer support.

The Bad

Paper capacity is not expandable; no duplexer; color prints are on the pricey side.

The Bottom Line

The Oki C3400n laser printer is networkable and fast with color prints, but its paper-handling options are limited, and like all lasers, its color prints are pricey and prone to errors.
Small-office users generally need a printer that is fast, networkable, cost efficient, and excellent with text prints. This usually means they are in the market for a laser printer. The Oki C3400n fits the bill, though it's not without its downsides. The $400 color laser printer won't break the bank, in terms of upfront cost and the cost of mono prints, but the cost of color prints will eventually add up. Also, the C3400n doesn't include a duplexer and its paper capacity is not expandable--both features that are common on laser printers. If you need those features, check out the , but keep in mind you'll get slower print speeds. In terms of speed and print quality, the Oki C3400n is a speed demon with color prints, but it lags behind the Lexmark C500n in black print speeds, though not by much. If you're a small-office user looking for a fast performer with good-quality prints, the Oki C3400n is a good choice.

The Oki C3400n suffers from limited paper-handling options. The pull-out paper cassette can hold only 250 sheets, and Oki doesn't offer an additional tray; if you print a lot, you'll find yourself constantly refilling the cassette. The cassette can accommodate paper up to legal length, but you can print sheets up to 35.4 inches long--for banner-style prints--using the single-sheet manual feed slot (hidden behind a fold-out panel). The top-mounted output tray is the default output area, but a door in the back of the printer allows for straight pass-through--convenient for heavier paper that can get stuck when bending through the roller mechanism.

The top of the printer opens to reveal four toner cartridges set in a straight-pass arrangement. Each can be pulled out and replaced individually. The standard black toner cartridge (1,500 sheets) costs about $40.75, while the high-capacity black cartridge (2,500 sheets) costs about $60. The standard-yield color toner cartridges (1,000 sheets) cost about $48.50, while the high-yield cartridges (2,000 sheets) cost about $87 each. Oki estimates printing costs to be about 2.7 cents per page for mono prints and about 16.7 cents per page for color prints, based on using high-capacity toner cartridges. The black print cost is about average for a printer in this price range, but the color cost is a bit high.

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.
