The Canon PFI-706 is a high-capacity blue ink cartridge designed for professional wide-format printing. With a pack size of 700 ml and a cartridge capacity tier of 700 ml, it provides the stability and durability needed for technical drawings and high-quality graphics that resist fading over time. This tank is specifically engineered for use with the imagePROGRAF series, including the iPF8300, iPF8400, iPF9400, and iPF9400S models. Its large volume reduces the frequency of replacements, making it a practical choice for users who handle high-volume print jobs in an office or studio environment.
