Someone dropped a working epson V600 at the local dump reuse-and-recycle, so I took action..!
How to make sure optics are right on the mark, calibrate or such?
A quick Sunday-morning check on a so-so film strip of mine shows it works as intended, but I do not yet a true measure of true rendition.
I also do not have masks - I borrowed the 120 from my own V600.
I also wonder if I could go a bit crazy and try experimenting, on this "free" machine?
Do you have a resolution target of any kind and a IT.8 target?
If not, just do two scans with same settings on both scanners and compare results.
You could go crazy and... sell it. The other way would be to remove the glass plate for glass-free scanning, clean the mirrors if they are accessible without breaking the enclosure, remove protective glass on CCD sensor to cut down on flare, try to cover elements in the light path with antireflective material... Nothing will improve the results substantially but might still be fun and educational.
For some scanners, you need either the film holders or something that puts the necessary "window" in the location that the scanner and software use for calibration. Otherwise the results can be, at best, unpredictable.
