Canon GI-21 Ink Bottles

Everything this family needs is on one page. The GI-21 range fits 11 Canon printers and consists of GI-21 Black (170 ml, about 6,000 pages), GI-21 Cyan (70 ml, about 7,700 pages), GI-21 Magenta (70 ml, about 7,700 pages), GI-21 Yellow (70 ml, about 7,700 pages). Each Clever Supplies version matches the original fill and specification and carries a lifetime warranty.

The GI-21 bottles cover the widest MegaTank range Canon sells — eleven PIXMA G models from the G1220 up to the G4280. The pigment black bottle and three dye color bottles are keyed to their tanks, and a set is rated at 6,000 black and 7,700 color pages.

Which GI-21 should you buy?

Compatible Canon GI-21 Black Ink Bottle — $19.49 — usually the first tank to run low.
Compatible Canon GI-21 Cyan Ink Bottle — $14.99 — refills only the cyan tank, a 70 ml dye color bottle.
Compatible Canon GI-21 Magenta Ink Bottle — $14.99 — refills only the magenta tank, at 70 ml like the other GI-21 colors.
Compatible Canon GI-21 Yellow Ink Bottle — $14.99 — refills only the yellow tank when its level is low.
Compatible Canon GI-21 Set of 4 BCMY Ink Bottles — $53.94 — best value if you print in volume or want every slot covered.
Compatible Canon GI-21 Set of 10 4 Black 2 Cyan 2 Magenta 2 Yellow Ink Bottles — $127.35 — the ten-bottle stock-up, with 4 black and 2 of each color for volume printing.

Refilling and everyday use

Across eleven PIXMA G models, the GI-21 habit that saves money is timing: refill before a tank runs completely dry, while the choice is still a single bottle. Keep the printer on a level surface so the level readings stay honest, and print regularly enough that ink keeps moving through the head. Bottles store capped and upright for the next refill, and a bottle that ever leaks or under-fills is covered by the lifetime warranty.
