I get blue and pink lines on any print and image that has blue color in it

[Weiss810]

Mac OS Sequoia. Everything image I print that has blue color in it prints with pink and blue lines. The cartridges are new. The print heads are not clogged as far as I can tell. I cannot find a way to realign or clean print heads.
