I just put up a new printer, the stupid instructions didn't give out details or warnings and the paper shows twisting off the orange cap which I did and the rubber part is stuck in the cap can't get it out to put it on the cartridge, What should I do.
I have no idea what kind of printer or ink you're trying to use, but if there's a cap in that part you're talking about that needs to be on the ink cartridge, try using needle-nose pliers or tweezers to grab the lip of the cap and pull it out. Otherwise try to leverage it out with a small flathead screwdriver or knife (be careful not to cut it or yourself).
