There will be a second warning. It says to prepare a new tank so you can be ready to replace at the next warning. I take off the film wrap but don’t twist the orange cover off until I am ready to actually install the cartridge.
The printer goes through a purge cycle each time a cartridge is replaced, so if you have several cartridges running low you might want to consider replacing all of them at the same time when one of them triggers the ink is out warning.
I'm not getting an low warning yet on any inks in that example. I was just wondering if one of my inks was giving me a warning, would you also replace the CO at this point as well? I am really just trying to get a sense what "low" is and when to replace an ink even though it might have some life left in it.
If I received a low warning I would replace all inks that show as low as CO to minimize purge cycles.
I don't have a Pro-10; maybe CO doesn't give the same warning as ink, but if ink was showing that low I would expect to be getting a low ink warning.
