BLOCKED HEADS Epson WF7710

I've had this printer about 2or3months.
Reservoir looked low.
Filled her up.

After a few sheets, yellow stopped printing.
Ran 3 head-cleans 'all except black'. On the third...all the colours are now not working!

I've heard microscopic particles can block the heads. I'm presuming something has got in, maybe tiny particles of dried ink from the reservoir lid during the refilll process. Extremely disappointing and hugely inconvenient.

First time it blocked was 4 wks ago.
I've got some cleaning solution. Guess I will just have to try that again. These situations always knock my business schedule back a few days. Nightmare

Have successfully recovered an epson recently with exactly the same issues as have others here.

what I did....

i took some kitchen towel folded it over and soaked it in isopropyl alcohol 99.9%
and pushed it under the print head and gently mov3d the head back and forth over the paper towel.
then I replaced the paper towel with more ipa soaked into it and left it for a few hours and then did a nozzle check.

I had issues with the yellow not clearing so I left the towel under the head overnight and hey presto all heads clear and printing in the morning.

Apparently its not good to use ipa or kitchen towel but I had nothing to lose.
so don’t take my advice if you love your printer ;)
