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 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) 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.
