ML490/491

printers are the commanding solution.

They handle the printing needs of the most demanding
environments—including point-of-sale, automation
and utility applications such as wholesale or retail
sales counters, financial departments, and
manufacturing or warehouse sites. Yet they also
produce letter-quality type and high-resolution
graphics for the office and executive suite.

Unequaled performance technology.

The

ML490/491 sport features that give them a strong
edge over their predecessors as well as the
competition:

•

An internal cooling fan provides continuous airflow

for the printhead—maximizing throughput
productivity for long, unattended print jobs

•

Additional feed rollers provide precise forms

handling and printed-character placement accuracy

•

3-piece top cover provides easy access and
unsurpassed break resistance

with

letter-quality output.

Fast, with finesse.

ML490/491 printers run the

gamut of paper types and envelopes at lightning
speed—reaching 475 cps in Utility/Draft mode and
105 cps in Letter-quality. Their rugged printhead (200
million-character average life expectancy) is made up
of powerful samarium magnets and stored-energy
pins that deliver precise, sharp characters all the way
through to the last page of a 5-part form.

The patented OKI closed-loop feedback system
assures character placement accuracy. And a zero-
tear feature accurately positions continuous forms
for a clean tear at the perforation to eliminate
wasted stock.

Sturdy and sophisticated.

Field-proven reliability is

just one reason OKI MICROLINE printers are the most
widely-used impact printers in North America
