The CLI-251M XL High-Capacity Magenta 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 ink tank features an LED light which
will illuminate when you install the ink tank correctly. Additionally,
when a full set of Canon ink is installed, you can access content on
Canon's Creative Park Premium website for free.
