I think we must have bought our 1410's at almost the same time.
I am using Ilford paper & their profiles, but also thought the blues & some greys were a bit off at first.
reading through several forums I ended up on a site that was a review of the 1400 (us version) from when it first came out. The reviewer commented that he had magenta problems with the test unit, but did a print head clean and it resolved it.
I had done a check, which indicated my heads were ok, but after reading that forced it to do a clean and there was a significant improvement
