21、cument is to provide a process for determining the cartridge page yield for a given 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
22、 photographs, but is intended to be a sampling of typical office consumer pages. 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 can c
23、hoose to 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 document prescribes the following: the test method that manufacturers, test labs, etc.
24、 use to determine cartridge yield; the method for determination of declared yield values 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
25、, or signalled with either of two phenomena: fade caused by depletion of the useable 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 d
26、irectly measure CPP, only the yield of the magenta, cyan, yellow and black toner cartridges. 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. ISO/IEC 2017 All rights reserved vBS ISO/IEC 19798:2017
27、BS ISO/IEC 19798:2017Information technology Office equipment Method for the determination of toner cartridge yield for colour printers and multi-function devices that contain printer components 1 Scope The scope of this document is limited to evaluation of toner cartridge page yield for toner-contai
28、ning cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) 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 dev
29、ices that contain electrophotographic printer components. This document 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, reliability
30、, etc. This document is not for use with printers whose minimum printable size is equal to 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 i
31、s internal to the printing system and not user- replaceable) requires some procedural modifications 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
32、is not caused by the consumable yield measured in this document. NOTE 2 An all-in-one toner cartridge 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 references The following documents are referred to in th

Generally, the lightening will occur para
37、llel to the paper movement 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, consult Annex A. 3.2 shake procedure specified method to carry out shaking of a
38、 cartridge according to the user manual Note 1 to entry: If a shake procedure is used in testing, it will be noted in the report. 3.3 toner low signal generated by the printer when it has been detected that the amount of toner is such that a toner change will be required soon Note 1 to entry: It doe
39、s not indicate that the system is out of toner. 3.4 toner out signal generated by the printer when the toner in the system is depleted and the printer is incapable of reliable printing without user intervention Note 1 to entry: For the purpose of this test, the toner out signal will only be used if
40、it causes the printer to stop printing and requires toner replacement to continue printing. 3.5 end of life when the printer declares “toner out” (3.4) or when fade (3.1) is observed 3.6 individual cartridge yield value determined by counting the number of diagnostic pages (page 5 of the ISO/IEC 247
41、12 test suite) printed between cartridge installation and end of life (3.5) and multiplying by 5 Note 1 to entry: If the printer 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 pr
42、int job is included in the subsequent cartridge yield. The number of test page suites counted may contain some pages that show visible fade (3.1). To simplify the testing, determination of end of life (3.5) is only made on the diagnostic page (page 5). 3.7 declared cartridge yield value at or below
43、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 recent printer driver available from the ma
44、nufacturers 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 between the printer and cartridge manuals for th
45、e 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 used to end of life in each printer before t
46、he start of the test.

The priming cartridges are used to bring the printing system to a set
47、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 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 imag
48、e and print quality modifiers shall 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 au
49、to media detection is available on 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 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
