Evaluating laser all-in-one products 13
Fast scanning
The 50-sheet ADF processes input at up to 19 images per minute (ipm). The letter/A4-size, 24 bit, flatbed
scanner precisely scans single sheets and material such as bound documents, books, and placards.
Evaluation
Creating samples
First, develop a group of sample documents that represent what the end-user typically prints. This is the best
method for determining if a product is suited to your environment.
When evaluating performance, your print samples should include multiple documents and file types, each
created in the applications that will be used by the end-user. The samples should have different elements
(text, graphics, and photographic images) and should vary in complexity and page length. Some suggested
content includes simple text documents, mixed text and graphics, and complex graphics containing
photographic images.
CAUTION!
Using only one application or file can skew test results. Use several types of files and
applications to present a broad and realistic performance picture.
Different manufacturers provide different print quality modes. Try to compare similar modes to achieve a
fair comparison.
To evaluate the print quality and speed of text documents, such as those created in Microsoft Word and
Excel, you should print them in different print modes. Documents such as newsletters intended for circulation
or image files, where photo quality is desired, are preferably printed in the best mode.
When evaluating more than one product, it is crucial that you make a fair comparison between products.
•
Print from identical computer systems to ensure speed variations are not due to differences in processing
power.
•
Print the same files on all devices, using the same paper type and the same or equivalent settings. Print
modes need to be tested separately for each device and compared respectively.
•
Use the same operating system and software application and test comparable print drivers. (Each of
these components interacts with the printing process and can affect performance.)
Simple—text only
Mixed—from complex text
to a mixture of text and
medium-complexity graphics
Complex—images and
advanced graphics (using
overlays or fill patterns)
