Only prints in red ink

I posed a question about this a while ago, but I’m gonna do it again with new information. I bought a printer off FB marketplace (and I’m now beginning to understand why it was there), and only one color of ink works. The yellow, cyan, and black will not print. At another user’s suggestion, I bought a flush kit and put cleaning solution through the nozzles of yellow and cyan— black would not go through at all. Even after cleaning out the yellow and cyan, it will only print in magenta. Any suggestions would be helpful, thank you in advanced.
