Homebrew PCBs

Ahhh... Now I see that too. The transfer roller is a part of drum 
cartridge. So I need to do mod every time I change the drum (but not the 
toner). But I think this should be not a problem. One drum life for 
making PCBs is more than enought. Even toner cartridge should do a lot 
of PCBs...

I don't know about PCB potential. As I understand the Transfer roller is 
on negative potential (In E260 and Brother), but in curent mod the board 
is simply grounded. Is it cable to the transfer roller disconnected?!?


... and I upload service manual (I see no copyright notice) so other can 
check too...
