SUPPORTING TEST DATA
Test Environment
This product was tested in BLI's 929-square-metre test lab, in an environment monitored by a Honeywell Temp/RH chart recorder, which
replicates typical office conditions.
Test Equipment
BLI's dedicated test network, consisting of Windows 2000 and Microsoft Exchange servers, Windows XP workstations, 10BaseT/
100BaseTX network switches and CAT5 cabling.
Test Duration
Products are tested for two months, a portion of which consists of a durability test during which the product is run at half of its
manufacturer-rated maximum monthly volume, with varying daily test volumes designed to replicate real-world use over an eight-hour
workday. This variable schedule includes a mix of various-size documents, simplex and duplex modes, and a mix of short, moderate
and long run lengths, and on/off cycles, throughout the day.
Tested Configuration
The Dell 2335dn Multifunctional Laser Printer base model.
Test Procedures
The test methods and procedures employed by BLI in its lab testing include BLI's proprietary procedures and industry-standard test
procedures, which include a BLI-developed variation of ASTM's 1318-90 Test Method for Determination of Productivity using Electrostatic
Copy Machines. In addition to a number of proprietary test documents, BLI uses an industry-standard KATUN test original for evaluating
black image quality and test suites from Quality Logic to evaluate applications compatibility. In addition to a visual observation under a
Graphiclite D5000 Standard Viewer, colour print quality is tested using a colour test target, which is read using the X-Rite Eye-One/iO
Colour Spectrophotometer, and samples are analysed using the CIE XY Chromaticity Diagram. In addition, density of black and colour
output is measured using an X-Rite 500 Series Densitometer. Georgia-Pacific Spectrum Multi-Use Paper is used in the tests, 10 percent
of which is recycled paper containing 30 percent post-consumer content. Image quality is tested using Georgia-Pacific Printing Paper.
