OKI® MICROLINE® 420/421

9-Pin Impact Printers

Built to last, inside and out. Field-proven reliability is just one reason OKI® MICROLINE® impact printers are the most widely-used in North America.1

The performance-optimized power supply of the ML420/421 has been enlarged to easily handle harsh printing conditions—and its energy management capabilities match power expenditures to print-job size, maximizing the life of the 9-pin printhead and other components. A long-lasting rack-and-pinion drive system ensures print quality longer than belt or cable systems. And the ergonomically-designed, impact-resistant chassis protects the ML420/421 from damage, even in the toughest working environments.

Performance that’s user-friendly. Controls are conveniently placed on the front panel for fast access. The automatic loading of continuous and cut stock makes every print job easier, and the design of the internal sheet separator enables easy loading of tractor-fed paper into the rear push tractor.

OKI has a reputation for quality and reliability no competing printer can claim—and backs it with

3 years of warranty coverage 2 and a network of authorized OKI Dealer Service Centers and Service Depots.

The reliable, affordable ML420/421 can work wonders in virtually any forms-handling application.
