Orpheus Lab Transport Problem

I have been experiencing intermittent problem with my orpheus lab transport. Occassionly and getting my frequent now, the transport is not able to read any CD I placed in it and will show " no CD" on its display panel. I got to kept on stopping and putting in CD for it to eventually read. Also sometimes it will pause by itself and cant move on unless I jump track. What could be the problem? TQ in advance
You might just have some dirt or dust on the CD player's lens. Try cleaning the lens gently with a cotton swab dampened with isopropyl alcohol, and see if it does the trick.
