Understanding Nozzle Check Patterns: What They Tell You

Understanding Nozzle Check Patterns

The nozzle check print tells us what went wrong and whether repair will succeed.

Healthy Pattern

  • Complete, unbroken lines for every color
  • Consistent thickness across full width
  • No gaps, deflections, or fading

Common Failure Patterns

Missing Lines (Gaps): Nozzles blocked or dead.
  • Scattered = clogging (repairable)
  • Clustered = localized damage
  • Progressive = air bubble
Deflected Lines: Partially clogged — actually a good sign, usually cleanable. Complete Channel Missing: Electrical issue — broken cable or driver circuit.
