HP OfficeJet Pro 9010 no longer printing yellow or magenta

[coffeeinseoul]

Hello! 

My printer just randomly stopped printing magenta and yellow and I'm not sure why. The estimated cartridge levels are all fine (replaced it about 1 month ago and had been printing fine since then until today) and I have walked through ALL of the cartridge error troubleshooting steps offered by HP multiple times to no avail. It will do some yellow but is missing blocks, and magenta is completely missing from the diagnostic page. My firmware is up to date but I am out of warranty so here I am :') Any additional thoughts or troubleshooting ideas are appreciated, at least I can still print in black and white if nothing else. 

Thanks in advance!
