12、test page. This standard prescribes the following: The test method that manufacturers should 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 to the co
13、nsumer by the manufacturer. The end of life is judged with either of 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. 5Information technology Method for the determination of toner cartridg
14、e yield for monochromatic electrophotographic printers and multi-function devices that contain printer components DIN ISO/IEC 19752:2015-05 1 Scope The scope of this International Standard is limited to evaluation of toner cartridge yield for toner containing cartridges (i.e. all-in-one toner cartri
15、dges and toner cartridges without a photoconductor) for monochrome electrophotographic printers. This International Standard 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 component
16、s). This International Standard is only intended for the measurement of toner cartridge yield. No other claims can be made from this testing regarding quality, reliability, etc. NOTE Application of this International Standard for yield measurement of toner replenishment systems (i.e. toner cartridge
17、- 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 International Standard is intended for equipment used in the office space and does not apply to production volume or
18、 large format printing machines where the major cost of ownership is not caused by the consumable yield measured in this International Standard. 2 Terms and definitions For the purposes of ISO 19752, the following terms and definitions apply. 2.1 Fade a phenomenon whereby a noticeable reduction in d
19、ensity uniformity across the page occurs NOTE 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 referenced to the 100th page printed for each cartr
20、idge in testing. For examples of fade, please consult Annex A. 2.2 Shake Procedure in the case that the cartridge users manual instructs cartridge shaking and its method, shaking the cartridge according to the procedures specified NOTE If a shake procedure is used in testing it will be noted in the
21、report. 2.3 Toner Low a 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 It does not indicate that the system is out of toner. 6DIN ISO/IEC 19752:2015-05 2.4 Toner Out a signal generated by the printer when the
22、toner in the system is depleted and the printer is incapable of reliable 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 and requires toner replacement to continue printing. 2.5 End of Life when th
23、e printer declares “Toner Out” NOTE 1 The general intent of this definition is to allow 2 shake procedures near end of life and to declare end of life at the first fade after the 2 shake procedures. Nominally the shake procedures are to be executed at print fade. However, if the printer is equipped
24、with a Toner Low device, then the first, second or both shake procedures can be executed at Toner Low instead of at fade as a convenience for the tester. If the users guide does not specify a shake procedure then the shake procedures are not done and end of life occurs at the first fade. NOTE 2 When
25、 fade occurs before Toner Out and no shake procedure is specified, then end of life is declared at the fade. If a shake procedure is specified for a printer with a Toner Out device, then up to 2 shake procedures can be executed as described in the paragraph above when fade occurs before Toner Out. I
26、n this case, if fade occurs after 2 shake procedures but before Toner Out, then end of life is declared at the third fade. If Toner 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-p
27、art toner systems), the intent of this definition is to declare a quasi-end of cartridge life at a regular predetermined point. If 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
28、be noted in the test report. NOTE 4 When shake procedures have been performed during the test, the test report will note for both 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 c
29、ount. NOTE 5 Application of this definition may be clarified by reference to a flow chart and examples found in Annex B. 2.6 Individual Page Yield the number of “standard page file” pages printed between cartridge installation and end of life (as defined in Section 3.5) NOTE For replenishment system
30、s, 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 Section 3.5). 2.7 Declared Page Yield (see Clause 6 ) 3 Test Parameters and Conditions 3.1 Set-up Place the printer on a horizontal surf
31、ace 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 shall be completed following the instructions in th
32、e 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 cartridge used in testing is a toner replenishment
33、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 7N1)N1) National footnote: The reference to Clause 6 is incorrect. It should refer to Clause 5. DIN ISO/IEC 19752:2015-05 not have
34、 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 should be at their factory pre-set configuration for the printer and default installed condition for the
35、 driver. If the printer and driver differ, then the driver defaults should be used. Any user selectable toner conservation modes should be disabled during testing. If the printer under test uses an internal PDF interpreter, it is ok to use it as long as the printer defaults are set to not substitute
36、 fonts. If the internal interpreter is used, this should 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 should be turned off. To further insure that font substitution does not occur, fon
37、ts should be downloaded as TrueType fonts if the driver provides that option. If the option exists, rendering of graphics should be performed by the printer, not the application software or operating system. The file should be printed using the fonts embedded in the file and should be rendered on th
38、e page in a size corresponding to the dimensions in the test page description. Page placement modifies such as page centering can be used to place the image properly on the page. If there is a question about rendering settings affecting the yield, the setting should be noted in the report. NOTE The
39、application software (i.e. Adobe Reader ), printer driver and printer may have page size modifierfunction s, such as “Fit to Page”. Make sure that all of these functions are disabled. 3.2 Sample Size A combination of at least three cartridges shall be run on a combination of at least three printers
40、(for a minimum of nine cartridges and three printers). This is the minimum number of engines and cartridges that should 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
41、 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 tested would be 12 (3 cartridges X 4 engines). When testing cartridges for a released product, it is recommended that cartridges
42、and printers are procured from various sources, or selected from different production lots. The printers and cartridges must be within their useful life as stated in their users manual. NOTE It is recommended that an additional cartridge be procured to allow for the possibility of cartridge failure
43、during testing. 3.3 Print Mode For reporting cartridge yield, the test shall be run in continuous print mode simplex printing, with printed output occurring at or near rated printer speed. The actual print speed will be semi-continuous because of printing being interrupted for paper replenishment et
44、c. Every attempt should be made to have printing be continuous from the start of a cartridge to the end of cartridge life. 3.4 Print Environment The temperature and humidity can have a profound effect on test results. For this reason, the test must be carried out according to the following test cond
45、itions: Temperature: Testing room average 23.0C 2C Readings to be made with a running average of 1 hour with readings recorded at least every 15 minutes, all running average temperatures are to be between 20.0C and 26.0C. Relative Humidity: Testing room average 50% 10% RH Readings to be made with a
46、running average of 1 hour with readings recorded at least every 15 minutes, all running average RHs are to be between 35% and 65%. P For printers that default to duplex printing, the default shall be overridden and the printer be set to for yield testing. Q simplexN2) National footnote: Adobe PDF Re

These values can be found highlighted in the table of temperature measurements. It should be noted that the testing room average for both temperature and RH are averages of all measurements, not the running averages. Prior to testing, the printer, paper and cartridges should be acclimated to the above conditions for a minimum of 8 hours
