The Canon 731C cartridge is a high quality cyan toner cartridge
that has been produced by Canon themselves. As a result you can
expect minimum fuss and maximum compatibility when using the Canon
731 C laser toner cartridge in your printer.
The toner powder in this Canon 731 toner cartridge has been
specially formulated to work with the Canon Canon i-SENSYS

unit is required as the 6271B002 cartridge itself contains
everything your printer needs to fuser the toner to paper.
