Canon ImagePROGRAF MC-16 Maintenance Cartridge (1320B010AA): This user replaceable maintenance cartridge is an essential component of your printer. It absorbs ink used in print head cleaning cycles, as well as excess ink overspray while your printer is in use.
Keeps your print head in tip top condition by allowing the head to fire ink in the maintenance cassette periodically, ensuring your print head nozzels remain in good shape.
