How did you do it? Can you explain in English what settings you choose in the app? because according to the video it does not warm up the top sheet properly and the transfer is not printed.
apply very thin layer hand cream to the printer head with a napkin, no more melting or sticking. (the plastic sheet will be up when inserting the transfer paper. dont forget remove all yellow sheets)
I think there are sensors that check whether the paper is finished or not. She may have glued it to overcome problems with transparency. Sometimes when you insert thin paper, the printer stop while printing. @@topiz
