Troubleshooting 3 of 6
Machine Problems
Suspect the machine when a known-good file and validated material fail on one device or when output changes as equipment condition changes. Follow manufacturer diagnostics and safety procedures before adjusting production settings.
Machine diagnosis
| Symptom | Likely area | Check | Correction |
|---|---|---|---|
| Banding or missing printed output | Nozzles, ink delivery, alignment, feed, or maintenance | Run the manufacturer-prescribed diagnostic | Complete approved cleaning, alignment, maintenance, or service |
| Placement shifts | Fixture, platen, feed, registration, or alignment | Test with a known placement target | Secure the product and recalibrate or realign the setup |
| Engraving is uneven | Focus, bed level, optics, motion, or material position | Run a controlled test on approved material | Correct focus, leveling, cleaning, or mechanical setup |
| Output changes during a run | Temperature, consumable level, contamination, drift, or mechanical condition | Compare early and later units and review machine indicators | Stop the run, isolate affected units, and correct the equipment condition |
| Colors shift on one device | Device profile, calibration, ink state, or machine configuration | Run approved device and color checks | Restore the validated device state and preset |
| Machine reports an error | Device-specific fault or unsafe condition | Record the exact code and job state | Use official documentation or qualified service; do not bypass safety controls |
