That was going to be my question. Are the cd's that are being spit out CD-R's? That 402 unit is either last year or the year before I think and it may not be cd-r compatible. Other than that you may need to have it cleaned or realigned. Have you tried resetting the cd player? Check for a reset button or just unplug it for about 15 seconds and plug it back in. Just some things to try.
