Mark Lerman did the DLP, I figure if you're going to futz about rebuilding a laminator with custom gearing and then futz about even more adding foil and then futz about touching up the pinholes in that, you might as well hack a $50 printer in the first place.
You can't use a fuser from a laser printer because the rollers aren't far enough apart to allow for a PCB, and can't easily be adjusted.
However if you're set on modifying a laminator, modifying a fuser would be less work - the parts are already rated to handle the heat.
Note that Lerman's DLP method doesn't use the fuser anyway, the toner on the copper board needs to be fused after printing. Someone figured out suspending it above some acetone will cause the acetone vapours to fuse the toner after a few minutes, at which point you're ready to etch.
