Canon TR7620 nozzle check issue

[htsea]

Would appreciate some help. I've owned the TR7620 for quite a while and do nozzle checks quite often and I haven't seen anything like this before. The ink is adequate and I print regularly.  Look at the BK pattern - it's not faint or anything but shows up as a curve. I've tried printing photos and texts, look fine. What is going on with this check pattern??
