National
12、bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Oth
13、er international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rule
14、s given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires appr
15、oval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24711 was prepared by Jo
16、int Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 28, Office equipment. This second edition cancels and replaces the first edition (ISO/IEC 24711:2006), of which it constitutes a minor revision. INCITS/ISO/IEC 24711-20072008 ITIC 2008 All rights reserved v Introduction T
17、he purpose of this International Standard is to provide a process for determining the ink cartridge yield for a given colour inkjet printer model (i.e. integrated ink cartridges and ink cartridges without integrated printheads) using a standard consumer type test suite. Ink cartridge yields determin
18、ed on one printer model and cartridge configuration are not applicable to another printer model or cartridge configuration even if the ink jet cartridges used in testing are the same. This test page suite is not focused on printing of photographs, but is intended to be a sampling of typical business
19、 consumer pages. This International Standard prescribes the following: the test method that manufacturers, test labs, etc. use to determine ink cartridge yield; the method for determination of declared yield values from the test results; and the appropriate method of describing the yield of cartridg
20、es in documentation supplied to the consumer by the manufacturer. The cartridge yield is determined by an end of life judgement, or signalled with either of two phenomena: fade, caused by depletion of ink in the cartridge, or automatic printing stop, caused by an ink out detection function. It is en
21、visioned that one of the uses of this International Standard will be for the calculation of cost per page (CPP). While this International Standard measures a portion of this cost, it is not used as the sole component of CPP calculation. Additional factors are considered for CPP calculations. AMERICA
22、N NATIONAL STANDARD INCITS/ISO/IEC 24711-20072008 ITIC 2008 All rights reserved 1 Method for the determination of ink cartridge yield for colour inkjet printers and multi-function devices that contain printer components 1 Scope The scope of this International Standard is limited to evaluation of ink
23、 cartridge page yield for ink-containing cartridges (i.e. integrated ink cartridges and ink cartridges without integrated print heads) for colour inkjet printers. This International Standard can also be applied to the printer component of any multifunctional device that has a digital input printing
24、path, including multi-function devices that contain inkjet printer components. Both liquid and solid ink products can be tested using this International Standard. This International Standard is only intended for the measurement of ink cartridge page yield when printing on plain paper. No other claim
25、s can be made from this testing regarding quality, reliability, etc. This International Standard can be used to measure the yield of any cartridge that is used in a significant amount during the printing of the test suite defined in ISO/IEC 24712. This International Standard is not for use with prin
26、ters whose minimum printable size is equal to or greater than A3 or for printers designed or configured to print photos (for example, maximum printable size less than A4 or a printer configuration intended for photo-only printing). In addition, it only applies to drop-on-demand printing systems. 2 N
27、ormative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO/IEC 24712, Colour test pa

29、his document, the following terms and definitions apply. 3.1 fade phenomenon in which a significant reduction in uniformity occurs due to ink depletion NOTE 1 In this test, fade is defined by a significant increase in lightness, L*, or a decrease in density on the bands surrounding the edge of the l
30、ast page in the test page suite (Diagnostic Page). This decrease in density does not have to occur completely across the page. This comparison is made using the second diagnostic test page generated during testing (the 10th page printed). For examples of fade, please consult Annex A. INCITS/ISO/IEC
31、24711-20072008 2 ITIC 2008 All rights reserved NOTE 2 In some printer systems, fade can occur prematurely due to the way that ink is provided to the printing system. If a printer exhibits fade, a five minute pause is allowed to provide for recovery of the ink delivery system and printing can continu
32、e. If fade appears on the next suite, then the cartridge is judged at end of life and the additional diagnostic page printed is not counted in the yield calculation. If fade does not appear on the next diagnostic page, then printing can continue until the next fade or ink out is encountered and the
33、additional diagnostic pages will be counted. 3.2 streaks very thin lines of colour, other than intended in the bands surrounding the edge of the last page in the test page suite (Diagnostic Page) NOTE Streaks differ from fade in the width and severity of increase in lightness, L*, or reduction in de
34、nsity. Streaks can appear for a number of reasons, thermal issues and clogged nozzles being two of the main causes. If these streaks occur in three consecutive diagnostic pages, then a streak removal operation is required. Comparisons are made using the phenomena sample provided in Annex B. 3.3 stre
35、ak removal operation procedure used to restore the print performance by removing streaks NOTE If streaks are observed on three consecutive diagnostic pages, first the printer can be left idle for five minutes. Then an additional three test suites are printed. If the streaks are still observed, then
36、a streak removal operation is conducted according to the latest printer manufacturer documentation. 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 prescribed in 5.2.1 2). Al
37、l test page suites printed during this process will be included in the page count for determining the yield. 3.4 print head alignment operation function that aligns newly installed print heads NOTE If it is mandatory according to the latest printer manufacturer documentation, this operation is perfo
38、rmed during testing. The pages used in the alignment procedure are not counted in the measurement of yield. 3.5 ink low warning generated by the printing system when it has determined that the amount of ink is such that a cartridge change may be required soon NOTE It does not indicate that the syste
39、m is out of ink. 3.6 ink out signal generated by the printing system when the useable ink in the system is depleted and the printer stops printing 3.7 end of life condition determined by one of two mechanisms: fade as defined in 3.1, or ink out as defined in 3.6. NOTE For cartridges with more than o
40、ne colour of ink in a single cartridge, end of life is defined when the first colour within the cartridge exhibits fade or ink out. In the event that the printer can continue printing after ink out is reported, the cartridge will still be considered at end of life. INCITS/ISO/IEC 24711-20072008 ITIC
41、 2008 All rights reserved 3 3.8 test page suite series of five pages defined by ISO/IEC 24712 that are printed consecutively as a single job, ending with a diagnostic page 3.9 individual cartridge yield value determined by counting the number of diagnostic pages (last page of the ISO/IEC 24712 test
42、page suite) printed between cartridge installation and end of life (as defined in 3.7) and multiplying by five NOTE 1 If the printer stops due to ink out in the middle of a test page suite, the number of the diagnostic pages printed is counted. Then, the first diagnostic page of the remaining print
43、job is included in the subsequent cartridge yield. NOTE 2 The number of test page suites counted may contain some pages that show visible fade. To simplify the testing, determination of end of life is only made on the diagnostic page (last page of the ISO/IEC 24712 test page suite). 3.10 declared ca
44、rtridge yield at or below the lower 90 % confidence bound of the mean as prescribed in 6.1 and 6.2 3.11 primary cartridge cartridge containing full density black, cyan, magenta or yellow ink or a combination of full density cyan, magenta and yellow NOTE These colours represent the primary inks used
45、in a traditional four-colour printing process. 3.12 supplemental cartridge cartridge other than the full density cyan, magenta, yellow and black cartridges NOTE The determination of yield for a supplemental cartridge is made according to 6.2. 4 Test parameters and conditions 4.1 Set-up Place the pri
46、nter on a horizontal surface and set-up the printer according to the installation guide provided in the printer users manual. Use the most recent printer driver available from the manufacturers website or the supplied driver with the printer. The driver version will be specified on the test report.
47、Cartridge installation shall be completed following the instructions in the cartridge installation guide. If there is a contradiction between the printer and cartridge manuals for the cartridge installation, the cartridge manual will take precedence except if changes are recommended for printer or d
48、river settings. At the start of the test, all printers shall be set-up using a set of priming cartridges to insure that the ink used in testing is primarily for printing, not for initial priming/cleaning. After the printer is set-up according to the manufacturers instructions, the priming cartridges
49、 shall be used to print a minimum of 25 pages, 5 cycles of the standard test page suite. The priming cartridges shall be removed and replaced with new cartridges that will be used for testing yield. The pages printed during this step are not counted towards yield. Even if required by the printer, print head alignment does not have to be performed on the priming cartridges. The number of pages used in the priming operation will be included in the test report. The replacement of the priming cartridges with the first test cartridges
