Fujifilm · Model Dri-Chem NX500i
Simple 3-step procedureFully Automated Procedure 1 step - Set the slide (Dry Slide Reagents) 2 step - Set the sample 3 step - Press START No Parameter Input Required Information of the parameter is incorporated in the bar code printed on the back of every slide. No pre-treatment of sample required Plasma Filter (PF) can cut the turn around time and the pre-treatment process of the sample. It can generate plasma sample by aspirating and separating the whole blood inside the PF within 1 minute. Just set the PF on top of the sample tube and press START. 1. Have the PF card read in the designated analyzer. 2. Set PF on the top of sample tube. - (A) 3. Press Start. 4. Suction unit move to be connected on PF and start aspiration of whole blood.- (B) Easy operation by touch screen# 5.7 inch VGA, 640 480# Qwerty touch Key board. Basic Mode /Advanced Mode are available according to user preference. (Basic Mode: displays operation procedure for one sample only. Advanced Mode: displays operation procedure for one sample and measurement status for previous measured samples.)Only 10μL/Test# Each test needs only 10μL of sample. (CRP needs 5μL/test, ISE needs 50μL/3 tests). Manual pipetting can be also performed when less sample available. Less invasive for newborn at NICU.No calibration required* QC card system# A magnetic card called QC card will adjust the lot variability in the slide reagents.# A QC card comes with every reagent box.# The analyzer memorizes the lot adjustment information once a QC card is swiped. No need to swipe QC in every measurement for the same slide lot. Accurate and reliable test results from long term and field-proven technology & experience Minimize the risk of biological hazard
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Sample probe / pipette clog
MediumSymptoms: Aspiration error, short sample, carryover.
Root cause: Clot/crystal obstruction.
Centrifuge imbalance / bearing
HighSymptoms: Vibration, loud noise, stop error.
Root cause: Worn bearing or unbalanced rotor.
Reagent / wash flow fault
MediumSymptoms: Clogs, high blank, QC fail.
Root cause: Pump tube wear, air in line.
Temperature control fault
MediumSymptoms: Incubator out of range.
Root cause: Failed heater/fan or sensor.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Sample probe / pipette clog
- Confirm the presentation - typically aspiration error, short sample, carryover - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: clot/crystal obstruction.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the sample aspiration probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
