Absolutely caked on. For the user, small fortune There's a fiber mattress, often bigger than a kitchen sponge, that receives the ink from "deep cleaning". It's in a semi-sealed compartment and the printer keeps track of how many times it pumps into this waste area. I keep printers a long time if they keep working well. I've had two printers for such a long time they refused to print, with the error "waste ink reservoir full". Internet searches showed me the button dance to reset the counter. I am still using one of them because it doesn't require chipped ink carts so I use inexpensive ink. Sooner or later I imagine it will make a colorful puddle on my desk.
