The scope of this International Standard is limited to evaluation of toner cartridge page yield for tonercontaining
cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) for colour
electro-photographic printers. This International Standard 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
electro-photographic printer components.
This International Standard 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 International Standard is not for use with printers whose minimum printable size is equal to or greater
than A3 or for photo only printers.
NOTE Application of this International Standard 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 International Standard 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 International Standard.
