My 4880 with K7 inks has been sitting, without use, for two years. I turned it on, ran a nozzle check and it was not as horrible as I anticipated. After some cleaning cycles which only made it worse, I have done two power cleanings and it is much improved though still showing numerous clogged nozzles. Room temp is 68˚F with 50-52% humidity. My thought is to empty the K7 inks, fill all the carts with Flush and run power cleans until I get nothing but pink. Does this seem like a good approach or is there something else I need to address? Or, due to its extended lack of use, is it beyond hope? Your thoughts are greatly welcomed.
