I guess I could have just posted this next image in the first place but where's the fun in that!

Yes, I have 100% black showing on nozzle check! So how did I do it? Not telling......oh go on then. GoonerGary mentioned above using IPA so I cracked a bottle open. Soaked a rag and pushed it under the carriage ensuring it was touching the heads. Hour or so later I started to get the first result above so tried just 1 or 2 head cleans, slight improvement. Soaked again for a little longer and results just kept improving. Third time I left longer, I wanted to leave overnight but I'm always too impatient. So, last couple of pics were the result and I can clearly see black ink soaked into the rag so looks like it dissolved the problem!
I did the usual 2 head cleans and it was really good but just not quite there. OK, break that rule and do a third.....everything spot on! Time will tell but I'll be testing every day to see if it's printing ok.
After what we said about never rescuing a printer from a block I'm chuffed to bits. A small victory but one I'm heading home with to finish up another crap week on a high!
