9-26 Process ECP-2E Specifications

Alternate Process Fixer

The Sodium Fixer is recommended as an alternate fixer for use only with a persulfate bleach. The sodium fixer is not recommended for use in the ECN-2 process or as a “House Fixer”.To process a large quantity (more than one tank turnover) of VISION Premier Color Print Film, the normal
replenishment flow rate of the fix may need to be increased by up to 30%.

† Fixer pH may decrease with certain operating conditions when electrolytically desilvering the fixer. If the fixer is not desilvered or is desilvered by the
batch method, the replenisher pH should be 5.00 ± 0.15. Care should be taken to avoid fixer pH lower than 4.5 since lower fixer pH could cause
sulfurization of the fixer. At a higher pH than designated, stain can occur because all the developing agent may not be removed from the film before
the bleaching step.

* If biological growth becomes a problem, Proxel GXL may be added at 0.07 mL/L; or Spectrus NX1106 at 0.7 mL/L. Proxel GXL is recommended
over Spectrus NX1106 as the NX1106 sometimes causes fog in the developer solution.
