Section 2: Evaluating Color Laser Printers
Evaluating Productivity
A color printer's overall productivity represents the sum of many of its specific
capabilities.
Print speed is an obvious specification to compare, but many other factors
play an important role in determining whether a printer can support a busy workgroup,
deliver the performance you expect and meet the demands of your users. This criteria
set will help you evaluate all aspects of a printer's productivity, and show how the
Phaser 7760 printer can help you increase the productivity of your employees.
Consider print speed
Since color printing, rather than black-and-
white printing, is the primary use for this
class of color printer, it makes sense to pay
close attention to the color print speed. For
larger print jobs and longer print runs, the
rated engine speed of the printer will play
a large role in how quickly the job
is finished.
Calculate print job throughput
Print job throughput is the time it takes
from clicking the print button on your
computer screen to the final delivery of the
document to the output tray – sometimes
called "click-to-clunk." Rated print speed is
only a part of the time it takes to print a
job – image-processing speed can be even
more important to maximizing through-
put. Test against jobs typical of your work
environment – do you regularly print large,
image and color intensive images that
place an emphasis on RIP speed? Or, does
your business regularly print runs of 25,
50, or hundreds of color documents
or presentations?
Measure overall performance
To accurately measure overall printer
performance in a real workgroup environ-
ment, send a mix of black-and-white and
color documents of different length and
complexity to the printer over a standard
Ethernet network. This combines the
network transmission time, first-page-out
time, and multi-copy engine speed to
paint a clear picture of the actual overall
performance of the printer.
Consider multiple users
A color printer must be able to handle a
wide variety of documents quickly and reli-
ably. A color printer must keep up with the
performance demands of a shared net-
work environment, and be able to process
jobs quickly and efficiently to keep from
becoming a productivity bottleneck.
Consider media flexibility
Think about the various document types
your business could generate in-house,
and ensure the printer you are consider-
ing can support the type of paper or other
media you would like to use to produce
that document. Things to keep in mind
as you evaluate this area are media size,
media weight, whether you'd prefer to use
custom-sized media, and how the printer
is able to communicate the media it has
loaded to users via the print driver.
How the Phaser 7760 exceeds the
productivity requirement:
The Phaser 7760 printer is the latest in
a line of highly-performing graphic-arts
oriented printers from Xerox. Graphic art-
ists and general office users will be pleased
with its print speed and ability to process
jobs quickly and efficiently and support a
busy, networked environment.
Print Speed
The Phaser 7760 printer, at up to 35 ppm
in color and 45 ppm in black-and-white, is
one of the fastest color printers designed
for use by color professionals and graphics-
intensive offices – up to 46% faster than
the HP
LaserJet
9500 printer in color

and 88% faster in black-and-white.
Print job throughput
With many years of experience, Xerox has
developed one of the most efficient RIPs
(Raster Image Processor) in the industry.
Combine that with an 800 MHz image
processor and the result is an impressive
first-page-out time of as few as 9 seconds
for color. The resulting productivity means
your prints can be finished while competi-
tors are still processing the image.
