EVALUATE 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 throughput. 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 environment, send a mix of

black-and-white and color documents of different length and complexity to the printer over a stan-

dard 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 reliably. A color

printer must keep up with the performance demands of a shared network 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 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.
