OK, I just purchased a LPL/Saunders 670dxl. Unfortunately it seems to be missing something, the power supply? Does this unit use a combination power supply/timer? Could I just splice the cord and put a standard plug on it? Does anyone have a manual? Thanks for any help. I'm trying to upgrade from a little Omega C700 (which is really a 6x6). it just barely prints 11x14 from 35mm.
