<p>Hi everyone!<br>
Last week, got the exact same black ink drops issue as on the photo with my 4 years old 3880.<br>
After web researches I found out that it is the matt/photo black ink switch that is not working properly.<br>
I went to an Epson repair service shop (in Paris, France). I came with a print with those black drops and the guy confirmed me the origin of the drops.<br>
I left it 2 days and got the switch changed (175 euros + tax). Now it's running well!</p>
