AFP Imaging Corporation warrants to the original purchaser that each newAFP product is free from defects in
workmanship and material for 12 months from date of installation or 18 months from date of sale, whichever occurs first.
If no warranty card is returned to AFP within 30 days of installation, the maximum warranty period will be 13 months from
date of shipment from AFP’s warehouse. In the event any product or component of equipment is replaced by AFP
under this warranty, such item is covered by this same warranty for the remainder of the original period or ninety days
from the date of installation, whichever is longer. AFP’s obligation during this warranty period is expressly limited to repair
or, at its discretion, replacement of non-expendable original equipment or components which it finds defective.
Upon authorization from AFP, a proper party asserting a claim under this warranty shall prepay all transportation costs
and return the equipment to a location specified by AFP. That party shall also bear all reasonable service and labor
charges incident to any warranty claim. This warranty does NOT APPLY (1) to any expendable parts including, but not
limited to lamps, photocells, or consumable supplies (2) to any AFP product or component which has been repaired or altered
with parts or by persons not approved in writing by AFP, provided, however, that such approval is not to be
unreasonably withheld, or (3) to any product on which the serial number or name has been altered, defaced, or removed.
This warranty also shall NOT APPLY to any AFP product whose unsatisfactory performance or condition is due to:
- Instability of sensitized materials or chemical concentrations
and replenishing rates of chemical and wash water immersions or sequences;
- Lack of applied adequate quality production control procedures as
recommended by the sensitized material and chemical suppliers;
- Changes in characteristics or process procedures made by suppliers of
sensitized materials or chemicals after delivery of the AFP product to the purchaser;

Introduction
Mini Med Series
0000061122
Content
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 excep-
tion 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.
Description
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.
Figure 1-1, AFP Mini-Medical Series X-Ray Film Processor
1-1

Introduction
Mini Med Series 0000061122
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, pre-
set, lead edge in to lead edge out time, is:
Model Lead-to-Lead Productivity
Mini-Medical 130 sec 55 sheets per hour
Mini-Medical/90 90 sec 85 sheets per hour
Mini-Medical/EP 180 sec 42 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 devel-
oping quality and improve productivity. The dryer section includes a long path length
vertical dryer to assure material drying at short developing times, reduce space require-
ments 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:
Model Dev. Time Developer Temp.
Mini-Medical 29 sec 90 Degrees f (32 C.)
Mini-Medical/90 22 sec 95 Degrees f (35 C.)
Mini-Medical/EP 44 sec 95 Degrees f (35 C.)

Introduction
Mini Med Series
0000061122
Transport System,
(Cont'd)
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.
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.

Introduction
Mini Med Series 0000061122
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.
