Fix an unstable or drifting ink stream caused by viscosity, pressure, restrictor wear, or mechanical vibration.
What a drifting stream looks like
-
Stream wanders or bends during operation
-
Poor drop formation
-
Charge faults or misaligned characters
-
Printer fails to reach print-ready state
Root causes & resolutions
| Cause | Fix |
|---|---|
| Restrictor partially blocked | Replace restrictor and nozzle filter |
| Ink viscosity incorrect | Run Viscosity Monitoring or Clean Ink System |
| Environmental vibration | Stabilise printer and isolate from conveyor |
| Internal pressure cycling | Check pump and filter for over cycling or wear |
How to troubleshoot
-
Observe stream using strobe or inspection window
-
Run Clean Ink System if ink looks thick or sluggish
-
Replace restrictor if stream is curling or arcing
-
Check filter replacement schedule
-
Reboot and test print once stable
