How to check your 3.3V Rail

NOTE: If you do not know how to test and/or have the tools to test you can install this even if the board doesn’t need it with no adverse effects. This kit is installing a separate 3.3v regulator to bring the voltage in spec. These boards are notorious for having issues with their 3.3v rails being too low.

  1. Turn on your printer and get access to the control board
  2. Set your multimeter to DC voltage (if not auto-ranging choose a low value like 10 or 20)
  3. Touch the negative (black) lead on the multimeter to the G Pin and the positive (red) lead to the 3v3 Pin. (see pic below for pins)
  4. If the voltage shows 3.15V or lower, you probably need this kit. If it shows 3.2V or higher, you probably do not need it.

How to Install the Kit

Make sure to follow the installation pictures EXACTLY in terms of the wire connections.Wire color does not matter and the colors of the jumper wires supplied with the kit will vary from the pictures shown below. You will be making 3 connections from the 3v3 Fix Module to your control board. Depending on the LCD you have the installation will be different. See below.
