Tank Tough reliability and expanded head gap for dedicated forms printing

The MICROLINE 320/321 Turbo builds on the heritage of Tank-Tough reliability established by OKI's ML320/321, our best-selling dot matrix printer all around the world.

This 9-pin dot matrix printer is blazing new trails in productivity. Engineered for dedicated printing in the most demanding point-of-sale, automation and utility applications, the ML320/321 Turbo can easily run twice as long as most printers in its class! It can simplify any job on virtually any stock, and it's economical enough to put wherever you need data on the spot.

The ML320/321 Turbo puts the "work" in workstations for financial departments, wholesale or retail sales counters, even for warehouse or manufacturing environments.

Set it up with a box of forms even 6-part invoices! and let it run and run and run.

Its relentless performance comes from the rugged printhead design that keeps your print images sharp for a 200-million character life. A lighter, stronger, more efficient motor reduces friction, heat build-up and wear. The long-lasting rack and pinion drive system ensures print quality longer than belt or cable systems. Plus, an impact-resistant chassis protects the entire mechanism, even in the harshest environments.

When it comes to endurance, dependability and efficiency, the ML320/321 Turbo sets a new standard.

Unmatched paper-handling capability

Specifically designed to offer enhanced paper-handling capabilities, the ML320/321 Turbo can be set with an expanded gap between printhead and platen, accommodating multi-part forms and stock that are up to twice as thick as those that fit our nearest competitor. A bottom feed feature* keeps the paper path short and straight when running stiff card stock or labels.

The ML320/321 Turbo printhead has a lightweight samarium cobalt magnet and powerful, spring-activated pins to deliver a stronger punch right to the last page of a 6-part form!

For precisely formed output, a patented optical sensor accurately positions the printhead on the page, first time and every time. And the auto-tear feature accurately positions continuous forms for a clean tear at the perforation eliminating wasted forms.

This reliable, flexible 9-pin dot matrix printer can meet your needs today and in the future, because it's the perfect replacement for the ML320/321. It's exactly the same size, built to stand up to harsh factory conditions, and is compatible with virtually all custom and "off-the-shelf" software.

The ML320/321 Turbo. A lot of tank-tough performance for dedicated forms printing.

* Requires optional push tractor
