Office Jet Pro 6975
Microsoft Windows 10 (64-bit)

I have all new cartridges in my OfficeJet Pro 6975. Blue no longer prints as blue, but prints out pink. When I run diagnotics it still doesn't print blue. I've tried copying directly off printer and by using my laptop, but nothing changes.  There are 11,000 pages I ran off. When I run a test page, blue is missing. Black, Red and Yellow prints fine
