1 Custom Test Report Comparative Page Yield / Reliability Evaluation SEPTEMBER 2012 Original HP Inkjet Print Cartridges vs. Third-Party Refilled Cartridges from Asia-Pacific Countries Executive Summary In August 2012, Buyers Laboratory LLC (BLI) completed a study for Hewlett-Packard (HP) designed to test the page yield and reliability performance of Original HP #60XL, #60XL, #61XL, #61XL, #802, #802, #818L, #818L, #901XL and #901 inkjet print cartridges compared to a sampling of third-party refilled cartridges. BLI hired mystery buyers to get empty HP cartridges refilled by leading refill service providers in six Asia-Pacific countries: China, India, Indonesia, Korea, the Philippines and Thailand. The empty Original HP inkjet cartridges were refilled across 18 locations at either chain stores belonging to locally recognized brands or non-branded locally recognized stores. The results of the study, in which 17 of each cartridge per brand/type were tested on 18 printers, for a total of 748 cartridges, unequivocally show that the Original HP inkjet print cartridges tested significantly outperformed the refilled ink cartridges. Page Yield: When comparing the total pages printed from all cartridges tested, it was concluded that overall Original HP inkjet print cartridges produced 116% more pages, or over twice as many pages, than the refilled cartridges tested, based on the average page yields. Cartridge Reliability: No Original HP inkjet print cartridges tested in the study were dead on arrival (DOA) or expired prematurely, whereas the refilled cartridges tested had an overall failure rate of 70%, where 45% were premature expires and 25% were DOA.

2 Lab Test Results Page Yield When comparing the total pages printed from the cartridges tested, it was concluded that overall the Original HP inkjet print cartridges produced 116% more pages than the refilled cartridges tested, based on a comparison of the average page yields.

4 Overall, the refilled black cartridges failed at a rate of 66% (32% premature expires, 34% DOA) while the tri-color refilled cartridges failed at a rate of 74% (57% premature expires, 17% DOA). With the refilled color cartridges, electrical connect failure was the most prevalent cause of DOA failures, at 33%. Other reasons for DOA failures with the refilled color cartridges included color mix (27%), failure to print color (20%), ink leakage (10%), immediate image fade (4%), streaking (4%), and cartridges that delivered less than 10 pages (2%). With the refilled black cartridges, the most prevalent cause of DOA failure was immediate image fade, at 77% of the black failures. Other reasons for DOA failure with the refilled black cartridges included electrical connect failure (12%), ink leakage (6%), streaking (4%), and failure to print black (1%). Premature expires among the refilled color cartridges were solely due to unacceptably low page yields, at 100%. The same reason was the primary cause of premature expires of the refilled black cartridges, at 82%, while streaking with black ink happened 15% of the time and cartridge failure due to electrical connect failure occurred with 3% of the black cartridges.

As can be seen, color fidelity was severely off, with yellow printing as brown, gold, orange or green; cyan printing as various shades of green; and magenta as various shades of maroon or purple. In addition, streaking such as that shown in the last three exhibits on the next page resulted in cartridges being classified as DOA as it was excessive and could not be remedied with the three streak removal procedures. 4

6 Appendix I: Test Methodology The following is a summary of the methodology used for this study: Printers and Print Cartridges Selected for this Study Printer Cartridge Cartridge HP Deskjet 2050 All-in-One Printer (CH350A) HP Deskjet D2680 Printer (CH396A) HP61XL (CH563WN) HP802 (CH563ZZ) HP60XL (CC641WN) HP818L (CN639ZZ) HP61XL (CH564WN) HP802 (CH564ZZ) HP60XL (CC644WN) HP818L (CN640ZZ) HP Officejet 4500 All-in-One Printer (CB867A) HP901XL (CC654AN) HP901 (CC656AN) A total of 578 refilled ink cartridges and 170 Original HP inkjet print cartridges were tested using a total of six HP Deskjet 2050 All-in-One Printers, six HP Deskjet D2680 Printers and six HP Officejet 4500 All-in-One Printers. These devices and SKUs represent a large range of the HP portfolio, including old, previous and current generation of product. This was done to capture a wide range of products that most users may own. It should be noted that these cartridges are also compatible with a number of other HP printer models (see table below), so the user experience reported in this report would not be limited to just three HP printer models. Compatible Printers HP 60XL & HP 61XL & HP 802 & HP 818L & HP 901XL & 901 Deskjet 1600, 2400, 2500, 2600, 4200 and 5500 Series Deskjet 1000 and 3000 Series Deskjet 1000, 2000 and 3050 Series Deskjet D2500, D2600, D5560, F4200 Series Officejet 4500 and 4600 Series Deskjet 4400 and 4500 All-in-One Series Deskjet 200 All-in-One Series Deskjet F4400 All-in-One Printer Series Envy e-all-in-one Series Photosmart 4600 and 4700 All-in-One Series Photosmart e-all-in-one Series Printing was performed in a continuous mode in a controlled environment using the ISO/IEC five-page color test suite, and the environmental conditions specified in ISO/IEC To account for reliability-driven cartridge issues, defective cartridges were included in the page yield calculations. Consequently, the reported page yield numbers are not based on the ISO/IEC standard, as ISO/IEC requires that defective cartridges are excluded from the page yield calculation. This was done to account for the negative user experience with defective or failed cartridges. 6

7 The ISO/IEC Test Suite Printers were supplied by HP. BLI procured all paper and Original HP inkjet print cartridges. To test cartridges refilled by refill service providers, new HP cartridges were prepared for refilling by printing the ISO test suite to the first sign of fade. This is consistent with re-filler recommendations that cartridges to be refilled not be completely emptied. BLI then sent the empty cartridges to six countries in the Asia-Pacific region in vacuum-tight containers to prevent any undue effects. Upon receipt, the mystery buyers in those countries took cartridges to multiple locations of each cartridge refiller service provider. Refill service provider cartridges were tested in BLI s Hackensack, NJ, test facility. For the refill service providers tested, 100% of the test data is based on cartridges that had been refilled once. Pages printed while preparing cartridges for refilling were not part of the test. Buyers Laboratory selected Georgia-Pacific Spectrum Multi-Use plain paper (8½ x 11, 20 lb., 92 Brightness) for all printing in this study. Each cartridge was inspected for leaks or other damage upon entering the test, and a cartridge with substantial visible ink spilled in the bag or on the cartridge was declared DOA. All other cartridges were printed to End-of-Life (EOL; see study definitions in Appendix II). Lab testing at BLI Printing continued until all test cartridges reached EOL. and black cartridges were tested in 7

8 parallel. As the color or black cartridges reached EOL, Original HP substitute cartridges were used to complete the testing of the unfinished refilled cartridge in the set. All results and effects of these Original HP substituted cartridges were ignored in the study. This study tested average performance of the market, not individual brand performance. The brands and providers in the sample were included because, together, they make up a significant portion of the overall market for refilled cartridges in Asia-Pacific countries. Seventeen cartridges of each type were tested for HP, and a total of 51 cartridges of each type were tested for re-fillers in China, India, Indonesia, Korea and Thailand, while a total of 34 cartridges of each type were tested for re-fillers in the Philippines.

9 Appendix II: Definitions: Test Project Terminology End-of-Life (EOL) Individual Cartridge Yield Average % More Pages Dead On Arrival (DOA) Early End of Life (Premature Expire) Definition A condition determined by one of six mechanisms: 1. Fade has occurred on the diagnostic page per ISO definition. 2. Significant reduction in density in the bands or blocks per ISO definition. 3. Streak removal procedure steps have been exhausted per ISO definition. 4. Significant leakage before or during installation or any time during printing consecutive pages with color mix. 6. Cartridge fails to print or stops printing and efforts to recover are unsuccessful. Individual cartridge yield is calculated by counting the number of diagnostic pages printed between cartridge installation and EOL, then multiplying by five. The diagnostic page is the last plot printed in the test suite. Percent More Pages is calculated for each cartridge type for each model: 100 x (HP Page Yield Refilled Page Yield)/ (Refilled Page Yield). From these calculations the Average Percent More Pages was obtained, which is defined as percent more pages printed by all HP cartridges versus all aftermarket cartridges tested. Note that these are simple averages and not weighted averages. A condition determined by one of three mechanisms: 1. Cartridge found to have substantial leakage (as defined above) at start or during testing or fewer pages printed by a cartridge before end of life. 3. Cartridge fails to operate upon installation. A cartridge that has a page yield of less than 75% of the HP published page yield for that cartridge model in the test. Fade A significant decrease in density on the bands or blocks of the last page in the test page suite, which is a diagnostic page. This decrease in density does not have to occur completely across the page to be considered fade. For a comparison to determine if fade is occurring, reference the 10th page printed by that printer. Fade Fade 9

10 Mix Defined as a color cartridge that cannot print the correct Cyan, Magenta and Yellow colors as shown on the diagnostic page 5 of the page yield test suite. Ink has mixed in an unintended manner inside the cartridge and has caused a discoloring of the ink. An example of Mix is provided to the right. Compare the colored blocks in the correct example to those of the color mix page. Correct Diagnostic Page Mix Streaks Very thin lines of color or the lack of color where it should be, in the blocks surrounding the edge of the diagnostic page. Streaks differ from fade in the width and severity of the reduction in density. Streaks can appear due to a number of reasons, including thermal issues and clogged nozzles. Streaking Streaking Streak Removal Procedures This is the cartridge cleaning procedure (servicing) used to restore print performance. If streaks were observed on three consecutive diagnostic pages, a streak removal procedure was implemented. Streak removal operations were conducted according to the HP printer manual documentation. If there were additional cleaning steps advised for non- HP cartridges, these were included within the cleaning process. 1. If the cleaning operation has the option of multiple cleaning strengths, the procedure indicated in the printer manual for resolving streaking should be followed. 2. Use of a light and a strong cleaning procedure counts as one cartridge cleaning operation. 3. Cleaning is verified by the reprinting of the diagnostic plot. If streaks are still present, the cleaning procedure is repeated. 4. Any pages printed during the nozzle cleaning operation are not counted in the yield calculation. Due to the significant amount of ink that is used for cleaning, the maximum permissible number of times that the streak removal operation can be used on a given cartridge is three (3). Cartridges which require a fourth service are considered to be at EOL. All cleaning steps were recorded and reported by cartridge, i.e. page number streak occurred on, number and types of services required and result (e.g., whether or not the cartridge recovered). A cartridge not demonstrating streaking or other problems but which has experienced three (3) cleanings because the other cartridge in the sku pair has experienced streaking was not considered to be at EOL. 10
