To inspect the glass optical window:
1. Dim or turn off the main lights in the room.
2. Shine a secondary light source (for example, a flashlight, LED, or cell phone light)
onto the optical window. Hold the light source at the shallowest angle possible.
3. Inspect the optical surface for dust, oil streaks, fingerprints, or cured resin.
Oil streaks appear as a blue or purple haze.
To clean the glass optical window:
1. Use a rubber bulb air blower to gently remove any visible dust from the optical
window. If a rubber bulb air blower is not available, carefully use compressed air.
2. Use a new PEC*PAD to remove any remaining dust from the optical window
with a dry wipe. Wipe slowly, pulling the PEC*PAD toward you and moving
from the left to the right side of the optical window until you have cleaned the
entire glass surface. Each PEC*PAD can be used multiple times by refolding
the material to expose a fresh surface for each pass on the glass panel.
3. Proceed with a wet wipe only if the dry wipe does not clean the glass completely.
4. Apply a small amount of IPA to a new PEC*PAD.
5. Wipe slowly, pulling the PEC*PAD toward you and moving from the left to the
right side of the optical window until you have cleaned the entire glass surface.
6. After cleaning with a wet wipe, dry wipe the glass surface again with a new
PEC*PAD to remove any remaining streaks.
6.4.5 Inspect the Amber Cover
Visually inspect the amber cover for traces of resin, cracks, or other damage. Clean
any traces of resin with NOVUS Plastic Clean & Shine No. 1 and a soft cloth or towel.
Apply tape to seal any crack that does not affect the printer's function.
In the case of a crack that allows light to pass through the cover, replace the cover.
See 7.5 Troubleshooting and Repair by Skilled Persons.
6.4.6 Inspect the Display
Visually inspect the touchscreen display for any traces of resin. Clean any traces
of resin with NOVUS Plastic Clean & Shine No. 1 and a soft cloth or towel.
6.4.7 Inspect the Drip Catcher
Remove the build platform and resin tank to access the drip catcher, which is the
area below the resin tank spout or under the resin cartridge dispensing mechanism.
Visually inspect the drip catcher. Clean any traces of resin or contamination with
isopropyl alcohol (IPA) and paper towels.
6.4.8 Inspect the Shell
Visually inspect the shell for traces of resin or other damage. Clean any traces
of resin or contamination with isopropyl alcohol (IPA) and paper towels.

6.4.9 Inspect the Shuttle Cover
Open the Form 2 cover.
Visually inspect the shell for traces of resin or other damage.
Clean any traces of resin or contamination with isopropyl alcohol (IPA) and
paper towels.
In the case of a crack in the shuttle cover, contact Formlabs or a certified distributor.
6.4.10 Inspect the Z-Axis
To inspect the Z-Axis:
1. Manually rotate the Z-Axis lead screw.
2. As the build platform carrier moves up and down, listen, look, and feel to check
for areas that emit noise or where the carrier sticks or move less smoothly.
3. Visually inspect the Z-Axis to ensure that lubricant covers the full length of
the threads.
In the case that the screw is missing lubricant or if the Z-Axis emits intermittent
noises when printing, lubricate the lead screw of the Z-Axis.
To lubricate the Z-Axis:
1. Remove the build platform and resin tank.
2. Place a clean paper towel over the tank carrier and glass optical window.
3. Remove old and dirty grease from the lead screw using a paper towel.
4. Apply Super Lube with Syncolon (or a comparable lubricant with PTFE) to
the lead screw. Apply the lubricant directly from the container or by dabbing
lubricant onto the lead screw with a gloved hand.
5. Manually rotate the Z-Axis lead screw. As the build platform carrier moves up
and down, listen, look, and feel to check for areas that emit noise or where
the carrier sticks or moves less smoothly.
