Canon GI-21 Magenta Ink Bottle for MegaTank Printers

The Canon GI-21 Magenta Ink Bottle is a genuine Canon consumable engineered specifically for the company's MegaTank line of refillable ink tank printers. Unlike traditional cartridge-based systems, MegaTank printers use built-in reservoirs that you fill directly from ink bottles like the GI-21, dramatically lowering your cost per page. With a yield of up to 7,700 pages from a single magenta bottle, this ink supply is designed to keep you printing for months — or even longer — depending on your volume, making it an ideal solution for home offices, students, and small businesses that need reliable color output without the recurring expense of frequent cartridge replacements.

Canon's specialized nozzle design on the GI-21 bottle takes the anxiety out of refilling. The nozzle is shaped to fit the MegaTank ink reservoir opening precisely, allowing you to pour ink smoothly and cleanly without drips or spills. As a genuine Canon product, the GI-21's ink formulation is calibrated to work in harmony with compatible MegaTank models — including the G1220, G2260, G3260, G1230, G2270, G3270, G4270, G3290, and G4280 — ensuring accurate magenta color reproduction, sharp print detail, and consistent results page after page. For users who depend on reliable color output across documents, photos, and graphics, sticking with genuine Canon ink helps maintain the print quality and printer performance that the MegaTank system was designed to deliver.
