Try the following actions in order.
- Hardware Checks
- Diagnostics
Hardware Checks
If any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved.
If the defect appears again upon reprint on the same part, in the same location, proceed to diagnostics.
- Ensure all of the printer's optics are clean for a clear path for UV light.
- Verify the cassette window is cleaned properly, without dust, spots, or streaks.
- Verify the projector path is clean
- M1/M2 printers - check the deck glass
- M3/M3 Max/L1 printers - check the projector lens
Diagnostics
If the above checks & actions did not resolve the issue or do not apply to your print, the following diagnostics may further inform what is causing the issue.
If problems persist, please reach out to Carbon Support.
Explanation & Causes
Explanation
Vertical channels occur when UV light is blocked, inhibiting curing in the blocked pathway. This happens in the same place on every layer, which explains why the defect is vertical.
The UV light can be blocked by
- A piece of dust or debris
- A damaged window
- A dead pixel in the light engine's projector (rare)
Causes
Hardware
The printer or cassette is dirty or requires maintenance to resolve the defect.
Occasionally, a defect may indicate the printer requires servicing [Check Name Here]

| Problem
| Why Defect Presents
|
|---|---|---|
Cleaning
| - Cassette window is dirty - Deck glass is dirty (M1/M2) - Projector lens is dirty (M3/M3 Max/L1) | A dirty or faulty cassette is blocking UV light, inhibiting curing at the defect.
|
Window Damage | - | A dirty or faulty cassette is blocking UV light, inhibiting curing at the defect. |
Dead Pixel
