Here is a result I get with the 3520 and ritek 4x RICOHJPN01 burnt at 8x with nero 6.6. I have tried various firmwares (dee, tdb, 1.04, 1.25, etc), and this is one of the better scans I can get. Surprisingly, anything burnt at 4x produces MUCH worse scans (unfortunately I dont have a screenshot for that atm). Are these acceptable scans? I am worried I might have a bad 3520!
