Troubleshooting Film Defects
Your processor has been constructed for long term use. However, if irregularities
occur, the following information can help to solve the problem. Please check the fol-
lowing items before calling for service.
Films are too light, not enough density
• Bath temperature is too low.
• Developing time too short.
• Exposure time is too short.
• Replenishment rate of developer too low.
• Developer is exhausted or over-diluted: Drain and replace old developer with
fresh developer.
• Fixer solution has been mixed into developer: Renew. Thoroughly clean and
rinse the developer tank before refilling.
• Circulation system is not operating properly.
Films are too dark, too much density
• Developer temperature too high.
• Developing time too long.
• Exposure time is too long.
• Replenishment rate of developer too high.
• Developer chemicals are too concentrated, mix with new developer.
• After replacing the chemicals: Starter is missing.
• Circulation system is not operating properly.
Films will not dry
• If warm air comes out of air channel in the dryer, chemicals and film type
should be checked.
• Fixer solution is exhausted or diluted.
Film has a yellow-green surface.
• Not fixed correctly. Check the film type and fixer chemistry.
• Fixer solution is exhausted or diluted. Replenishment rate of fixer is too low.
Scratches, pressure marks, dirt on film
• Prior to processing films, run cleaner films through the processor.
• Pressure marks caused by careless handling, finger nails etc.
• Rollers are dirty. Clean tanks and roller racks.
Cloudy film
• Level in developer is too low.
• First guide bar of fixer rack is dirty (condensation or crystals). Clean roller-
racks.
• Developer is old or circulation not working.
• For single emulsion film, feed films emulsion (dull) side up.
