AGFA NDT M Eco
AGFA · Model NDT M Eco
ECO-logical Design Revolutionary cascade fixing system which reduces the amount of silver in the waste water by a factor of 5 to 10. Reduction of fixer replenishment if the Structurix ecoFix is used. Economical water and electricity consumption. Infrared drying reducing the amount of heat produced in the darkroom to a minimum. Optimal replenishment system as a result of film surface scanning. Intermediate washing which ensures that there is hardly any carry-over of developer, keeping the fixer bath in optimum condition. This system also prevents development faults occuring on the film. Design for Recycling Extra attention has been given to the selection of the materials in order to improve the recyclability. Materials or components which can disrupt the recycling process are easy removable. Exact Replenishment The surface area of the film is measured accurately on entry by 5 detector rollers. This unique film area scanning ensures a precise economic, ecologic replenishment operation and reduced replenishment rates. Minimal Running Costs The accurate replenishment, as described above, implies low chemical consumption. In addition, during film processing only an ecologically justified volume of water is used and the consumption of electricity is particularly low due to the infrared drying system.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
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.

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 per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive 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: Fogged / streaked / light films
- Run a sensitometric strip and read Dmin / speed / contrast against control.
- Confirm the developer temperature and that chemistry is fresh and correctly mixed.
- Clean the rollers and crossover racks.
- Check the replenishment rates and pump operation.
- Change the chemistry and re-run the strip.
Symptom: Film transport jam
- Open the racks and clear the film; note where it hangs up.
- Inspect the rollers, guide shoes and drive gears for wear.
- Check rack seating and alignment.
- Run several test films.
- Replace worn rollers / gears as found.
