Product Description
The Canon GPR-21 compatible yellow toner cartridge from Castle Ink is a direct replacement for the OEM Canon GPR-21, built for Canon PIXMA, MAXIFY, imageCLASS or imagePROGRAF printers. It’s an economical way to keep your printer in service without paying full OEM prices, while still meeting the print-quality standards your team expects.
Yellow drives the cleanliness of greens, oranges and skin highlights. The GPR-21 delivers OEM-matched yellow density so combined colors stay saturated and gradients stay smooth across the page. Every GPR-21 is assembled with a fresh imaging chip (where applicable), color-balanced toner powder, then individually tested before shipping. Castle Ink backs every GPR-21 with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.

Frequently Asked Questions
Will the GPR-21 void my Canon printer warranty? No. Under the U.S. Magnuson-Moss Warranty Act, your printer manufacturer cannot void your warranty solely because you installed a compatible (non-OEM) cartridge.
How does print quality compare to the genuine Canon GPR-21? The GPR-21 is engineered to match the OEM cartridge’s particle size, charge profile and toner densities so day-to-day output should look essentially identical. If you ever see a difference, our satisfaction guarantee covers a free replacement or refund.
How fast will my order ship? Orders placed before 2pm ET ship the same business day from our U.S. warehouse with free standard shipping. Expedited options are available at checkout.
