On the fast track of impact printers, the MICROLINE

®

390/391 Turbo is in the passing lane. Its Tank-Tough

®

endurance in the OKI

®

tradition will keep you

productive long after most of the other printers 
in its class have retired. And its combination of
versatile paper handling, performance and speed 
can’t be matched.

Whether it’s called on to handle long print runs 
or a single piece of letterhead, an envelope or 
a spreadsheet, in the office or on a counter, the
ML390/391 Turbo is the way to go. This 24-pin
dynamo excels in dedicated forms printing, turning 
it out equally fast and precise with pin feed or cut
sheet stock.

In time trials, the ML390/391 Turbo clocks speeds 
up to 30% faster than its closest competitor — 

Powerful performance

and smooth handling

with a Utility mode that can kick out reports at an
impressive 390 characters per second. Even the 
Letter Quality mode is 30% faster than the
competition!

The ML390/391 Turbo printhead’s lightweight
samarium cobalt magnet and powerful, spring-
activated pins deliver a stronger punch, and the
expandable gap between the printhead and platen
easily seats 4-part forms. In fact, it can accept stock
that’s up to twice the thickness its nearest competitor
can accommodate. For stiff card stock or labels, its
bottom feed

provides a short, straight paper path to

keep even the most difficult jobs running smoothly.

Reliable forms printing for increased productivity 
in general office and utility applications.
