small strip of plastic inside printer has broken how do I replace

There are 3 white ribbons from the Epson printer front wall - attached to the ink cartridge carriage. All of a sudden, the carriage will go all the way to the left (like it is supposed to) but keeps going until it slams into the wall on the left side and makes a terrible noise. It will not return to its proper place on the right side. I would be so grateful is someone can tell me how to fix it. The tiny cables in the back don't seem to be the problem on my Epson printer. It's just that it won't stop on the left side before it hits the wall like it is supposed to. Very frustrating... Please help. Feb 9-2023
