These little units are crammed in so it may take a bit of removing to get to where you need to be. Dont worry though its no big deal, a few screws here and there and any circuits plugged in they are easy to remove, you may have to depress either end and pull harder than you think, though dont overpull. The transport and laser will be as one, though the transport workings may be underneath, cogs, bands ect may be hidden from sight, so out it may have to come. Take your time, lay it all out in front as you and it will be a breeze starting in intrepidation ending in elation. Get stuck in!
