Oki C5510n review: Oki C5510n

Speed
The Okidata Oki C5510n has the fastest multifunction scanner we've seen to date in CNET Labs. This machine scanned our color-graphics test document in less than six seconds, which translates to 10.6 pages per minute (ppm). Competitors clocked an average of 2.5ppm--more than four times slower. The C5510n's grayscale test scans were even zippier.

The C5510n was also no slouch as a printer, rolling out black text at 13.5ppm--better than the Canon ImageClass MF8170c's 7.74ppm. This Oki printed color graphics at 8.83ppm, even faster than color text. Black graphics printed at an impressive 13.43ppm, again outstripping competitors.

Quality
The Okidata Oki C5510n multifunction turned in a mixed quality performance in CNET Labs' printing tests. Black-text prints were terrific and sharp even at small sizes, and grayscale graphics displayed nearly perfect gradients and good detail. Color prints were another story, with oversaturated and mismatched colors. In some cases, this printer failed to color inside the lines, and it spliced red into orange and yellow. When we investigated further by printing images of Impressionist paintings from the Web, the prints looked vivid and lacked obvious errors. Our color and grayscale test scans were sharp and clear, with nicely balanced contrast. Colors were a bit dull but easy to perk up with the bundled software.

The guides and the manual included with the Okidata Oki C5510n multifunction are clear, but we'd like to see just one comprehensive manual instead of two CDs and a pair of printed guides. The support area of the Oki Web site offers helpful information about consumables and accessories, as well as drivers, manuals, specs, and a knowledge base. For on-the-spot assistance, you can stick the included Handy Reference guide onto the printer's cover.

This multifunction is covered by a one-year limited warranty with overnight exchange for defective units and a five-year limited warranty for the LED printheads. Toll-free tech support is available 24/7.
