The copper just does not get hot enough I would guess.

Got some 8 mil thick clad, tried sending it through an old Laserjet 4.
The panel went through OK, but the toner just didn't stick to it. I
saw a faint image of the board on the copper, and a second print on
paper had two copies of the board on it.
Sigh.
OTOH the lj4 seems to be able to image 3.33 mil lines reasonably well,
and 5 mil lines look nice and crisp. Maybe it will work better for TT
than the 2550N, assuming I can get it onto the board without mangling
the toner.
