The Canon PFI-031M is a magenta ink tank designed for use in large format inkjet printers, specifically the imagePROGRAF TM-240 and TM-340 models. It utilizes LUCIA TD pigment-based ink, which allows you to produce sharp, smudge-resistant prints that maintain their clarity on various media types. Each cartridge contains 55 ml of ink and is manufactured in Japan to ensure consistent performance. This makes it a reliable choice for professionals who need to print high-quality technical drawings or posters where color precision and durability are essential.
