Canon GI-23 Ink Bottles

For the 1 Canon printer in the GI-23 family, the full Clever Supplies range is: GI-23 Black (57 ml), GI-23 Cyan (57 ml), GI-23 Magenta (57 ml), GI-23 Yellow (57 ml), GI-23 Red (57 ml), GI-23 Gray (57 ml). All of them are built to the original specification and backed by a lifetime warranty.

The GI-23 bottles exist for exactly one printer: the PIXMA G620 photo MegaTank. Six dye inks — the usual four plus Red and Gray — are tuned for photographs rather than documents, and Canon rates a full set at about 3,800 4×6 photos.

Which GI-23 should you buy?

Compatible Canon GI-23 Black Ink Bottle — $7.43 — usually the first tank to run low.
Compatible Canon GI-23 Cyan Ink Bottle — $7.43 — refills only the cyan tank, one 57 ml dye bottle for photo color.
Compatible Canon GI-23 Magenta Ink Bottle — $7.43 — refills only the magenta tank, at the same 57 ml fill as every GI-23 bottle.
Compatible Canon GI-23 Yellow Ink Bottle — $7.43 — refills only the yellow tank when that photo color runs low.
Compatible Canon GI-23 Red Ink Bottle — $7.43 — refills only the red tank, the extra color that stretches the photo gamut.
Compatible Canon GI-23 Gray Ink Bottle — $7.43 — refills only the gray tank, the extra bottle for neutral photo tones.
Compatible Canon GI-23 Set of 6 Ink Bottles — $35.55 — best value if you print in volume or want every slot covered.

Refilling and everyday use

Photo printing on the G620 — the only GI-23 printer — makes the right bottle worth checking twice: six dye inks, Red and Gray among them, each have their own formulation. Each bottle fits only its own tank, so topping up is hard to get wrong: uncap the tank, seat the bottle, wait for the level line, done. Do not mix colors or top a tank with a different GI family. If a refill leaves the level sensor confused, run the printer's ink flush or level reset from its maintenance menu.
