Greetings Gentlemen,
Have been following this thread and others with interest.

Was intrigued with the temperature that HP was using on their fusers
(ceramic - higher, H. Lamp - lower) so I contacted their Tech Support
and asked them. Seems that their latest model uses a fuser set at 291
degrees F. No info on what temperature the toner melts at.

I'm using an old LaserJet 4L and an equally old cloths iron to do my
work and am not having any real problems. I preset my iron to a mark
between Cotton and Linen. I use an 1-1/2 inch pad of paper below the
board, which I preheat with the iron. When everything's warm, on goes
the board-etc. and the 'ironing' begins. The hardest thing I have to
remember is to not press down real hard. If the board is to be double-
sided, after a bit I flip the board and continue ironing. I generally
do about 2-3 minutes total for a 4x6 board. The largest board to date
has been a single sided 6x18.

Hope the temp info helps,
Mike
