    I have noticed that the PGBK on my MG5250 is not printing well.

    The Nozzle Check print shows the "top half" squares, but the "bottom half" are all blurred, fuzzy or do not print at all.

    If i print text in Fast mode, some lines print whilst others not. If I print in High mode, all text prints, but the black is not so vibrant and black, it looks a bit greyish.

    I have tried 3 new Original cartridges and the problems is identical. I have done 5 deep cleans. I have removed the print head and cleaned it thoroughly with an Isopropyl Alcohol solution.

    All the other colours, including dye black print perfectly.

    I am out of ideas :(

    Anyone experienced a similar problem and managed to solve it?
