The Canon GI-40 is a magenta pigment-based ink bottle designed to keep your printer running smoothly for long periods. With a volume of 70ml, this Japanese-made ink allows you to print up to 7,700 pages, making it a practical choice for those who handle high printing volumes without wanting to replace cartridges frequently. This specific magenta ink is compatible with several PIXMA models, including the G5040, G6040, and G7040, as well as the GM2040 and GM4040. To make the refilling process cleaner and easier for you, the bottle features a no-squeeze design with a hinged cap that helps prevent spills while you top up your printer's tanks.
