LEDs mounted with 3M tape
Here are several shots showing the way we used LED lighting installed under the front cover of our JV-33.
They came in a strip of individual LED units that could be cut to length. We installed these three years ago, and the second photo shows them ON in a dark room.
First photo is almost too bright to show the lights, as I shot that photo from down low on the floor up into the underside of the printer.
I purchased the LEDs with 120v power supply, and just tapped into a switched line running 120v for the printer.
Whole project took less than three hours, and about $75 bucks.
