Change any chemicals that were not mixed correctly, are exhausted, or are
contaminated.
Change the developer filter if necessary.
Check that replenishment flow rates are correctly set. Fill the replenisher
tanks if necessary.
Mix the developer replenishment in quantities not to exceed a
2-week supply.
Always use a splash guard and rack drip tray when lifting the
fixer rack to prevent contaminating the developer.
Mix chemicals as directed.

Check that all rollers are in place and positioned and rotating correctly.
•
Check that all roller gears, sprockets, and idlers are engaged.

Replace any rollers with broken or worn gudgeons.
•
Replace any bearings that do not allow the rollers to rotate correctly.
Check the rack chain tension. Check that the rollers do not hesitate and
that the chain moves smoothly.
With the processor on, check for movement on the surface of the solutions.
Movement indicates recirculation. If you do not observe any movement,
check that the tubing is not kinked, that the recirculation pump is operating,
and that the developer filter is clean and in position.
If the incoming wash water is dirty, clean the rack and tank thoroughly.
Change the incoming water filter. Make sure to use the correct water filter.
•
Check that the poppets in the replenishment pump are clean and are not
distorted or worn. If the poppets are preventing proper replenishment, have
qualified personnel clean or replace them.
Check that the dryer air exhaust is free from any obstruction and is installed
correctly according to specifications in the Installation Instructions.
•
Check that the turnaround assembly is adjusted correctly. Make sure that
the turnaround assemblies are square with the rack.
Check the incoming water temperature. Temperature must be between 4°C
(40°F) and 30°C (85°F).
Check that the orifices in the developer and fixer recirculation lines are the
correct size and are not plugged.
Check that the correct bulb and safelight filter are in the safelight and at the
correct distance from the feed shelf and work surface.
Check that the top cover and panels are tight on the processor.
Check that there are no leaks in the lighttight gasket.
