Section 2: Evaluating Colour Laser Printers
Evaluating Productivity
A colour printer's overall productivity represents the sum of many of its
specifi c capabilities.
other factors play an important role in determining whether a printer can support a
busy work group, 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 colour printing, rather than black
and white printing, is the primary use for
this class of colour printer, it makes sense
to pay close attention to the colour 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 fi nished.
Calculate print job throughput
Print job throughput is the time it takes
from clicking the print button on your
computer screen to the fi nal 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
maximising throughput. Test against
jobs typical of your work environment –
do you regularly print large, image and
colour intensive images that place an
emphasis on RIP speed? Or, does your
business regularly print runs of 25,
50 or hundreds of colour documents
or presentations?
Print speed is an obvious specifi cation to compare, but many
Measure overall performance
To accurately measure overall printer
performance in a real work group
environment, send a mix of black and
white and colour documents of different
length and complexity to the printer
over a standard Ethernet network. This
combines the network transmission
time, fi rst-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 colour printer must be able to handle
a wide variety of documents quickly
and reliably. A colour printer must keep
up with the performance demands of a
shared network environment, and be able
to process jobs quickly and effi ciently
to keep from becoming a productivity
bottleneck.
Consider media fl exibility
Think about the various document
types your business could generate
in-house, and ensure the printer you
are considering 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
artists and general offi ce users will be
pleased with its print speed and ability to
process jobs quickly and effi ciently and
support a busy, networked environment.
Print Speed
The Phaser 7760 printer, at up to 35
ppm in colour and 45 ppm in black and
white, is one of the fastest colour printers
designed for use by colour professionals
and graphics-intensive offi ces – up to
®
46% faster than the HP
printer in colour and 88% faster in black
and white.
Print job throughput
With many years of experience, Xerox
has developed one of the most effi cient
RIPs (Raster Image Processor) in the
industry. Combine that with an 800
MHz image processor and the result is
an impressive fi rst-page-out time of as
few as 9 seconds for colour. The resulting
productivity means your prints can
be fi nished while competitors are still
processing the image.
