1 Scope
The 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 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 devices 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, 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 1Application 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 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 cartridge is a cartridge that includes at least: a toner containment part, a photoreceptor part and a developer part (see ISO/IEC 29142-1).
3.6 individual cartridge yield
value determined by counting the number of diagnostic pages (page 5 of the ISO/IEC 24712 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 print 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 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 user's manual. Use the most recent printer driver available from the manufacturer's 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 the cartridge installation, the cartridge manual will take precedence except if changes are recommended for printer or driver settings.ISO IEC 19798 pdf download.
