A good blend of performance, quality, reliability, and affordability, the ML421 9-pin Dot Matrix Printer lets you easily produce letter-quality type and high-resolution graphics for the office and the executive suite! It’s specially engineered for dedicated form printing in the most demanding point-of-sale, automation, and utility environments.
This high-performance device utilizes unequaled performance technology – like a three-piece top cover, an internal cooling fan, and additional feed rollers. It boasts exceptional paper-handling versatility and the unique OKI closed-loop feedback system, a fast print speed of up to 570 cps, and a 200-million character printhead life, ensuring fast, accurate, and reliable printing results every time. In addition, it’s extremely durable and user-friendly. Its small footprint makes it perfect for retail countertops.
Unequaled performance technology The ML421 sports an array of excellent features, giving it a strong edge over its predecessors as well as the competition. The three-piece top cover provides easy access and unsurpassed break resistance. An internal cooling fan provides continuous airflow for the printhead, maximizing throughput productivity for long, unattended print jobs. Additional feed rollers provide precise form handling and printed-character placement accuracy.
Value that goes the distance The ML421 provides a super-fast print speed of 570 characters-per-second (in SuperSpeed Draft mode). Its rugged printhead features a 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 six-part form. Plus, the exclusive OKI closed-loop feedback system ensures character-placement accuracy.
Exceptional paper-handling versatility The expandable head gap accommodates multi-part forms and cut-sheet stock, including labels and stiff index stock. The advanced zero-tear feature accurately positions continuous forms for a clean tear at the perforation, eliminating wasted stock. You can get perfect results with single sheets, index stock, labels, and envelopes – all without jams or smears.
Built to last, inside and out The ML421’s performance-optimized power supply has been enlarged to easily handle harsh printing conditions. Its energy-management capabilities match power expenditures to the 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.
Easy to use 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.
