Instrumentarium Dental Express Imaging Plate System
Instrumentarium · Model Dental Express Imaging Plate System
Thin, flexible imaging plates 100% active area No cables Plates compatible with film holders EXPRESS imaging plate system supports Occlusal 4C.
Key tips
- ·Biological-indicator verification applies to dental sterilizers exactly the same as hospital CSSD - no exception for smaller units.
- ·"Sounds different" is often the first real report of handpiece bearing wear, not an outright failure - investigate early rather than waiting.
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.
Poor film quality (fog / streaks / light films)
HighSymptoms: Fogged, streaked, mottled or under-developed films; density drift on the sensitometric strip.
Root cause: Exhausted or wrongly mixed chemistry, wrong developer temperature, or dirty / worn rollers.
Film transport jam / mis-feed
MediumSymptoms: Film jams between racks, does not advance, or comes out crumpled.
Root cause: Worn or misaligned transport rollers / racks, worn drive gears, or a crossover-rack fault.
Developer temperature / heater fault
MediumSymptoms: Developer not at set temperature, density varies through the day.
Root cause: Heater, thermostat / sensor, or recirculation-pump fault.
Replenishment pump fault
MediumSymptoms: Chemistry not replenished, developer / fixer levels drift, films degrade over a batch.
Root cause: Worn replenishment-pump tubing or a pump fault.
Dryer fault
LowSymptoms: Films come out damp.
Root cause: Dryer heater or blower fault.

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: Fogged / streaked / light or mottled films
- Run a sensitometric strip and read Dmin, speed and contrast against the control chart.
- Confirm the developer temperature and that the chemistry is fresh and correctly mixed.
- Clean the transport and crossover rollers and racks.
- Check the replenishment rates and that the replenishment pumps deliver.
- Change the chemistry and re-run the strip.
Symptom: Film jams between racks / does not advance / crumples
- Open the racks and clear the film; note where it hangs up.
- Inspect the rollers, guide shoes and drive gears for wear or misalignment.
- Check each rack is fully seated and aligned.
- Run several test films.
- Replace worn rollers / gears as found.
Symptom: Developer not at temperature / density drifts through the day
- Check the developer heater draws current and the thermostat / sensor reads correctly.
- Confirm the recirculation pump is running.
- Compare the developer temperature to an independent thermometer.
- Replace the heater or thermostat / sensor as isolated.
- Re-run a sensitometric strip.
Symptom: Films come out damp (dryer fault)
- Check the dryer heater and the blower run.
- Confirm the air path and filters are clear.
- Check the dryer temperature setting.
- Replace the dryer heater or blower as isolated.
- Re-run and check for dryness.

- RECALL
Instrumentarium Dental has delivered a number of FOCUS 3.0 Intraoral X-ray units in November 2013 with a potential flaw in the mounting hardware. A number of wall mount units were delivered with FOCUS X-ray machines that had not been properly welded at our supplier. As a result of the incomplete welding operation, the wall mount unit on the FOCUS X-ray unit may not properly support the unit as expected, which could cause the unit to drift. Depending on the extent of the shortened or missing welds, there is also a possibility that the wall mount unit will fail to support the weight of the unit, resulting in the FOCUS X-ray unit falling unexpectedly from its mounted position.
- RECALL
There may be a material defect in the up/down movement axle of the unit. This may cause the upper part of the unit to suddenly come down.
