Disc Drive keeps spitting out discs

So whenever I insert a disc the drive will think about it for about 3 seconds before spitting out. I would like help diagnosing the issue at hand here. Also here’s a 14 sec video of the problem https://www.youtube.com/watch?v=JToL_3TO... Oh before I forget the reason why the cover was off was I was dusting the system off for the first time.
