Canon BJC-4000 BJC-4100 Ink Cartridges
Your Canon BJC-4000 and BJC-4100 printers use BCI-21 ink cartridges, reliable desktop Bubble Jet models built for light home document printing. Ink Depot has been supplying quality consumables for these printers since Aug 2026. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance. Replacing the BCI-21 Black cartridge separately from the BCI-21 Colour tank helps manage printing costs by only renewing black ink when standard text documents drain it.
Expected page output and replacement cycles
BCI-21 cartridge page yields are evaluated based on standard ISO/IEC coverage testing for inkjet printing. Actual page yield varies depending on document coverage, paper type, and printing frequency.
Choosing compatible BCI-21 cartridges
Compatible BCI-21 cartridges offer an economical solution for everyday document printing. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Learn more about how compatible cartridges perform in our genuine vs compatible guide.
Selecting the right BCI-21 cartridge setup
For standard black text documents, ordering individual BCI-21 Black cartridges or multi-packs offers maximum value. If your printing includes occasional graphics or charts, keeping a spare BCI-21 Colour cartridge on hand prevents unexpected delays. Compatible items come backed by our money back guarantee if they do not perform as expected. Review our full Returns policy for complete confidence.

Cartridge selection tip
Always leave the BCI-21 Black and Colour printhead tanks properly seated during cartridge changes, as removing empty cartridges without immediate replacement can cause remaining printhead nozzles to dry out.
Frequently Asked Questions
Do the Canon BJC-4000 and BJC-4100 use the exact same ink cartridges?
Yes, both the BJC-4000 and BJC-4100 use the same BCI-21 ink cartridge series, making BCI-21 Black and Colour cartridges fully interchangeable between both printer models.
Can I install a BCI-21 Black cartridge without replacing the BCI-21 Colour cartridge?
Yes, the BCI-21 system uses separate black and colour cartridges, allowing you to replace the BCI-21 Black tank independently whenever black ink runs out.
Why does my BCI-21 Colour cartridge run out even when I mostly print black text?
Certain print settings utilise small amounts of cyan, magenta, and yellow ink from the BCI-21 Colour cartridge to create composite grey tones or maintain printhead hydration.
What should I do if a compatible BCI-21 cartridge is not recognised?
Ensure the cartridge protective clip is completely removed before insertion, then gently reseat the BCI-21 tank into the printhead carriage to establish clean contact points.
