Canon CLI-251GY Standard Capacity Gray Ink Tank

The Canon 6517B001 is a standard capacity gray ink tank for select PIXMA inkjet printers that use individual CLI-251 cartridges. Filled with dye-based gray ink, it refines tonal transitions and adds depth to both color and monochrome prints. When paired with Canon FINE print head technology, the cartridge helps your printer produce photos with smooth gradations and text that remains crisp.

This tank is part of the ChromaLife100+ system, so photos stored in an archival-quality album can keep their color and detail for up to 300 years. The ink dries the instant it reaches the page, which means you can handle freshly printed snapshots or presentation materials without worrying about smudges.

Installation is straightforward. Slide the cartridge into its slot and an integrated LED light confirms that it is seated correctly. A full tank supports up to 780 pages of mixed text and graphics, giving casual photo enthusiasts and small office users plenty of output before a replacement is needed.

Pairing this cartridge with the complete set of Canon inks also unlocks Creative Park Premium, an online collection of postcards, calendars, and craft templates that you can download and print at no extra cost. Whether you are assembling a family photo album, producing artwork for a classroom project, or printing greeting cards at home, the 6517B001 provides reliable color accuracy and long-term durability.
