In the
21、 case where a cartridge can be used in multiple printer models, only one yield test is performed as long as the difference between printer models does not impact yield. NOTE 1 A cartridge supplier can choose to use more than one market identifier for a single physical cartridge. In this case, only o
22、ne 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 use to determine cartridge yield; the method for determination of declared yield values from the test results; the
23、 appropriate method of describing the yield of cartridges in documentation supplied to the consumer by the manufacturer. The end of life is judged with either of the two phenomena, “image fade” caused by toner depletion of the cartridge in the printing system or “automatic printing stop” by the tone
24、r out detection function. NOTE 2 A comparison of yield for two printing systems is shown in Annex E.

25、ographic printers and multi- function devices that contain printer components 1 Scope This document is limited to the evaluation of toner cartridge page yield for toner containing cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) for monochrome electrophotog
26、raphic print systems. This document could also be applied to the printer component of any multifunctional device that has a digital input-printing path (i.e. multi-function devices that contain printer components). This document is only intended for the measurement of toner cartridge yield. No other
27、 claims can be made from this testing regarding quality, reliability, etc. 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) r
28、equires 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 is not caused by the consumable yield measured in this documen
29、t. NOTE 2 An all-in-one 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 There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the
30、 following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at h t t p :/ www .electropedia .org/ ISO Online browsing platform: available at h t t p :/ www .iso .org/ obp 3.1 fade phenomenon
31、whereby a noticeable reduction in density uniformity across the page occurs Note 1 to entry: In this test, fade is defined as a noticeably lighter, 3 mm or greater, gap located in the text or boxes around the periphery of the test page. The determination of the change in lightness is to be made refe
32、renced to the 100th page printed for each cartridge in testing. For examples of fade, see Annex A. 3.2 shake procedure specified method to carry out shaking of a 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.

34、hat 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 it causes the pr
35、inter 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 Note 1 to entry: For more information about the exact requirements for judging end of life, see 4.8. 3.6 individual page yield number
36、 of “standard page file” pages printed between cartridge installation and end of life (3.5) Note 1 to entry: For replenishment systems, the individual page yield is determined by counting the number of “standard page file” pages printed between prescribed quasi-end of life conditions (defined in 4.5
37、). 3.7 declared page yield value at or below the lower 90 % confidence bound as prescribed in 6.1 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
38、 printer driver available from the manufacturer. 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 the cartridge
39、installation, the cartridge manual will take precedence except if changes are recommended for printer or driver settings. If the cartridge used in testing is a toner replenishment or toner bottle type, then one complete toner cartridge will be used in each printer before the start of the test. The p
40、ages printed to deplete this priming cartridge do not have to be recorded and printing can be conducted at any environment. This priming cartridge is used to bring the printing system to a set toner level condition. All image and print quality modifiers shall be at their factory pre-set configuratio
41、n 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. For printers that default to duplex printing, the default shall be overridden and
42、 the printer shall 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 pa
43、ge is rendered correctly, any page size modifiers such as “Fit to Page”, “Page Centring” and font substitution shall be turned off. To further ensure that font substitution does not 2 ISO/IEC 2017 All rights reservedBS ISO/IEC 19752:2017ISO/IEC 19752:2017(E) occur, fonts shall be downloaded as TrueT
44、ype fonts if the driver provides that option. If the option exists, rendering of graphics shall be performed by the printer, not the application software or operating system. The file shall be printed using the fonts embedded in the file and shall be rendered on the page in a size corresponding to t
45、he dimensions in the test page description. Page placement modifiers, such as page centring, may be used to place the image properly on the page. 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 R
46、eader TM 1) ), printer driver and printer may have page size modifier functions, such as “Fit to Page”. Make sure that all of these functions are disabled. 4.2 Sample size A combination of at least three cartridges shall be run on a combination of at least three printers (for a minimum of nine cartr
47、idges and three printers). This is the minimum number of engines and cartridges that shall be used for testing. When feasible, it is recommended that additional engines and cartridges be used in testing. When testing additional engines and cartridges above the minimum, an effort should be made to te
48、st equal number of cartridges on each engine. For example, if an additional engine is to be tested then the minimum number of cartridges to be tested would be 12 (3 cartridges 4 engines). When testing cartridges for a released product, it is recommended that cartridges and printers are procured from
49、 various sources, or selected from different production lots. The printers and cartridges shall be within their useful life as stated in their users manual. It is recommended that an additional cartridge be procured to allow for the possibility of cartridge failure during testing. 4.3 Print mode For reporting cartridge yield, the test shall be run in semi-continuous print mode simplex printing. The actual print speed will be semi-continuous because of printing being interrupted for paper
