The CLI-251Y Standard Capacity Yellow Ink Tank from Canon
is part of the ChromaLife100+ system that guarantees print longevity of
300 years when used with select Canon paper and stored in an
archival-quality photo album. The tank features an LED light which will
illuminate when you install the ink tank correctly. Additionally, when a
full set of Canon ink tanks is installed, you can access content on
Canon's Creative Park Premium website for free.
