Introduction

Transport System,
Cont'd)
Film is pulled into the processor by the input roller set on the developer rack. The film then
passes through the recirculating developer bath. As it leaves the developer, excess chemi-
cals are squeegeed off by the exit rollers. This process is repeated in the fix, wash and dryer
sections.
Processed and dried film is then deposited in the film delivery area on top of the processor.
Developer System
As the film passes through the developer tank, developer is continuously circulated and
agitated around the rollers in the developer rack.
This developer circulation and agitation is provided by the developer chemistry being drawn
down into the developer circulation pump, located in the base of the tank, and then being
pumped back through the side of the tank, at a rate of approx. 2 gallons per minute.
The developer is replenished during operation by chemicals being drawn from the replen-
ishment tank by a pump controlled by the replenishment circuit. This circuit operates the
pump continuously, with the actual output rate, in ml/minute, being electronically con-
trolled by the processor’s circuitry.
Developer heat is provided by a 500 watt heater located in a heat-exchanger below the tank.
Developer temperature is sensed by a temperature sensor, located in the bottom of the de-
veloper tank.
Developer temperature is factory set at the values shown on Page 1-2, and may be re-
adjusted by the installing technician to temperature values from ambient to 115 degrees f
(46 C.)
Fixer System
The film is fixed in the fix tank. Fixer is agitated, circulated and replenished in the same
manner as the developer. The fixer is not heated.
