Original Canon MC-G01 Black Maintenance Cartridge

The C9345 Ink Maintenance Box stores ink that gets flushed from the system during print head cleaning. Your printer and its software will let you know when the maintenance box needs to be replaced. Note: Part C9345 is the same as C12C934591

The MC-20 maintenance cartridge is a replacement for the maintenance cartridge that came with your PRO-1000 Professional Inkjet Printer.
