Okidata ML521

 
 
 
 




There’s nothing like it in its class. The MICROLINE® 520/521 is measurably faster: it prints faster in any mode, and feeds paper faster, too. And its printhead is designed to last twice as long as those of competitive dot matrix printers. It also has something you won’t get with conventional 9-pin printers: patented OKISMART Paper HandlingTM for hasslefree switching between different paper types. No more guesswork. No more searching for the owner’s manual. No more paper jams or uneven print quality. Instead, the ML520/521 “reads and learns,” automatically adjusting to the paper you feed it. You get perfect output on single sheets, card stock, multi-part forms (up to six parts!) and labels. What’s more, envelopes print out flawlessly, with no jams or smears

Individual pins in the printhead also adjust to the changes in paper, so uneven printing, smears and light spots are things of the past. The printhead lasts longer, and the printer uses less power and works more efficiently. The ML520/521 can also increase your productivity: paper loading is easier than ever, and its jam-free paper path ensures uninterrupted throughput during long print runs. It can save you money in the long run, as well: the zero tear function of the optional Bottom Push Tractor lets you print on “difficult” media without wasting any forms. You get handsome output and exceptionally fast throughput every time you print with the ML520/521.

When it comes to sheer print speed, the ML520/521 turns out a blazing 435 characters per second (cps) in high speed draft print mode, 325 cps in utility mode, and 80 cps in near-letter quality mode. The ML520/521 has 8 resident bar code fonts, including USPScertified PostNet,TM for envelopes and labels. Plus, to get the most out of your software without extra cost, select from Epson,® IBM® and MICROLINE® emulations, all of which are resident standard. The ML520/521 is so reliable, it comes with a 1-year warranty on parts, labor and printhead. In addition, the ML520/521 printhead has a life expectancy of over 200 million characters, so you know it can do the job when you need it. The ML520/521 has several OKI-engineered accessories to help you make the most of your work day — including a Bottom Feed Push Tractor kit for thick forms; a Pull Tractor for multi-part forms, card stock and labels; a serial interface that lets you connect easily to a variety of systems and increase the productivity of your work environment; a 4-million character long-life ribbon; and a Cut Sheet Feeder that gives you more time for other work during long, unsupervised print runs. For reliability you can count on, it’s the ML520/521.
