The Canon PC921 works hard in silence—and its quiet operation is what most users love about this personal copier.  It produces approximately 10 copies per minute without the need to warm up and automatically shuts off when not in use after 5 minutes. It also uses Canon's patented one-cartridge system, which places the toner, drum, and development all in one easy-to-change cartridge, so it’s easier to maintain. Are you in need of a replacement toner cartridge for this copier? Then, you’ve come to the right place. Inkjets offers a wide selection of compatible Canon toner cartridges and printer supplies including the Canon E40. Get up to 25% savings and take advantage of our fast, free shipping.
