Canon PIXMA MX726 Ink Cartridges
The Canon PIXMA MX726 office all-in-one utilises a sophisticated five-tank ink system, featuring a dedicated pigment black for text and four dye-based cartridges for vibrant images. We have been supplying high-performance consumables for this versatile device since Nov 2013, helping home offices maintain professional output. Our 4.8 Google rating reflects our commitment to reliability and quality. This system is designed for efficiency; because each PGI-650 and CLI-651 colour tank is separate, you only ever replace the individual unit that has run out.
Understanding the Five-Tank System
The MX726 is unique because it uses two different types of black ink. The larger PGI-650 tank contains pigment-based ink specifically for crisp, smudge-resistant document printing. Meanwhile, the smaller CLI-651 black tank is used alongside the cyan, magenta, and yellow colours to provide deep contrast and smooth gradations in photo prints. Selecting the right size—whether standard, XL, or the high-capacity XXL black—allows you to tailor your ink supply to your monthly volume.

Pro Tip
If your MX726 is producing faint lines or inaccurate colours, the individual ink tanks feature a built-in LED. A flashing light usually indicates the ink is running low, while a rapid flash suggests the tank is empty. If the light is off entirely, the cartridge may not be seated correctly. Ensure each tank "clicks" firmly into place to maintain a proper electrical connection with the printhead.
Frequently Asked Questions
What is the difference between PGI-650 and CLI-651 cartridges?
The PGI-650 is a larger tank filled with pigment black ink, which is designed for printing text on plain paper. The CLI-651 tanks (including the small black, cyan, magenta, and yellow) contain dye-based ink, which is specialised for photo printing and producing vibrant colours on glossy media.
Can I mix genuine Canon cartridges with compatible ones in my MX726?
Yes, the MX726 allows you to mix and match. You can replace a single depleted genuine tank with a compatible one while leaving the other genuine tanks in place. The printer's internal monitoring system will still track the levels of each individual tank.
Why does my printer say a tank is empty when there is still ink visible?
Canon printers use a combination of an optical sensor and a droplet-counting microchip to estimate ink levels. To protect the thermal printhead from damage caused by running dry, the printer will signal "empty" slightly before the reservoir is bone dry. This safety margin ensures your printer remains operational for the long term.
