12、 includes Technical Corrigendum ISO/IEC 19798:2007/Cor. 1:2012.DIN ISO/IEC 19798:2014-11 4 Method for the determination of toner cartridge yield for colour printers and multi-function devices that contain printer components Introduction The purpose of this International Standard is to provide a proc
13、ess for determining the cartridge page yield for a given colour electrophotographic printer model (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) using a standard office consumer type test suite. This test suite is not focused on printing of photographs, but is inten
14、ded to be a sampling of typical office consumer pages. This International Standard prescribes the following: the test method that manufacturers, test labs, etc. use to determine cartridge yield; the method for determination of declared yield values from the test results; and the appropriate method o
15、f describing the yield of cartridges in documentation supplied to the consumer by the manufacturer. The cartridge yield is determined by an end of life judgment, or signalled with either of two phenomena: fade caused by depletion of the useable toner in the cartridge; or automatic printing stop caus
16、ed by a toner out detection function. This International Standard will be used for the measurement of one of the contributions to cost per page (CPP). This International Standard does not directly measure CPP, only the yield of the magenta, cyan, yellow and black toner cartridges. In most cases, the
17、se are not the only contributors to the CPP. It is beyond the scope of this document to provide a methodology for calculation of CPP. DIN ISO/IEC 19798:2014-11 5 1 Scope The scope of this International Standard is limited to evaluation of toner cartridge page yield for toner-containing cartridges (i
18、.e. all-in-one toner cartridges and toner cartridges without a photoconductor) for colour electrophotographic printers. 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
19、 contain electrophotographic printer components. This International Standard is only intended for the measurement of toner cartridge page yield when printing on plain paper using cyan, magenta, yellow and black toner cartridges. No other claims can be made from this testing regarding quality, reliab
20、ility, etc. This International Standard is not for use with printers whose minimum printable size is equal to or greater than A3 or for photo-only printers. NOTE Application of this International Standard for yield measurement of toner replenishment systems (i.e. toner cartridge and bottle type syst
21、ems where the toner reservoir is internal to the printing system and not user-replaceable) requires some procedural modifications specifically noted herein. This International Standard is intended for equipment used in the office space and does not apply to production volume or large format printing
22、 machines where the major cost of ownership is not caused by the consumable yield measured in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、round sides of the diagnostic page occurs NOTE 1 This does not have to be a distinct gap. NOTE 2 In this test, fade is defined as a noticeably lighter area, 3 mm or greater located in the bars around the diagnostic page of the test suite. Generally, the lightening will occur parallel to the paper mo
26、vement direction during printing. The determination of the change in lightness is to be made referenced to the 100th page (Diagnostic Page) printed for each cartridge in testing. For examples of fade, please consult Annex A. N1) National footnote: The word “or” is missing in the English reference ve

DIN ISO/IEC 19798:2014-11 6 3.2 shake procedure in the case that the cartridge users manual instructs cartridge shaking and its method, shaking the cartridge is performed according to the manual instructionsN2)NOTE If a shake procedure is used in testing it will be noted in the report. 3.3 to
28、ner low warning generated by the printing system when it has determined that the amount of toner is such that a cartridge change may be required soon NOTE It does not indicate that the system is out of toner. 3.4 toner out signal generated by the printing system when the useable toner in the system
29、is depleted and the printer will not continue printing without user intervention NOTE For the purpose of this test, the toner out signal will only be used if it causes the printer to stop printing. 3.5 end of life when the printer declares “toner out” or when fade is observed NOTE 1 The general inte
30、nt of this definition is to allow two shake procedures near end of life and to declare end of life at the first fade after the two shake procedures. Nominally, the shake procedures are to be executed at print fade. However, if the printer is equipped with a toner low device, then the first, second o
31、r both shake procedures can be executed at toner low instead of at fade as a convenience for the tester. If the cartridge users guide does not specify a shake procedure, then the shake procedures are not performed and end of life occurs at the first fade. Any faded pages printed during the test are
32、to be excluded from the cartridge page count. NOTE 2 If the printer is equipped with a toner out device, then end of life occurs when the printer declares toner out. However, when fade occurs before toner out and no shake procedure is specified, then end of life is declared at the fade. If a shake p
33、rocedure is specified for a printer with a toner out device, then up to two shake procedures can be executed as described in Note 1 when fade occurs before toner out. In this case, if fade occurs after two shake procedures but before toner out, then end of life is declared at the third fade. If tone
34、r out occurs at any time during testing, the cartridge is considered to be at end of life. NOTE 3 When applied to replenishment systems (bulk toner replacement or multi-part toner systems), the intent of this definition is to declare a quasi-end of cartridge life at a regular predetermined point. If
35、 the printer is equipped with a toner low or toner out signal, these can be used as the point of quasi-end of life. In either case, the end of life condition chosen must be noted in the test report. NOTE 4 When shake procedures have been performed during the test, the test report will note for both
36、the first and second shake procedures whether they were done at toner low or at fade. Any faded pages printed during the test are to be excluded from the cartridge page count. NOTE 5 Application of this definition may be clarified by reference to a flow chart and examples found in Annex B. 3.6 indiv
37、idual cartridge yield value determined by counting the number of diagnostic pages (page 5 of the ISO/IEC 24712 test suite) printed between cartridge installation and end of life (as defined in 3.5) and multiplying by 5 NOTE If the printer stops due to toner out in the middle of a test page suite, th
38、e number of the diagnostic pages printed is counted. Then, the first diagnostic page of the suspended print job is included in the subsequent cartridge yield. The number of test page suites counted may contain some pages that show visible fade. To simplify the testing, determination of end of life i
39、s only made on the diagnostic page (page 5). N2) National footnote: The original ISO document incorrectly specifies requirements here and not a definition. The text should read: “method used to redistribute the toner in the cartridge as described in the users manual”. DIN ISO/IEC 19798:2014-11 7 3.7
40、 declared cartridge yield value at or below the lower 90 % confidence bound as prescribed in 6.1 and 6.3 4 Test parameters and conditions 4.1 Set-up Place the printer on a horizontal surface and set-up the printer according to the installation guide provided in the printer users manual. Use the most
41、 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. Cartridge installation shall be completed following the instructions in the cartridge installation guide. If there is a contradiction betw
42、een the printer and cartridge manuals for the cartridge installation, the cartridge manual will take precedence except if changes are recommended for printer or driver settings. If the cartridges used in testing are toner replenishment or toner bottle types, then one set of toner cartridges will be
43、used to end of life in each printer before the start of the test. The pages printed to deplete these priming cartridges do not have to be recorded and printing can be conducted at any environment. The priming cartridges are used to bring the printing system to a set toner level condition. NOTE The c
44、artridges used to bring the printing system to a set toner level condition do not have to start out full. For large capacity systems, using a complete cartridge could result in tens of thousands of pages printed just to bring the system to a set condition. All image and print quality modifiers shall
45、 be at their factory pre-set configuration for the printer and default installed condition for the driver. If the printer and driver differ, then the driver defaults shall be used. Any user selectable toner conservation modes shall be disabled during testing. If auto media detection is available on
46、the printer, it shall be disabled and media-type set to plain paper. This is to avoid inaccurate sensing of the media. For printers that default to duplex printing, the default shall be overridden and the printer be set to simplex for yield testing. If the printer under test uses an internal PDF int
47、erpreter, it is ok to use it as long as the printer defaults are set to not substitute fonts. If the internal interpreter is used, this shall be noted on the report. To assure that the test page is printed correctly, any page size modifiers such as Fit to Page and font substitution shall be turned o
48、ff. If the option exists, rendering of graphics shall be performed by the printer, not the application software or operating system. The files shall be printed using the fonts embedded in the file and shall be printed on the page in a size corresponding to the dimensions in the test suite standard (
49、ISO/IEC 24712). Page placement modifiers such as page centering can be used to place the image properly on the page. If available, any colour management shall be set to the printer and driver installed defaults. If there is a question about rendering settings affecting the yield, the setting shall be noted in the report. NOTE The application software (i.e. Adobe ReaderN3), printer driver and printer may have page size modifier functions, such as “Fit to Page”. Make sure that all of t
