Epson Artisan 1430 - Paper feeding issue

I noticed recently that my prints had been coming a bit crooked, and when I took a peek inside, I found these small rollers and pin.

The roller attached to the pin was jammed under the left side marked in the picture below. The other roller was just hanging loose on the sponge pad.

I can still print things out "successfully", but it doesn't feed the paper straight or sometimes it will jam up. I'm definitely an amateur when it comes to printer maintenance, but these parts have to be the culprit. Any suggestions as to where and how to put these pins back?
