13、08 All rights reserved Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International S

14、tandards 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. Other international organizations, governmental and non-governmental, in liaison with ISO

15、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 rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committ

16、ee 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 approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the

17、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 Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 28, Offi

18、ce equipment. This second edition cancels and replaces the first edition (ISO/IEC 24711:2006), of which it constitutes a minor revision.

19、IHS-,-,-INCITS/ISO/IEC 24711-20072008 ITIC 2008 All rights reserved v Introduction The 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

20、printheads) using a standard consumer type test suite. Ink cartridge yields determined 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 focu

21、sed on printing of photographs, but is intended to be a sampling of typical business 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 f

22、rom the test results; and the appropriate method of describing the yield of cartridges 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 cart

23、ridge, or automatic printing stop, caused by an ink out detection function. It is envisioned 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

24、 of CPP calculation. Additional factors are considered for CPP calculations.

26、ction devices that contain printer components 1 Scope The scope of this International Standard is limited to evaluation of ink cartridge page yield for ink-containing cartridges (i.e. integrated ink cartridges and ink cartridges without integrated print heads) for colour inkjet printers. This Intern

27、ational Standard can also be applied to the printer component of any multifunctional device that has a digital input printing path, including multi-function devices that contain inkjet printer components. Both liquid and solid ink products can be tested using this International Standard. This Intern

28、ational Standard is only intended for the measurement of ink cartridge page yield when printing on plain paper. No other claims 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 significa

29、nt amount during the printing of the test suite defined in ISO/IEC 24712. This International Standard is not for use with printers 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

30、 printer configuration intended for photo-only printing). In addition, it only applies to drop-on-demand printing systems. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undat

31、ed references, the latest edition of the referenced document (including any amendments) applies.

32、photographic printers and multi-function devices that contain printer components 3 Terms and definitions For the purposes of this 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, f

33、ade is defined by a significant increase in lightness, L*, or a decrease in density on the bands surrounding the edge of the last 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 diagno

34、stic test page generated during testing (the 10th page printed). For examples of fade, please consult Annex A.

35、11-20072008 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 continue.

36、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 add

37、itional 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 densi

38、ty. 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 streak

39、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 a s

40、treak 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). All t

41、est 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 performe

42、d 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 system i

43、s 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 one

44、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. Copyright American National Standards

46、ngle 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 page suite) printed between cartridge installation and end of life (as defined in 3.7) and multiplying by five NOTE 1 If the printer

47、 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 job is included in the subsequent cartridge yield. NOTE 2 The number of test page suites counted may contain some pages that show vi

48、sible 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 cartridge 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
