What Ink Cartridge for Brother MFC-J4420DW?

by William Elward Last Updated:

Quick answer: The Brother MFC-J4420DW uses Brother LC101 standard-yield or LC103 high-yield ink cartridges. You'll need four individual cartridges: Black (LC103BK), Cyan (LC103C), Magenta (LC103M), and Yellow (LC103Y).

LC101 vs. LC103: What's the Difference?

LC101 cartridges are the standard-yield version (~300 pages) while LC103 are the XL high-yield version (~600 pages). Both work in the MFC-J4420DW — LC103 simply delivers roughly 2× the pages at only a small additional cost.

  • LC101BK — Standard Black (~300 pages)
  • LC103BK — High-Yield Black (~600 pages)
  • LC101 / LC103 color set — C, M, Y in standard or XL

How to Install LC103 Cartridges

  1. Turn on the MFC-J4420DW and lift the scanner cover until it locks in the up position.
  2. Push the lock release of the empty cartridge and pull it up and out.
  3. Remove the orange protective cap from the new LC103 cartridge.
  4. Drop the cartridge into the matching color slot.
  5. Close the scanner cover gently — priming begins automatically.

Stop Wasting Money on OEM

OEM LC103 cartridges run $25–$30 each; a full 4-pack from Brother can cost over $100. Compatible LC103 cartridges from Castle Ink's Brother ink collection deliver the same print quality at a fraction of the price, with free U.S. shipping on orders over $50.

Troubleshooting Tips

If your printer displays "Unable to Detect" after installing a new cartridge, remove it, wipe the copper contact with a dry microfiber cloth, and reinsert. If the error persists, reboot the printer. More error codes are covered on the official Brother MFC-J4420DW support page.
