When to Clean
Obstructions on the projector's light path often cause print issues. Check for smudges, dried resin, or other debris regularly.
Remove the Resin Tank
To clean the tank, begin by removing the tank from its cradle in the printer. Gently pull toward you to unlock and then lift up to remove the resin tank.

Wipe Optical Glass on the Printer
Wipe down the glass with Isopropyl Alcohol and a soft paper towel. Make sure you get all of the corners, and clean as thoroughly as possible.

Repeat With Glass Cleaner
Once the alcohol has dried or been wiped up, follow with Windex and a microfiber cloth. Windex will remove any streaks left behind by alcohol.
Check Cleanliness
The glass can appear perfectly clean in normal overhead lighting conditions, even when it is not. Shine a bright flashlight on the glass to verify cleanliness.
