My wife told me lots of times that i should start using mine a little less. She says that it gets tiring having to always take 2 at a time and she prefers to leave the 4 there because it’s more pratical. The AMS Lite i mean 
That way my ams lite is always loaded with 4 spools, white and black always there and replacing the other 2 when needed. Since my wife is at home, she has to do all the heavy lifting when i send her a message about printing something with other colors. There is no need to put the spools away after each print at all unless you have the printer in a very, very humid place.
