For richer, crisper text, install a Canon 520 Black Inkjet Cartridge with pigment-based black ink specifically designed for text documents. Each Canon PGI-520BK cartridge uses Canon FINE (Full Photolithographic Inkjet Nozzle Engineering) print heads for incredible crispness and detail. These printheads, combined with the rich and crisp LUCIA ink, provide exceptionally long-lasting prints under the Canon ChromaLife 100 system. This item will print up to 324 pages.
