Printer will only print in black and white

[Pikestaff]

My OfficeJet Pro 7720 will only print in black and white.  This appears to be an issue with the printer itself, not with the drivers on my PC, because even the Print Quality Diagnostic Page prints in black and white only.

I've worked through the troubleshooting bot, which did not solve the problem.  I can't believe it needs a new printhead because it was working perfectly last week and it's only done 5,000 pages from new.  Printer drivers and firmware all up to date.  Genuine HP cartridges are installed and about 80% full.  Print heads are clean.  

Any ideas?
