Two cartridges are included with the purchase of the printer.
PG-740 is a black cartridge and CL-741 is a tri-color cartridge.

It comes with a 4-color ink system which includes a pigment black ink to get a better output quality.

Canon MX397 includes some software enhancement to improve the output quality.

One of them is Auto Document Fix.
