I also employ a CIS system.  For the three ink channels I do not employ (which presently contain gradually-depleting dilutions of ink I do not use) is it safe to just let them eventually run dry, through evaporation or the occasional nozzle cleaning, or should I substitute the ink in their respective three CIS compartments with some benign replacement solution? I mix my own dilutions of black using Paul Roark's base solution formula. If it is inadvisable to let the channels run dry, could I use the base solution as a replacement, or should I use some cleaning solution?

If you prefer QTR you could easily make a second profile for the other 3 channels and use the sliders to print with all of them.

 Paul:  I'm using K (100%), LK (18%) and LLK (6%).  I'll have to think over your (good, as usual) advice, and decide what to put into the other channels. Regards, Jim
