Tried on the fly with a liteon to a BenQ1620. Unfortunately a pentium 4 2.4 doesnot appear to be up to the job. it took 15 minutes to make a copy at 8X.
The scan attached - although acceptable - is the worst the 1620 has ever produced.
I have added a more normal scan - ripped to drive first - for comparison purposes
Looks like you really do need a powerful set up.
