ST said something about failed tests not
completly cleaned from the copper affecting the
inkjet tests.

I found something similar with toner transfer.
(way way back when I strayed from the path
of the righteous for a few years and like a
foolish child forsaked the photo process)

I always used to have a high percentage of
first tries not come out too well.  But the
second go after cleaning off the toner with
acetone it transfered close to 100% everytime.

So I just started smearing toner and acteone
on the blank copper.  Helped heaps.

NB - my toner transfer was done with faber
castel brand OHT (later 3m GC3300).  People
usig inkjet paper for TT may not find that
step useful.
