What Ink Does the Canon PIXMA MG6120 Use?

Last updated: September 25, 2026.

Quick answer: The Canon PIXMA MG6120 uses six ink tanks: PGI-225 pigment black plus CLI-226 black, gray, cyan, magenta and yellow. Castle Ink’s remanufactured PGI-225 black is $9.95 and each CLI-226 color is $8.95, so a full set costs about $55.

What Ink Cartridges Does the Canon PIXMA MG6120 Use?

Yields are the manufacturer's ISO estimates at about 5% coverage; photos and heavy graphics use more ink. Castle Ink prices checked September 2026.

Which Printers Use the Same Ink as the MG6120?

PGI-225/CLI-226 tanks also fit the PIXMA MG5120, MG5220, MG5320, MG6220, MG8120 and MG8220, the iP4820 and iP4920, the iX6520, and the MX882 and MX892. Five-ink models in this family don’t use the gray tank. Look up any model in our find ink by printer directory.

What Is the Cheapest Ink for the MG6120?

Remanufactured PGI-225/CLI-226 tanks are the cheapest option by far. Canon’s originals typically cost around $15–$20 per tank at retail, so a six-tank set can top $100. Castle Ink’s tanks are $8.95–$9.95 each, and because each color is separate, you only replace the one that runs out. For heavy users, the 12-pack brings the per-tank price down further.

Why Does the MG6120 Have Two Black Inks and a Gray?

The PGI-225 pigment black gives sharp, smudge-resistant text on plain paper. The CLI-226 dye black blends with the colors for photos, and the CLI-226 gray improves neutral tones and black-and-white photos. The printer uses all six, so replace each when it runs low.

How Do I Replace the Ink in the Canon PIXMA MG6120?

1. Turn the printer on and open the scanner unit/cover; the print head holder moves to the replacement position.
2. Press the tab on the empty ink tank and lift it out.
3. Remove the new tank from its packaging, then twist or pull off the orange protective cap (and any film).
4. Insert the tank into its matching color slot and press the PUSH mark until it clicks. The tank's lamp should light red.
5. Close the cover. If prompted about a non-genuine or refilled cartridge, confirm to continue.

Will Remanufactured Ink Work in the MG6120?

Yes. Canon PIXMA printers are generally friendly to third-party cartridges. You may see a message that a non-genuine or refilled cartridge is installed, or that the ink level can't be detected; confirm to continue printing, and keep a spare of the colors you use most since levels may not display. Using third-party ink does not void your warranty (here's why).

Why Does My MG6120 Say the Cartridge Isn't Recognized?

Remove the cartridge, make sure all protective tape and caps are off, wipe the chip or copper contacts gently with a dry lint-free cloth, and reinstall until it clicks. Confirm the part number matches this printer, then restart. If the message started right after a firmware update, the update may be blocking third-party chips. Full steps: ink cartridge not recognized.

How Do I Fix Streaky or Faded Prints on the MG6120?

From the printer's Setup/Maintenance menu (or the Canon IJ utility on your computer), print a nozzle check, then run one Cleaning cycle and check again; use Deep Cleaning only if needed. See how to clean Canon printer heads.

What Are the Canon PIXMA MG6120's Key Features?

The PIXMA MG6120 is a six-ink wireless photo all-in-one (print, scan, copy) with automatic two-sided printing, a touch-sensitive control panel, a CD/DVD printing tray, and Wi-Fi.

Is the MG6120 Still Worth Using in 2026?

Yes, if it still prints well. The MG6120 is discontinued, but PGI-225/CLI-226 tanks remain inexpensive. Its print head is separate from the ink tanks, so if cleaning can’t fix missing colors, the head may need replacing, which usually costs more than a new printer.
