Went out to dump the black tank this morning and found that last time, I had left all the valves open. It took awhile but the black tank rinser seems to have cleared what was in the bottom of the black tank. DW was worried that the kitchen grey tank or valve may be clogged and is afraid to use the kitchen sink. My thinking is that it is unlikely for any solids (paper or otherwise) to have had an effect on the gray tanks or valves. I have little confidence in the tank level light as I hace seen it resister as being fairly full just after dumping. Grey tank 2 indicator light currently reads 3 lights out of 4. I don't know if there is water in there or not.
