Fault Cause Black areas of print are too light
- Process temperature too low
- Processing time set too fast
- Exposure time too short
- Developer exhausted, or replenished too little
Developer is contaminated with FX or BX
- Drain and clean all developer containers and the tank of the processor, then mix fresh developer.
Overall image is too dark
- Processing temperature is too high
- Processing time is too slow
- Exposure time is too long
- CD solution in tank was mixed as replenisher, when it should be working strength solution
Processed material shows strips crosswise to transport direction, approximately 2" (5 cm) away from leading edge of print
- Solution level is too low. Refill up to the overflow line to assure full immersion of the print.
Processed material shows gray/brown shade (not fixed sufficiently)
- Processing time too short
- FX/BX exhausted
- Check replenisher. You may need fresh solution.
- FX/BX diluted with water from wash drain. If the processor is not properly leveled, or the water outlet is not properly installed water can overflow from the rinse tray into tank 2.
Processed material shows scratches or darker spots
- Pressure on the emulsion caused by careless handling (fingerprints or creases).
- Dirty or damaged transport rollers
- Scratches in transport direction indicate faults on guiding elements within the rack. Check transport rollers individually. Replace mechanically damaged parts.
Inconsistent processing results in batches of same image
- Enlarger not equipped with stabilized power supply
- Exposure time too short (afterglow from lamp affects results)
- Prints were allowed to age differently between exposure and processing. (Difference in latent image age.)
- Processor not properly leveled; check level of solutions
- Improper safelight; run paper fog test.
Processor does not start automatically
- Print not inserted at left side
- Drive motor defective
Processor does not stop automatically
- Sensor in feed-in tray continuously "sees" prints; clean feed-in tray
- Sensor defective
Set processing temperature is not reached or reached very slowly
- Air in solution pump; drain approximately 2 liters of chemicals and refill them again.
- Fill the machine only with the racks in place.
- Heating element defective
Paper does not transport straight through racks
- Check racks for proper position
- Check that racks are locked down
Magenta cast about 1" (2.5 cm) away from trailing end of paper
- Dirty angled paper guide between CD & BX; dry with a cloth.
Light stripes approximately 1¼" (3 cm) away from paper border
- Insufficient pressure of transport rollers; check supercushion elements and replace them if necessary.
Processing temperature exceeds adjusted temperature
- Air in circulating system and/or pump; drain 2 liters of solution and refill.
- Room temperature is higher or nearly the same as set temperature. (Electrical devices in the processor will cause the minimum temperature to be approximately 3º F (2º C) higher than room temperature.)
No circulation of solution
- Air in pump system
- Dirty pump
- Pump has not been assembled correctly after cleaning
- Pump defective
Processing material is not transported properly
- Check pressure of rollers
- Check position of racks; they need to be secured by rack locks.
