Digital BW, The Print

Have any of you had excperience of using refillable carts filled with the MIS cleaning fluid instead of colour inks? I only use the 1800 for b/w printing.I love the 3MK set-up, especially now that Canson, Moab & Innova papers are available here.The Canson & Innova look very good. Also discovered that the Moab Entrada paper is available in 13" rolls, so next project is some big panoramas.
