Frequently Asked Questions
How does colour depletion work in the BCI-21 tri-colour cartridge?
The BCI-21 Colour cartridge contains cyan, magenta and yellow ink in a single housing. If one primary colour runs out during heavy use of specific tones, the entire colour cartridge must be replaced to restore complete colour balance.
Can I replace the BCI-21 Black cartridge independently of the colour cartridge?
Yes, the Canon BJC-4550 uses separate printhead carriage slots for the BCI-21 Black and BCI-21 Colour cartridges, allowing you to replace the black ink tank whenever it empties without disturbing the colour tank.
How should unopened BCI-21 cartridges be stored to maintain performance?
Store sealed BCI-21 cartridges upright in a cool, dark environment away from direct heat sources. Keeping them sealed in their original packaging prevents the internal sponge material from drying out before installation.
