Canon GI-21 Black Ink Bottle MegaTank Printers

The Canon GI-21 Pigment Black Ink Bottle is purpose-built for Canon's MegaTank printer line, delivering up to 6,000 pages of crisp black text from a single bottle. Unlike traditional cartridge systems that run out quickly and cost significantly per replacement, the MegaTank refill approach dramatically reduces the cost per printed page — making it an ideal solution for home offices, students, and small businesses that print documents frequently. The pigment-based formulation ensures that text is sharp, well-defined, and resistant to water smearing, which is particularly important for printed documents that may be handled or filed.

Refilling is designed to be completely hassle-free. The bottle features a precision-engineered nozzle that mates directly with the MegaTank printer's ink reservoir opening, allowing you to pour the ink in without drips, spills, or the need for any tools. This genuine Canon ink is formulated to work in harmony with the printer's internal components, helping to maintain consistent print quality and protect the printhead from the buildup and clogging that can occur with off-brand alternatives. Compatible models include the PIXMA G1220, G2260, G3260, G1230, G2270, G3270, G4270, G3290, and G4280.
