20、 revision.iv ISO/IEC 2015 All rights reservedBS ISO/IEC 24711:2015ISO/IEC 24711:2015(E) Introduction The purpose of this International Standard is to provide a process for determining the ink cartridge yield for a given colour inkjet print system (i.e. integrated ink cartridges and ink cartridges wi

21、thout integrated printheads) using a standard consumer type test suite. In the case where a cartridge set can be used in multiple printer models, only one yield test needs to be performed as long as the difference between printer models does not impact yield. NOTE A cartridge supplier may choose to

22、use more than one market identifier for a single physical cartridge. In this case, only one yield test is required as long as there are no differences in the cartridges other than market identifiers. This International Standard prescribes the following: the test method that manufacturers, test labor

23、atories, 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 cartridges in documentation supplied to the consumer by the manufacturer. The cartridge yield is determined by an end

24、-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 envisioned that one of the uses of this International Standard will be for the calculation of cost per page (CP

25、P). 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.

26、ridge 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 cartridge page yield for ink- containing cartridges (i.e. integrated ink cartridges and ink cartridges without integrated

27、 printheads) for colour inkjet print systems. This International 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

28、 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 claims can be made from this testing regarding quality, reliability, etc. This International Standard can be used to measu

29、re 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 printers whose minimum printable size is equal to or greater than A3 or for printers designed or configured to print phot

30、os (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 Normative references The following documents, in whole or in part, are normatively referenced in this document and are

31、 indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

33、apply. 3.1 fade phenomenon in which a significant reduction in uniformity occurs due to ink depletion Note 1 to entry: 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 last page in the test page suite (Diagnos

34、tic 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. INTERNATIONAL ST ANDARD ISO/IEC 24711:2015(E) ISO/IEC 2

35、015 All rights reserved 1BS ISO/IEC 24711:2015ISO/IEC 24711:2015(E) Note 2 to entry: 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

36、system and printing can continue. 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

37、ink out is encountered and the 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 1 to entry: Streaks differ from fade in the width and severity of in

38、crease in lightness, L*, or reduction in density. 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 phe

39、nomena sample provided in Annex B. 3.3 streak removal operation procedure used to restore the print performance by removing streaks Note 1 to entry: If streaks are observed on three consecutive diagnostic pages, first the printer can be left idle for five minutes. Then an additional three test suite

40、s are printed. If the streaks are still observed, then 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

41、used on a given cartridge is prescribed in 5.2.1. Note 2 to entry: All test page suites printed during this process will be included in the page count for determining the yield. 3.4 printhead alignment operation function that aligns newly installed printheads Note 1 to entry: If it is mandatory acco

42、rding to the latest printer manufacturer documentation, this operation is performed 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

43、 cartridge change may be required soon Note 1 to entry: It does not indicate that the system 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:

44、 fade (3.1) or ink out (3.6) Note 1 to entry: For cartridges with more than one 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 cartridg

45、e will still be considered at end of life. 3.8 test page suite series of five pages defined in ISO/IEC 24712 that are printed consecutively as a single job, ending with a diagnostic page2 ISO/IEC 2015 All rights reservedBS ISO/IEC 24711:2015ISO/IEC 24711:2015(E) 3.9 individual cartridge yield value

46、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 (3.7) and multiplying by five Note 1 to entry: If the printer stops due to ink out in the middle of a test page suite, the number of the diagn

47、ostic pages printed is counted. Then, the first diagnostic page of the remaining print job is included in the subsequent cartridge yield. Note 2 to entry: 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 on

48、ly 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 containing full density black, cyan, magenta or yellow ink or a combina

49、tion of full density cyan, magenta and yellow Note 1 to entry: These colours represent the primary inks used in a traditional four-colour printing process. 3.12 proxy cartridge primary cartridge to be utilized for estimating yield of supplemental cartridges (3.13) 3.13 supplemental cartridge cartridge other than the full density cyan, magenta, yellow and black cartridges Note 1 to entry: The determination of yield for a supplemental cartridge is made according to 6.2. 4 Test parameters and conditions 4.
