20、19752:2017(E)IntroductionThe purpose of this document is to provide a process for determining the page yield for toner cartridges for monochromatic print systems using a standard office consumer type test page. In the case where a cartridge can be used in multiple printer models, only one yield test

21、 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 one yield test is required as long as there are no differences in the cartridges othe

22、r 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 appropriate method of describing the yield of cartridges in documentation supplied t

23、o 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 toner out detection function.NOTE 2 A comparison of yield for two printing systems is show

25、 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 electrophotographic print systems. This document could also be applied to the printer component of any

26、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 claims can be made from this testing regarding quality, reliability, etc.NOTE 1 Applicatio

27、n 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 modifications specifically noted herein. This document is intended fo

28、r 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 cartridge is a cartridge that includes at least a toner containment pa

29、rt, a photoreceptor part and a developer part (see ISO/IEC 29142-1).2 Normative referencesThere are no normative references in this document.3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.ISO and IEC maintain terminological databases for use in st

35、oner out” (3.4) or when fade (3.1) is observedNote 1 to entry: For more information about the exact requirements for judging end of life, see 4.8.3.6individual page yieldnumber of “standard page file” pages printed between cartridge installation and end of life (3.5)Note 1 to entry: For replenishmen

36、t 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).3.7declared page yieldvalue at or below the lower 90 % confidence bound as prescribed in 6.14 Test parameters and condition

37、s4.1 Set-upPlace 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 manufacturer. The driver version will be specified on the test report. Cartridge installation sh

38、all 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 settings.If the car

39、tridge 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 pages printed to deplete this priming cartridge do not have to be recorded and printing can be conducted at any environment. This pri

40、ming 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 configuration for the printer and default installed condition for the driver. If the printer and driver differ, then the driver defaults shall be

41、 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 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 i

42、t 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 rendered correctly, any page size modifiers such as “Fit to Page”, “Page Centring” and font substitution shall be turned off. To f

43、urther 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 TrueType fonts if the driver provides that option. If the option exists, rendering of graphics shall be performed by the printer, not the appl

44、ication 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 the dimensions in the test page description. Page placement modifiers, such as page centring, may be used to place the image properly on t

45、he 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 ReaderTM1), printer driver and printer may have page size modifier functions, such as “Fit to Page”. Make sure that all of these functions

46、are disabled.4.2 Sample sizeA combination of at least three cartridges shall be run on a combination of at least three printers (for a minimum of nine cartridges and three printers). This is the minimum number of engines and cartridges that shall be used for testing. When feasible, it is recommended

47、 that additional engines and cartridges be used in testing. When testing additional engines and cartridges above the minimum, an effort should be made to test 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 t

48、ested would be 12 (3 cartridges 4 engines). When testing cartridges for a released product, it is recommended that cartridges and printers are procured from various sources, or selected from different production lots. The printers and cartridges shall be within their useful life as stated in their u

49、sers manual.It is recommended that an additional cartridge be procured to allow for the possibility of cartridge failure during testing.4.3 Print modeFor 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 replenishment, etc. Every attempt should be made to have printing be continuous from the start of a cartridge to the end of cartridge life. If the printer is powered down at the end of day duri
