Lucia+Shelf+Life

=What is the shelf life of the Canon Lucia inks? How long are they good after installation in the printer?=

The shelf life of the Canon Lucia inks used in the IPF5000 is 18 months, according to the expiration date which should be on the package of each ink cartridge. The Service Manual states that the inks should be replaced 6 months after they are installed. However, many people have had cartridges installed for a year without any noticeable change in quality.
