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
