Oki ML591 User Manual

The MICROLINE®590/591 acts like a

mind reader. A smart one. This letter-

quality printer anticipates and conforms

to all your paper-

handling needs.

The difference

is OKISMART

Paper HandlingTM,

a unique patented

technology that allows

the ML590/591 to “read and learn” the

paper you feed it, then set the head gap

to the optimum distance for best print

quality. It also means less time to load

and reload paper stock, and can lead

to longer printer life.

The ML590/591 delivers perfect

output on letterheads, card stock,

forms with up to 5 parts, and labels.

And, unlike ordinary printers, the

ML590/591 takes on envelopes like any

other paper media. Just

feed them into the printer and

they emerge flawlessly printed, with

no jams or smears.

A patented sensor built into the

ML590/591 printhead calculates the

precise time and impact needed to

print each dot, virtually eliminating

uneven printing. The shape of each dot

is more consistent, producing smooth,

characters and stunning graphics. There

are no gaps, no smears or light spots,

regardless of paper type used.

You get the professional look you

want for every application, the print-

head lasts longer, and the printer works

quieter and uses less power.

Pull Tractor handles all your demanding printing applications. And it comes with an acoustic

cover for even quieter

operation.

All this and a talent with color, too: an optional,

user-installable Color Kit for the

ML590/591 coupled

with your color soft-

ware package lets you

work in a rainbow of

colors, adding impact to graphics, charts, transparencies and text presentations.

The ML590/591: a combination

of superior output, unique technology and product-enhancing versatility. To handle your office needs, it’s one “smart” impact printer.
