I’ve just retired my old 1620 and replaced it with a 1640, far from seeing an improvement in my burns, they actually seem to have got worse.
Burning TYG02 at 8X on my 1620 (B7V9), I would typically see PIE ave 1.93, max 9 and PIF 0.05 ave, max 6, jitter 8.0 ave, 9.0 max.
Burning the same batch of media on my 1640 (BSLB) at 8X I get PIE 21.4 ave, 52 max and PIF 0.02 ave, 5 max, jitter 8.21 ave, 9.4 max.
This is with solidburn on for known and wopc on, which gave the “best” results.
Both scans give a quality score of 97, but I’m not happy with this huge increase in PIE. Unfortunately I invested in a couple of hundred of the TYG02’s as they burned so well in the 1620, so I would be grateful for any advice that might help me improve these PIE scores (apart from simply chucking the 1640 and going back to the 1620!).
