National bodies that are members of ISO or IEC participate in the development of I

13、nternational 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. Other international organizations, governmental and non-governmental, in lia

In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part

15、 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is drawn to the possibility that some of the

21、n colour electrophotographic print system (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 intended to be a sampling of typical office consumer pages. I

22、n 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 can choose to use more than one market identifier for a single physical cartridge. In th

23、is case, only one yield test is required as long as there are no differences in the cartridges other than market identifiers.This document prescribes the following: the test method that manufacturers, test labs, etc. use to determine cartridge yield; the method for determination of declared yield va

24、lues from the test results; the appropriate method of describing the yield of cartridges in the 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

25、toner in the cartridge or automatic printing stop caused by a toner out detection function.This document will be used for the measurement of one of the contributions to cost per page (CPP). This document does not directly measure CPP, only the yield of the magenta, cyan, yellow and black toner cartr

26、idges. In most cases, these are not the only contributors to the CPP. It is beyond the scope of this document to provide a methodology for calculation of CPP.

27、ion of toner cartridge yield for colour printers and multi-function devices that contain printer components1 ScopeThe scope of this document is limited to evaluation of toner cartridge page yield for toner-containing cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoco

28、nductor) for colour electrophotographic print systems. This document 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 electrophotographic printer components.This document is only intended

29、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, reliability, etc.This document is not for use with printers whose minimum printable size is equal to

30、 or greater than A3 or for photo-only printers.NOTE 1 Application of this document for yield measurement of toner replenishment systems (i.e. toner cartridge and bottle type systems where the toner reservoir is internal to the printing system and not user-replaceable) requires some procedural modifi

31、cations specifically noted herein. This document is intended for equipment used in the office space and does not apply to production volume or large format printing machines where the major cost of ownership is not caused by the consumable yield measured in this document.NOTE 2 An all-in-one toner c

32、artridge is a cartridge that includes at least: a toner containment part, a photoreceptor part and a developer part (see ISO/IEC 29142-1).2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this documen

36、to entry: 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 movement direction during printing. The determination of the change in lightness is to b

41、ter stops due to toner out (3.4) in the middle of a test page suite, the 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 sho

To simplify the testing, determination of end of life (3.5) is only made on the diagnostic page (page 5).3.7declared cartridge yieldvalue at or below the lower 90 % confidence bound as prescribed in 6.1 and 6.34 Test parameters and conditions4.1 Set-upPlace the printer on a hor

43、izontal 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. Cartridge ins

44、tallation 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 driver setting

45、s.If the cartridges used in testing are toner replenishment or toner bottle types, then one set of toner cartridges will be used to end of life in each printer before the start of the test.

46、 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 1 The cartridges used to bring the printing system to a set toner level condition do not have to start out

47、 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 be at their factory pre-set configuration for the printer and default installed condition for the d

48、river. 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 the printer, it shall be disabled and media-type set to plain paper. This is to avoid inaccurate sen

49、sing 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 interpreter, it is okay 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 off.
