    HP Original Toners Better Than Remanufactured Toners
    oct 2008 Manila, Philippines — Following the release of a study on HP InkJet ink cartridges conducted by TÜV SÜD PSB last year, Hewlett-Packard announces the findings of yet another successful comparative cartridge testing for Asia Pacific—this time for toners.

    Conducted by technical test organization QualityLogic, the findings show that Original HP LaserJet Toner Cartridges can produce an average of 25.7% more pages, categorized as acceptable for all uses, as compared to Asia Pacific brands of remanufactured toner cartridges that were tested.

    With regards to reliability, the findings revealed that one in every four remanufactured cartridges in Asia Pacific were found dead on arrival (DOA) or failed prematurely (FP), compared to Original HP Cartridges that had no such reliability issues during testing.

    Remanufactured toner cartridges were found to have reliability and print quality issues, which were found to have an extremely high failure rate. Almost one in ten or 9.7% were either dead on arrival or failed prematurely, and 15.3% of the samples tested had half of total printed pages limited or without use.

    Key Findings
    • Reliability – Problem Cartridges
    o When combining all problem categories, HP LaserJet toner cartridges exhibited no reliability failures in the study, compared to an average of 25.0% for all remanufactured brands in the study.
    • Print Quality Page Distribution
    o HP LaserJet toner cartridges printed an average of 96.1% of sample pages categorized as acceptable for all uses, compared to 70.4% for the average of remanufactured brands tested.

    Details about the study
    HP commissioned QualityLogic to conduct a study to evaluate the print quality page distribution and reliability of HP branded LaserJet toner cartridges versus 3 brands of remanufactured toner cartridges from the Asia Pacific region. The study was completed in June 2008.  For testing, HP 10a and HP 42a black toner cartridges were used on HP LaserJet 2300 and HP LaserJet 4350 printers.

    A total of 24 cartridges (HP10A and HP42A) were tested for each brand in the study (12 each for the LaserJet 2300 and 4350 platforms). Printing was performed in a continuous mode with the following test pages: Page 1 – Business Letter, Page 2 – Spreadsheet, Page 3 – Presentation Slide, and Page 4 – Flyer. All test pages were printed using standard 8 ½ x 11 office paper.

    Cartridge print quality page distribution was determined by inspecting a sample of approximately 170 pages taken at periodic intervals over the lifespan of each cartridge. The scale used for grading sampled pages was created using data from a psychometric research study of business laser printing users.

    QualityLogic page inspectors categorized each of the sampled pages based on overall print quality, using the scale created from the psychometric study data. The inspectors were trained using the 40 page psychometric page set. The consistency of grades across inspectors was monitored on a daily basis and retraining against the psychometric page set, with known scale values, was repeated as necessary.
