FYI - in regards to head soaks, it's best to never let them go beyond 20-30 minutes in my experience. The "wicking" created will initially cause cross-contamination in the printhead itself, and then if left long enough, will continually siphon ink out of the tanks and down the drain. Hard lesson to learn (I already been there and got my hat and shirt) but pretty sure you won't do that again, lol.
