Black/Yellow Printhead for the MX1, MX2, & PF-PRO, good for approximately 20,000 prints.
***Please note that Microboards' various disc printers and publishers use different ink cartridge systems. The MX Series & the PF-PRO use four individual ink cartridges & two printheads (which maximizes the number of discs that can be printed per ink cartridge), while the G4/CX1/PF3 only use two ink cartridges, black and tri-color.***
