The service life of a cartridge is 2.5 years from the date of manufacture, indicated by
means of an abbreviation on the cartridges.
For the user, a "service life," obtained by adding 2.5 years to the date of manufacture,
is indicated on the package and the cartridge itself.
Prints made using a cartridge older than its service life may have low image quality,
making it important to use up each cartridge before the end of its service life.
