Canon BJC-4300 BJC-4310 Ink Cartridges
Your Canon BJC-4300 and BJC-4310 printers use the BCI-21 ink cartridge series. Designed for everyday home document and light colour printing, these classic Bubble Jet printers rely on a dual-cartridge system. Replacing the BCI-21 Black ink tank separately from the BCI-21 Colour tank prevents unnecessary ink waste during text-heavy print runs. Ink Depot has been supplying reliable consumables for these printers since Aug 2026. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected page output and replacement cycles
Page yields for BCI-21 ink cartridges are measured using ISO/IEC standard test pages under standard operating conditions. Actual output varies based on text coverage, document type, and print frequency. Because black ink depletes faster during regular text printing, replacing individual tanks as needed keeps ongoing printing costs low.
Choosing compatible BCI-21 cartridges
Our premium compatible BCI-21 ink cartridges deliver clear text output and vibrant colours while significantly reducing your running expenses. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Read our comprehensive genuine vs compatible cartridge guide to learn more about how quality compatible supplies perform in legacy printers.
Best way to stock BCI-21 cartridges
If you print mostly text documents, stocking up on BCI-21 Black multipacks ensures uninterrupted workflow. For mixed colour graphics, keeping spare BCI-21 Colour cartridges on hand prevents sudden downtime. All compatible cartridges come backed by a money-back guarantee if they do not work under our returns policy.

Pro Tip
Always store uninstalled BCI-21 ink cartridges in an upright position at room temperature inside their sealed protective packaging until ready for installation to prevent printhead nozzle clogging.
Frequently Asked Questions
Do the Canon BJC-4300 and BJC-4310 use the same ink cartridges?
Yes. Both the BJC-4300 and BJC-4310 belong to the same printer family and use identical BCI-21 Black and BCI-21 Colour ink cartridges.
Can I install a BCI-21 Colour cartridge without a Black cartridge installed?
No. The printhead carriage requires both the BCI-21 Black and BCI-21 Colour cartridge seats to be populated to complete the circuit and allow printing.
Why does my colour output look faded even when ink levels are sufficient?
On legacy inkjet models, infrequent printing can cause micro-droplets of ink to dry at the cartridge nozzles. Installing a fresh cartridge or running a cleaning cycle via your printer driver restores proper ink flow.
How do I know whether to replace the BCI-21 Black or Colour cartridge?
Your computer print status monitor will flag which specific chamber is low. Text documents rely solely on the BCI-21 Black cartridge, while graphics and mixed documents draw from both tanks.
