2. There was a time when all of this was
impossible from a device but not anymore!
Introducing the OKI C941. Now there is a new
multimedia production platform that makes this
and more all possible. The OKI C941 is the
solution to address these challenges. With its
small footprint the C941 packs the punch you
need to get your customers attention and wow
them in CMYK plus White or Clear.
Multimedia: Media Flexibility
The OKI C941 can produces a wide range of
applications on a wide variety of paper stocks,
weights and sizes. Our advanced LED
technology and straight paper path allow the
C941 to achieve faster print speeds in color
and monochrome with minimal paper jams,
and smooth handling.
When it comes to variety, size and thickness of
media, the C941 greatly extends the OKI
heritage of media support. The C941 easily
handles medias up to 360 gsm card stock, 14
mil polyester, 20 point magnetic media all in
sizes ranging from 3" x 5" index cards to 13" x
52” banners.
Need to print short run full color envelopes? In
addition to printing heavy weight medias from
the MPT, the C941 can accommodate a short
stack of envelopes from multi purpose tray
ensuring your letterheads & envelopes are an
exact match. Depending on the thickness as
many as 100 envelopes can be placed in the
MPT tray to handle ultra short run requests.
Production: Short-Run Color Printing
The C941 has affordable digital short-run
capabilities—with the added flexibility of being
able to apply white or clear toner. Produce high
quality short run digital prints at up to 50 ppm.
With the optional white toner you now have the
ability to print on many different substrates from
clear to dark media. Additionally, with the ease
of changing over to clear toner in as little as 2
minutes customers can let their creativity take
over by applying spot, flood or watermark gloss
effects selectively with eye-catching results.
Platform: Robust 5 Color Digital Device
This is not an office copier! The newly designed
C941 is a robust digital print engine and is
driven by an aggressive effort to create a
productive, robust and affordable device. It
features short-run capacities, production class
speed, high image quality and delivers stunning
color output in CMYK plus white or clear
across the widest range of medias and with the
addition of the optional EFI Fiery® XF Server
customers can take their output to the next
level with enhanced color management and
simplified workflows.
The C941 is a formidable, digital print device
with built in features like Auto Media Detect
which automatically adjusts the printer to your
required media weight, and Auto Color Balance
which ensures that output remains consistent
from start to finish. The C941’s new
intermediate transfer belt, and new fuser
design also ensures that our genuine OKI HD
Polymer based toner fuses consistently and
reliably every time!

Aeroshells and
parachutes helped
decelerate the
landers as they
descended through
the Martian
atmosphere.
The rovers were designed to take
panoramic images that will help
reveal the geologic history of the planet.
Each performed a variety of scientific
operations during the course of its
90-day mission.
The rovers landed
on opposite sides
of Mars—at sites
chosen for their
high-value research
potential—that
appear to have been
affected by liquid
water in the past.

Spirit launched from Space

A star scanner and sun sensor
allow each spacecraft to chart a
course through continuous
analysis of the position of the
sun and other stars in relation to
itself.
Free from the earth’s
atmosphere, space-borne
telescopes can reveal
spectacular images of
unknown regions of our
universe.
One goal of the Rover program
is to determine the feasibility
of future manned missions to
Mars, based on environmental
conditions and the availability
of water.
Two aluminum-lined tanks
carry hydrazine propellant,
allowing navigators to keep
the spacecraft closely on
