Oki MICROLINE 491n Dot Matrix Printer Features
Fast, With Finesse MICROLINE 491n printer runs the gamut of paper types and envelopes at lightning speed—reaching 475 cps in Utility/Draft mode and 105 cps in Letter-quality. Therugged printhead (200 million-character average life expectancy) is made up of powerful samarium magnets and stored-energy pins that deliver precise, sharp characters all the way through to the last page of a 5-part form. The patented OKI closed-loop feedback system assures character placement accuracy. And a zero-tear feature accurately positions continuous forms for a clean tear at the perforation to eliminate wasted stock.
Durable and Stylish Field-proven reliability is just one reason OKI MICROLINE printers are the most widely-used impact printers in North America.The rugged, reliable 491n printer is sure to win you over, too!
Built To Last The performance-optimized power supply of the OKI MICROLINE491n has been enlarged to easily handle harsh printing conditions. Its energy management capabilities match power expenditures to print-job size, maximizing the life of the 24-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 491n from damage, even in the toughest working environments.
Impressive, User-Friendly Performance 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.
