# Cleaning the Camera Lens

#### When to Clean the Camera Lens

Clean your camera lens only if you notice material build up (or dust) during your post NOVA use inspection. This should only need to be done occasionally as it is difficult for materials to make it to this area of the machine.

#### Steps For Cleaning the Camera Lens

**Step 1:** Wear appropriate PPE. Refer to the SDS of your material. Typically, this means gloves and goggles, and sometimes requires handling in a fume hood.

**Step 2:** Add a dab of isopropyl alcohol to a low-lint wipe and gently wipe the vision system on the underside of the module hub.

**Step 3:** Make sure there are no streaks left behind and you’re all set.
