Adding screen background light on printer DCP-L2520DW

I bought this printer many years ago, I don’t remember when. Anyway, I had always been thinking on why this printer doesn’t have any light on the screen. I had also been thinking about put it by myself, and finally, I did it.

For putting light on the LCD you just need the following components:

  • 5 white LEDs of size 0603.
  • 5 resistors of 120Ω and size 0603.
  • 3 resistors of 0Ω and size 1206 (0805 is ok).
  • 1 NPN transistor, for example a MMBT2222.

After finishing the installation, when you turn on/off the printer, the light will turn on/off as well. Easy!
