The older and larger models have an excess ink bottle, and after many many hours operation they will ask you to empty that bottle. Usually this is based on a calculation of how much ink is there, rather than a level sensor, so if you tell the printer you have emptied it, but haven't actually done it, it will eventually overflow and make a real mess of you carpet. Some small printers so the same calculation of when the foam/blotting paper is fully saturated and ask you to change it.
