Replenishment Operation
The replenishment system operates in two modes. The first is by the film feed sensor
being tripped, indicating that material is being processed. This is called automatic
replenishment. The other method is via the manual replenishment button located at the
front of the processor, known appropriately as manual replenishment.
Two trim pots on the logic board allow the adjustment of cycle length for the developer
and fixer replenishment pumps, thus allowing adjustment for differing processing loads,
materials and other variable conditions.
Before attempting adjustment of the replenishment system, verify that the replenisher
lines are clear and not bent or kinked. If replenishment seems to be below earlier
performance, clean the check valves as outlined in Service Procedure 5-3 before
proceeding.
Replenishment Calibration
The following outlines basic calibration for the replenishment system. Depending on
the customer’s materials, film sizes and production, it may be necessary to make further
adjustments to the replenishment rate(s).
1. Turn the processor ON.
2. Lift the developer or fixer “J-Hook” out of the processing tank far enough to hang it
into a graduated container.
3. Press the manual replenishment button until all air is purged out of the replenishment
line.
4. Empty the graduated container.
5. Feed in a piece of 14" X 17" film and measure the amount of replenishment delivered
into the container. The recommended starting point amounts are:
Developer = 110 ml
Fixer = 120 ml
If these amounts are not delivered adjust the appropriate trim pot(s) shown below until
the 1 minute delivery amount for each pump is as recommended or as required for your
application. NOTE: Counterclockwise rotation increases output per minute.
Developer = R-47
Fixer = R-28
