OPERATOR MANUAL
Section 5: Correcting Difficulties
Important
• Many film transport and sensitometric difficulties can be caused or aggravated by inadequate hardening of the
emulsion due to under replenishment of the developer and fixer solution.
• Another cause of inadequate hardening of the emulsion may be deterioration of the developer replenisher
because of age or storage at too high a temperature. Do not mix more than a 2-week supply of developer
replenisher.
