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
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.
Assay / QC failure across a channel or the whole system
HighSymptoms: Controls out of range, calibration fails, flagged results, drift over a shift.
Root cause: Reagent or cuvette issue, lamp ageing, a probe / mixer / wash-station fault, or ISE-module problems.
Sample / reagent probe clog or crash
MediumSymptoms: Short aspiration, no dispense, clot detection, probe-position error.
Root cause: Clogged or bent probe, or a clot in the sample.
Cuvette / reaction-rotor fault
MediumSymptoms: High cuvette blanks, non-uniform results by position, rotor-drive error.
Root cause: Worn / scratched cuvettes or a wash fault, or a rotor-drive fault.
ISE module fault (Na / K / Cl)
MediumSymptoms: Electrolyte results biased or noisy, ISE calibration fails.
Root cause: Aged ISE electrodes / reference, or a pinch-valve / tubing fault.
Water / vacuum / pressure system fault
MediumSymptoms: Multiple station alarms, priming failures, poor wash.
Root cause: Water / DI supply quality, a pump, or a vacuum / pressure regulator.

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: Assay or QC failure
- Run fresh controls at all levels.
- Confirm reagents are in date, correctly loaded and mixed.
- Run the photometer check and replace the lamp if energy is low.
- Clean the probes, mixers and wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Probe clog or crash
- Inspect the probe for a bend or blockage and clear it.
- Run the fluidics prime / wash cycle.
- Check for a clot in the sample.
- Verify liquid-level sensing and probe positioning.
- Replace the probe if aspiration is still short.
