QualityLogic Completes Worldwide Reliability Comparison Studies for Inkjet and Color Toner Cartridges
Study Compares OEM Supplies to Refilled/Remanufactured Brands From North America, Europe, and Asia
MOORPARK, CA — 04/2006 — QualityLogic (www.qualitylogic.com), a leading provider of QA and QC test tools and services for the imaging and telecommunications industries, today announced the completion of two studies comparing the reliability and quality of original HP print cartridges to refilled/remanufactured ink and color toner cartridges. These studies were commissioned by HP and executed by QualityLogic in its test labs.
The results of the inkjet study showed that nearly one out of six refilled cartridges were either dead on arrival or failed prematurely. Seventy percent of refilled cartridges exhibited reliability problems compared to only 2% of HP cartridges. Common problems were leaking cartridges, cross contaminated colors, and cartridges that printed no pages. In addition, the tested refilled cartridges averaged more than three times the number of low-quality pages than the HP cartridges, when looking at the percent of low-quality pages printed for each brand.
The results of the color toner study showed that when combining all problem categories, an average of 80% of all tested remanufactured color toner cartridges exhibited reliability problems, compared to less than 2% of the tested HP cartridges. HP’s original cartridges also printed more than four times the number of high-quality pages than the average of all tested remanufactured cartridges, based on pages randomly sampled.
“This QualityLogic study reveals the striking difference between original HP supplies and alternative brands — using data based on a thorough, independent analysis of inkjet and color laser print cartridges,” said James Mater, QualityLogic president and CEO. “The QualityLogic team conducted extensive testing, and meticulously analyzed and compiled results using more than 800 ink and toner cartridges and printing more than 700,000 pages.”Testing Methodology
QualityLogic procured all printers, paper, and HP print cartridges through standard retail channels. Refilled/remanufactured print cartridges were obtained through multiple retail channels where possible or directly from the manufacturer.
Test pages were designed by QualityLogic using popular application packages from Adobe, Corel, and Microsoft to achieve a balanced representation of printing samples.
Cartridge print quality and reliability for each brand were determined by inspecting printed pages to determine the print quality (PQ) of the page. Each page inspected was rated on a scale of 1 to 5 (with 5 being “best”) to determine the PQ level of that page. Pages classified with a PQ level of 4 or 5 were considered “high quality” and pages classified with a PQ level of 1, 2, or 3 were considered “low quality.”
HP color toner cartridges were compared to 12 brands of remanufactured color toner cartridges for the HP Color LaserJet 4650 (Q3668A) printer. A total of 376 remanufactured cartridges and 52 HP cartridges were tested. Brands tested were from North America (6 brands), Europe (5 brands), and Asia Pacific (1 brand).
HP inkjet print cartridges were compared to 13 brands of refilled inkjet print cartridges for the HP DeskJet 6122 (C8954A) and HP PSC 1350 (Q3501A) printers. A total of 390 refilled print cartridges and 50 HP print cartridges were tested. Brands tested were from North America (8 brands), Europe (4 brands), and Asia Pacific (1 brand).
