So I have a new problem now when it comes to calibrating. The last week has been good, but today when I turn it on the laser tube makes a very loud bumping sound when it moves down, toward the tray door. It also seem to not be square anymore. As in the left side is moving faster then the right. I have tried using caned air to blow off the tracks, but it keeps doing this and failing the calibration.
When I push everything back to the top left hand corner to reset everything, there is no bumping sound. It moves smoothly. It only happens when it moves itself.
