Built to last, inside and out. The performance-
optimized power supply of the OKI
®
MICROLINE
®
490/491 has been enlarged to easily handle harsh
printing conditions. Its energy management
capabilities match power expenditures to print-job
size, maximizing the life of the 24-pin printhead
and other components.These are just a few of the
reasons why OKI MICROLINE Impact printers are the
most widely used in North America.
1
A long-lasting rack-and-pinion drive system ensures
print quality longer than belt or cable systems.
And the ergonomically-designed, impact-resistant
chassis protects the ML490/491 from damage, even
in the toughest working environments.
All this performance is user-friendly. Controls are
conveniently placed on the front panel for fast
access.The automatic loading of continuous and cut
stock makes every print job easier, and the design of
the internal sheet separator enables easy loading of
tractor-fed paper into the rear push tractor.
OKI provides the edge in performance no competing
printer can claim—and backs it with 3 years of
warranty coverage

and a network of authorized OKI
Dealer Service Centers and Service Depots.
The high-quality, highly reliable and highly affordable
ML490/491 Impact printers from OKI. Put them to
work in your office or behind the counter—and
watch them drive your productivity to new limits while
they improve the look of your forms printing.
