Hold in the Feed button for 4-5 seconds, which causes the printer to attempt to "Auto-calibrate." If that doesn't solve it, then slide out the Media Sensor (green plastic bar that sticks out over the labels) about 1 inch from all the way in ("in" = left if looking from front). Then press Feed to clear errors. If still get same error, then look for piece of label or ribbon stuck in that error - ok to blow out with canned air. Then try holding in Feed again for 4-5 seconds to Auto-calibrate again.
