Mid-print, the black channel dips and your colour balance goes off. You need the exact replacement, not a 'close enough' cartridge from a marketplace that'll take six days to land on your bench. This is the Canon PFI-4100 Photo Black, part CI4100PBK. Slot it in, close the door, back to work. No compatibility roulette. Just the right ink for your PFI-4100 machine, and you're printing again before your coffee goes cold
