Epson xp 305 help
It's quite likely that at some point in time you will have attempted to print in black only to receive an error message that you cannot print until a colour cartridge is replaced.
"If ink is not in the tubes from the head to the cartridge, air will be sucked in and therefore cause damage to the print head. This is because the nozzles are in the print head and not in the cartridge. "
What Epson are basically saying is... if this safeguard was not in place, and you sent a print request for black when a colour cartridge was empty, there is a risk of air being pulled into the printhead. This air will ruin the vacuum effect needed for the printhead to pull ink in, meaning your printhead would be at risk of never printing again.
Additionally, if any air is allowed go get into the aformentioned tubes from the head to the cartridge, any remaining ink will coagulate. Just in case you're not a scientist - coagulation in a tube/cartridge is bad, and will lead to you not being able to print again with that cartridge, or to a blocked nozzle/printhead which will require a significant amount of cleaning cycles to budge.
