I'm using Paul Roark's 3MK approach in my 1800 and both black
positions and the GLOP position are supposed to contain Eboni. I use
MIS cleaning fluid in the five color positions, but I mistakenly
loaded this fluid in the GLOP position. I realized this before using
the cart, so I emptied the cleaning fluid as best I could by shaking
it, then flushed some water through it, sucked most of that out with a
syringe, then loaded it with Eboni.

Have I damaged anything? Nozzle check was good...
