As you probably have seen in the videos and the guides, standard procedure is to build up the cube until only one edge piece (which has two faces) is left. Then turn the top layer 45 degrees and push in the remaining piece. This requires some force, especially in new cubes. However … You will need all the play that is available in the cube which is why this is best done holding the cube in your hand, not on a hard surface. Allow as many pieces as possible to give way a bit. Alternatively: Each of the six (one face) centerpieces has a screw inside. You may be able to remove one of the six covers and unscrew the piece.

My PC had the same problem. It disappeared when I performed a CMOS-reset. Such a reset is very easy to do. I would recommend looking up the procedure in the motherboard manual of your computer. It’s often a matter of switching a jumper for a few seconds and putting it back. Alternatively you can remove the motherboard’s battery for a few minutes. This operation should not mess up your computer, all it does is resetting the motherboard to its default settings. That being said, I still recommend looking up the procedure in the motherboard manual of your computer.

This problem occurred in my Samsung CLP-315 after I replaced the black toner cartridge. It disappeared after shaking the cartridge horizontally and gently tapping it in order to loosen and spread the toner more evenly.
