When I print using my IP8750 printer, the black (PGBK) text is blurred.
The nozzle check page shows the PGBK grid section at the top but the vertical lines are doubled in the centre (BK is apparently OK). Deep clean cycles and head alignment do not solve the problem. However, the problem only seems to occur when specifying plain paper - if I change the paper setting to a photo paper the print is clear and focused.
Can anyone help diagnose the problem?
Thanks
