Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
These symptoms point to either a clogged/contaminated print head, or a faulty print head (or the logic board that controls it).
You can try going into the setup/maintenance menu on the machine and running the “clean print head” function repeatedly, up to 5 times total, testing after each.
If it still doesn’t print anything, you’ll need to do a manual cleaning as a next step.
Let me know how the built in cleaning function works, and I’ll guide you through the manual steps next.
Can you also confirm the age? This is a 2014 model so I just want to be sure I'm clear on you saying it is only 6 months old.
Do you need more help with this?
