MRI Dye Injector.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not prime / inject / pressure fault
HighSymptoms: Injector will not advance the plunger, stalls, pressure-limit or motor-fault alarm.
Root cause: Drive-motor / lead-screw wear, a syringe-interface / plunger-ram fault, or a pressure-transducer fault.
Air-detection / air-column fault
MediumSymptoms: Air-detector alarms with no air, or fails to detect air, will not arm.
Root cause: Air-detector sensor or a dirty / damaged sensor window.
Head / control-room communication fault
MediumSymptoms: The console loses the injector head, hand-controller unresponsive, arm / pause not working.
Root cause: Head-to-console cable / wireless link or a board fault.
Heater / warmer fault
LowSymptoms: Contrast not warmed, warmer alarm.
Root cause: Syringe / bath heater or its sensor.
Battery / power fault (mobile heads)
MediumSymptoms: Short run time, will not hold charge.
Root cause: Aged battery pack.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not prime or inject
- Load a fresh syringe and confirm it seats and the ram engages.
- Run the prime / test-inject and note any pressure or motor alarm.
- Inspect the plunger ram and lead-screw for wear.
- Check the pressure-limit setting for the catheter / protocol.
- Replace the drive / ram assembly as isolated and re-verify flow / pressure.
Symptom: Air-detector or communication fault
- Clean the air-detector sensor window and reseat the tubing.
- Confirm the air column is purged.
- Reseat or swap the head-to-console cable.
- Reboot the console and head.
- Replace the air-detector sensor or refer the communication board.
