A friend just purchased a 2002 SLK 320 with the MC3010 autochanger.
The head just reports "NO MAGAZINE" so I'm trying to see if it's fixable.

I disassembled the unit and everything seems to be in working order. I checked all the mechanical parts were not stuck and nothing seemed broken.
I reconnected the power; lo and behold it immediately began scanning the magazine and was able to play a disc. So I put it back together and the problem came back.

It would appear that the unit isn't detecting that the magazine is present and so isn't initiating the disc scan. So two quick questions:

1) If you press the eject button on a MC3010 when there is no magazine installed does it still try to eject? Or does it only eject if it thinks there's a magazine installed? On this unit it always tries to eject.

2) Does anyone know how the unit detects that the magazine has been inserted? There must be a switch or sensor somewhere?

Any help would be appreciated.
