Lexmark C543dn

The boxy printer's configuration has one nice bonus, standard automatic duplexing. Everything else is basic: a 250-sheet main input tray with a manual-feed slot, and a 100-sheet top output area. If you need more paper capacity, a 550-sheet second drawer costs $199. That seems pricey, but it includes a 100-sheet multipurpose feeder. The control panel is minimal but usable, with a two-line monochrome LCD and self-explanatory navigation buttons.

Maintaining the printer is fairly simple. The new engine features keyed toner supplies nestled behind a door on the side of the printer--which makes for easier access than having to open up the printer's guts. While it's initially unclear whether you should pull or push on the cartridge release levers, instructions inside the compartment door eased my confusion. Trickier, but rarer, tasks include replacing the toner reservoir and the print heads.

Low-cost lasers tend to have high-cost consumables. The C543dn offers some initial relief by bundling high-yield, returnable versions of its toner supplies: a 2500-page black (K), and 2000-page cyan (C), magenta (M), and yellow (Y). At the time of our review, replacing these supplies cost $70 for black and $83 for each color. Compared with other high-yield supplies we've priced, the costs per page of 2.8 cents for a plain-text page and 15 cents for a four-color page are on the pricey side of acceptable. But they're still better than the standard-size, 1000-page supplies: black costs $45 or 5 cents per page, while each color costs $59 or 5.9 cents per page. A four-color page would cost a whopping 22 cents.

The C543dn must live down Lexmark's worse-than-average rating for reliability in PC World's Service and Reliability Survey. Let's hope it can overcome its past, because it would make a decent, low-cost printer for small offices with light graphics needs.
