Canon ip4000 issue



Here seems an uncommon issue but someone might have seen it.

Nozzle check seems normal.
High quality printing seems normal.
On normal quality I get noticeable banding due to the magenta.

Seems to be the case that not all the nozzles are firing in one of the
directions for the magenta (assuming printer has bi-directional printing
for normal and uni-directional printing for high quality?).

What could be the issue here?
