I've read the forum for a while about timings with a oven.
I cook mine around 180-200°c for 9 minutes and get really good results and longer and the detail looks scorched.
I do 2 mugs at the same temps for 11 mins and 15 seconds and they look good.
Most of the scrap I make is usually my fault and a error in process.
I've only been at this 7 months as a hobby to keep myself busy, but like webtekker says, it's littered with inconsistencies I've not had a session of printing where something doesn't go wrong . It's the most frustrating thing I've ever done but I'm stubborn , I will not let it beat me. I chucked a full box of scrap from the last few months .
I've never used copier paper though..
