Description
Figure 1-1, AFP Mini-Medical Series X-Ray Film Processor
This manual contains instructions for installing, using and maintaining the three different
models of the AFP Mini-Medical Series of X-Ray film processors. This series includes the
Mini-Medical, the Mini-Medical/90 and the Mini-Medical/EP processors. With the exception of pre-set processing speed and developer temperatures, these three processors are
identical in appearance, operation, maintenance and service. Differences, where existing,
will be noted in the text of this manual.
The Mini-Medical system includes the processor, with daylight tight film feed tray, support
stand, replenishment tanks, necessary hoses and this manual.
Major processor sections and components are shown in Figure 1-1.
0000061122
1-1
Mini Med Series
Introduction
Operation
The processor is operated from the control panel. Basic processor functions are described
in the following paragraphs. Figure 1-2 is a diagram of the transport system.
Capabilities
Mini-Medical processors develop, fix, wash and dry exposed RP type medical X-ray films
of all sizes, from 4" X 4" (10 X 10 cm) to 14" X 36" (35 X 91 cm).
Hourly production capacity of 14" X 17" (35 X 45 cm) sheets of film, at the indicated, preset, lead edge in to lead edge out time, is:
ModelLead-to-LeadProductivity
Mini-Medical130 sec55 sheets per hour
Mini-Medical/9090 sec85 sheets per hour
Mini-Medical/EP180 sec42 sheets per hour
Transport System
Four removable roller rack modules transport the material being processed through the
developer, fixer, wash and dryer sections.
The developer, fixer and wash sections make use of “Deep Tank” racks to maintain developing quality and improve productivity. The dryer section includes a long path length
vertical dryer to assure material drying at short developing times, reduce space requirements and return the film to the operator’s position for ease of pick-up.
All racks and rollers in the wet sections and dryer are driven from a common drive shaft by
a fractional horsepower ac motor.
For ease of use, and accuracy of processing, developing times and developing temperatures
are factory set at the following values:
ModelDev. TimeDeveloper Temp.
Mini-Medical29 sec90 Degrees f (32 C.)
Mini-Medical/9022 sec95 Degrees f (35 C.)
Mini-Medical/EP44 sec95 Degrees f (35 C.)

Transport System,
(Cont'd)
Introduction
Figure 1-2, Transport System
Before processing film, the processor must first be turned ON and allowed to bring the
developer up to operating temperature.
As the processor warms up, it runs for one (1) process cycle (approximately 5 minutes) and
then remains in the Stand-By mode. In this mode, only the developer heater, one dryer
blower and the circulation pumps operate.
Film being fed into the processor is detected by a dual film sensor assembly located in the
feed slot. When film is sensed, the Wait lamp will illuminate and stay illuminated until
shortly after the trailing edge of the film has passed the sensor(s).
The above activation of the film feed sensor(s) also places the processor into Process mode,
starting the transport system, the dryer heaters and blowers and, as long as the feed switch
is tripped, operating the replenishment system.
Shortly after the Wait lamp extinguishes, an audible signal will sound, indicating to the
operator that additional film may be fed into the processor.
0000061122
An electronic holding circuit will keep the processor in Process mode for approximately 4
minutes after the feed switch is released. This will allow complete processing of the film,
after which time the processor will return to the Stand-By mode to conserve energy, water
and wear on the processor.

Mini Med Series
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 chemicals 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.
Fixer System
The developer is replenished during operation by chemicals being drawn from the replenishment 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 controlled 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 developer tank.
Developer temperature is factory set at the values shown on Page 1-2, and may be readjusted by the installing technician to temperature values from ambient to 115 degrees f
(46 C.)
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.
Mini Med Series0000061122

Developer & Fixer
Replenishment
Mini-Medical Series processors are designed to operate in either “Batch” or “Replenishment” mode. As such, replenishment chemicals may be replenished as necessary, with tank
overflow being directed into a drain or collection container for disposal, or recycled until
exhausted, then discarded and fresh chemicals installed. For additional information refer to
the Operation and Maintenance sections of this manual.
Anti-Crystallization
To prevent the build-up of chemicals on the processing rollers, an anti-crystallization or
“Jog” feature is built into all Mini-Medical processors.
This feature automatically runs the drive system at process speed for 20 seconds every 4
minutes, allowing fresh chemistry to be washed over the air-exposed rollers, effectively
preventing crystallization of chemistry on the roller surfaces.
Introduction
Wash System
The film being processed is washed in the wash tank before entering the dryer. The wash
water solenoid is actuated during the processing cycle and refreshes the water in the wash
tank with tempered water from an external source.
“No Plumbing’’
System (Optional)
The available “No Plumbing” wash water recirculation system P/N 9992305003 (115 VAC)
or P/N 9992305004 (230VAC) allows the installation of Mini-Medical processors without
external plumbing connections.
When using this option, wash water is recirculated from a 7 gallon reservoir, to the processor, and then back into the 7 gallon reservoir.
Processing chemistry (developer & fixer) is recirculated through each respective processing tank and replenishment container until its activity level is no longer satisfactory, at
which time it is drained and replaced.

Mini Med Series
Introduction
Dryer System
As film passes through the dryer, it is subjected to warm air from two linear infrared quartz
heating elements and a pair of fans.
Upon leaving the dryer the film is deposited in the receiving bin.
Cover Interlock Switch
To prevent accidental injury from moving parts, a mechanical safety switch is interlocked
with the processor’s top cover. If the top cover is removed, the processor automatically
shuts down.

Attention:
When testing or operating the processor with water (as opposed to chemistryj), there will be a
LOW LEVEL condition in effect which will disable the solution heater. This is due to the fact that water
by itself cannot conduct well enough. To prevent this, add 1-2 tablespoons of salt or a cup of used or
fresh developer to the developer tank.
