Canon CLI-521BK - black - original - blister pack

The CLI-521BK stands apart from generic third-party cartridges by pairing Canon's ChromaLife100+ dye-based ink with a precision-engineered print head interface, delivering deep blacks and crisp text that remain stable for decades in archival storage. This original Canon consumable is tuned specifically for the PIXMA photo-centric range, so every droplet lands exactly where intended without clogging or colour drift.

Highlights

• Genuine Canon OEM cartridge – no compatibility compromises
• 9 ml black dye ink for rich, neutral monochrome output
• ISO/IEC 24711 yield of approx. 485 pages
• ChromaLife100+ system for fade-resistant prints
• Blister packaging protects cartridge during storage

In daily use

Installing the CLI-521BK takes seconds: remove the blister, peel the protective tape, and click it into the black slot of a compatible PIXMA MP, MX, or iP printer. The printer automatically recognises the cartridge and resets ink monitoring. Expect consistent, smudge-free text on plain paper and smooth grey gradients in photo prints. Because it uses dye-based black, photos show deeper shadow detail compared to pigment-only alternatives, while documents remain sharp and water-resistant once dry.
