TG,
A 24" sheet is ok, but, if I understand you correctly, you want to
start the print with the leading edge of the sheet already through the
printing interface where drum meets transfer roller. I don't think this
will work because part of the printing protocol requires the drum to be
cleaned and charged. That said, I don't think I have ever tried it. Might
be fun to try!
An acquaintance of mine, experimenting completely independently of me,
modified a printer so that the pcb slid under the drum on a powered
flatbed platform that was synchronized to the printer so that it moved at
the correct speed and correct timing. He removed the transfer roller
entirely. Seemed to work well, though he used an HP printer, which
do? not work very well for direct printing on copper. He devised a
software workaround to make it work.

I am going to work on this project again this weekend, and I founding
myself wondering something:
Is there a fundamental reason to not use the entire 24" sheet of
89015K115 as the carrier, as opposed to making a 16 inch rounded
carrier?
I am sure you've thought about this, but it seems like you could attempt
to do the line-up of the carrier with the start of the print on the
backside of the printer if you kept the carrier long enough. I know
rigidity of the carrier pcb combination is important, but couldn't you
get the rigidity from reinforcement on the backside too?
Thanks,
