About the OKI Data 421

The OKI Data Microline 421 Forms Wide Carriage Impact Printer is engineered for dedicated forms printing in the most demanding point-of-sale, automa-tion and utility environments, ML421 printer is right at home in applications such as retail sales counters, medical facilities, automotive rental and repair shops, airline counters, financial departments and manufacturing sites. It's print speed and versatile paper handling makes it ideal for the office, too.

The ML421 has a zero-tear feature that accurately positions continuous forms for a clean tear at the perforation, which eliminates wasted stock. You also get perfect results with single sheets, index stock, labels and envelopes, too. All with-out jams or smears. The OKI ML421 delivers the kind of productivity usually reserved for printers many times the price-starting with a super-fast print speed of 570 characters-per-second (in SuperSpeed Draft mode). Then there's the rugged printhead-with its 200-million character life, powerful samarium cobalt magnets and stored-energy pins - delivering precise, sharp characters all the way through to the last page of a 6-part form.

And the patented OKI closed-loop feedback system that assures character placement accuracy. The performance-optimized power supply of the ML421 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 ML421 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.
