Product Overview

This rugged and reliable forms printer combines versatile paper handling, fast throughput, and a small footprint.

The OKI® MICROLINE® 186 has a way with tough conditions. This compact forms printer actually thrives in industrial and point-of-sale environments because it’s built to meet the renowned OKI standards for quality and Tank-Tough® reliability. As proof, the ML186 has a 20,000-hour MTBF rating, more than triple that of its closest competitor. Just put it to work and see for yourself how it delivers!

The printer’s small footprint makes it ideal for use in your system configuration. And the operator panel control of character sets, form length, and other frequently used functions makes the ML186 quite easy to use. (The printer has a “lockout” feature to prevent unauthorized setting changes.) OKI provides the edge in quality and reliability no competing printer can claim. It’s the reassurance that comes with the backing of a full 3-year warranty and a network of authorized OKI Dealer Service Centers and Service Depots.

Demand only the best. Put the rugged, affordable MICROLINE® 186 to work in the shop or behind the counter. Today.

Small Package, Big Performance

 Sony a580 For its size and weight, the ML186 is fast—375 cps in SuperSpeed Draft mode. It also combines efficiency with economy. It’s packed with advanced, field-proven technology, including a patented OKI closed-loop optical sensor that accurately positions the printhead, ensuring precise characters even on the last page of a 5-part form. The ML186 sports our rack-and-pinion drive system for dependable throughput and longer wear, a sturdy 200 million-character printhead that’s designed to deliver output speeds 25aster than its predecessor, and a 16-bit CPU for even quicker processing.

Exceptional Paper Handling

 Sony a580 The ML186 can print virtually any continuous or sheetfed form—including “difficult” media: its pinfeed platen moves card stock and labels effortlessly, along with multi-part forms up to 10" wide. A short, straight paper path reduces the possibility of media jamming. Continuous forms and single sheet paper (e.g. letterhead) feed smoothly through the rear or top. And the optional Pull Tractor Kit handles media from 3" to 9.5" wide.

All That and It’s Easy to Use, Too!

 Sony a580 Walk up to the ML186 and select your character sets, form length, and line feed setting—right from the operator panel. It couldn’t be easier. For the next generation in forms-printing performance, specify the OKI ML186. Unlike most other industrial and POS printers, the ML186 offers both bottom-feed and short-tear standard, so you can remove forms right at the perforation every time, which means the next form isn’t wasted.

Getting the Job Done. Easily.

 Sony a580 Whatever the need or the workload, the ML186 sets an impressive pace. Select any of four speed settings and get a quality product in less time. Fastest is the blazing 375 cps “Super Speed” Draft mode, followed by the 333 cps High-Speed Draft, 250 cps Utility, and the Near-Letter Quality of 62.5 cps. If you process your information over long distances, the ML186 has an option that can save time and expense: an OkiLAN® 10 Base-T Ethernet external print server that lets you connect over the Internet using TCP/IP protocols.
