DIY DTG printer

Hey everyone, so i've been researching a lot on building a cheap DTG printer of a standard paper printer. I've the necessary parts off from the printer, but seem to have encountered a few problems. I can't seem to figure out what the source of the problem is. The video below shows what's happening along with the errors.

-As for the ink cartridges not showing up correctly, I think that may be due to them being to old for the Epson to recognize after software updates, but I could be wrong.
