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.

The ML590/591 offers seven
resident typefaces including
Courier, SwissTM and Roman,
each scalable from 8 to 64

increments. It also
has a resident
PostNetTM Bar
Code for mailing
envelopes, along
with seven other
bar codes.
The ML590/591
has accessories to
impact on your
productivity. For example, the
Bottom Feed Push Tractor Kit
provides a straight-through, jam-
free paper path for thick forms,
letting you take full advantage
of the printer’s short tear-off
form capabilities.
The printer has a Cut Sheet
Feeder for unsupervised printing
of letterheads and envelopes. Its
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 tech-
nology and product-enhancing
versatility. To handle your
office needs, it’s one “smart”
impact printer.
