I tried to print something on my IP8750 printer and the black text came out blurred.
Ran a nozzle check page and in the pigment black section at the top the vertical lines are doubled , they start at a single point at the top of the box, diverge outwards and then rejoin at the bottom, hence the blurring.
Deep clean cycles and head alignment haven't worked.
The problem only seems to occur when specifying plain paper, if I change the paper setting to a photo paper the print comes out OK.
Any suggestions?
