o. Inspect the Flow-Control Valve. If the incoming water supply is adequate
but the wash water supply is inadequate, check the flow-control valve at the inlet on the
intake side of the valve for foreign matter. Replace the valve if necessary.
p. Inspect the Developer Heater. If the developer temperature is incorrect,
check to see if the developer heater is defective.
q. Inspect the Fixer Recirculation System. Besides any scheduled preventive
maintenance check, check and flush the system whenever you change solutions.
Use warm water.
Activate the pumps and check the turbulence.
(a) Be sure the splash guard is in place.
(b) Use the drip tray when removing the rack.
If there is no recirculation, be sure that the pump is operating.
r. Replenish the Processor Chemicals. After the developer solution has been
