Roche URISYS 2400
Roche · Model URISYS 2400
Innovative “load-and-go” convenience. The unique, ready-to-use cassette with 400 onboard test strips Easier, faster, and more convenient loading of test strips Enhanced walkaway time of 20 minutes/up to 75 samples Once-a-month calibration.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Result / QC failure
HighSymptoms: Strip results flagged or biased, QC out of range, colour blocks misread.
Root cause: Expired or mishandled strips, a dirty / aged optics head, or a calibration issue.
Strip transport / feed fault
MediumSymptoms: Strip not transported, jams, or read at the wrong position.
Root cause: Worn strip-transport belt / tray or a position-sensor fault.
Optics / reflectance-head fault
MediumSymptoms: Repeated optics errors, non-uniform reads across the pads.
Root cause: Contaminated or aged reflectance LEDs / optics.
Sediment / microscopy module fault (if fitted)
MediumSymptoms: Poor particle images, flow-cell or camera errors.
Root cause: Flow-cell contamination, a pump fault, or the camera / focus.
Printer / LIS fault
LowSymptoms: No printout, results not sent to the LIS.
Root cause: Printer or the interface configuration.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
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: Result or QC failure
- Repeat with a fresh strip from a correctly stored, in-date pack.
- Run the calibration strip / grey check.
- Run QC controls at each level.
- Clean the optics head and strip tray.
- Quarantine the strip lot if QC fails; refer the analyzer if QC passes but results still look wrong.
Symptom: Strip transport fault
- Clear any jammed strip.
- Clean and inspect the transport belt / tray.
- Check the position sensor.
- Cycle several test strips.
- Replace the transport belt if feed is unreliable.
