SUPPORTING TEST DATA
Test environment
This product was tested in BLI's 929-square-metre U.S. test lab, in an environment monitored by an Extech RH S20 Digital RH/
Temperature Recorder and Honeywell Model 61 Seven-Day Temperature/Relative Humidity Chart Recorder. All products lab
tested by BLI are powered by dedicated circuits that are protected by ESP (Electronic Systems Protection, Inc.) surge protectors
to prevent transient power and communication disturbances from affecting equipment under test.
Test equipment
BLI's dedicated test network, consisting of Windows NT 4.0, 2000 and Microsoft Exchange servers, Windows 2000 and XP
workstations, 10BaseT/100BaseTX network switches and CAT5 cabling.
Test Duration
Products are tested for two months, five weeks of which consists of a durability test during which the product is run at its
manufacturer-rated maximum monthly duty cycle, with 25 percent of the test volume comprised of copy jobs and 75 percent
comprised of print jobs. BLI's daily test usage is designed to replicate real-world use over an eight-hour workday, and as such
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. The durability evaluation also includes testing of the document feeder/scanner in simplex and
duplex modes for an additional 20 percent of the monthly maximum volume, evenly divided over the course of the test. Imaging
media includes virgin multi-use paper. Recycled multi-use paper comprised of 30%, 50% and 100% post consumer waste is
also tested for up to 10% usage of each of the recycled media types.
Tested Configuration
Samsung MultiXpress C9250ND base unit, plus optional PostScript emulation, 3,250-sheet booklet finisher, dual-cassette
feeder and high-capacity feeder.
Test Procedures
The test methods and procedures employed by BLI in its lab testing include BLI's proprietary procedures and industry-standard
test procedures, including 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, colour print quality is tested using the ANSI standard IT8 Colour Test Target, which is read using the
Minolta CM503I 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 428 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.
