Morning guys. I have a Numark NDX500 media player that performs fine with the exception of rejecting the disc. When pressing the eject button the mechanism makes the typical sound associated with rejecting a disc but the disc stays in the unit. I have found that the disc can be made to eject by inserting a piece of paper into the slot while pressing the eject button. Anyone have any ideas as to the cause or how to fix the issue? Thanks Paul
