Minolta 4000 Code C 0D50

[minolta35]

Machine often gives the duplex code.I can\'t see anything abnormal.But sometimes works properly, sometimes duplex doesn\'t work.All gears are new and no problem with belt.

Just forget about solving that problem. Just learn to live with that. It is a old machine.

I have encountered that problem before. My experiance with that is the duplex drawer moving or sliding out during operation. Try adjusting the drawer, so it will stay in place.
Hope this helps
