X-Ray Film Processors
Introduction
Figure 1-1, AFP Mini-Medical Series X-Ray Film Processor
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 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.
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.

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:

55 sheets per hour
85 sheets per hour
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 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:

Introduction
Transport System,
(Cont'd)
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.
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.
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.)
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.

0000061122
Introduction
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.
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.

X-Ray Film Processors
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.

Mini Med Series
Installation
Dimensions
Mini-Medical Processors occupy 8.0 square feet (22.5" X 24") (57 X 61 cm.) of floor or
counter space. The processor should be positioned to allow easy access to all sides of the
unit for routine cleaning and preventive maintenance. Drain tubes, leading out of the “front”
of the processor, below the feed tray, must be readily accessible.
Weight
The Mini-Medical Processors weigh approx. 110 lbs. when empty, and approximately 160
lbs. when operating.
To support this weight a Processor Stand Assembly is included. Instructions for the assembly of this stand can be found in Section 7, Accessories. If the stand is not used, a sturdy,
stable and level stand, table or counter must be provided.
Ventilation
WARNING: Some processing chemical fumes may irritate eyes and/or respiratory systems
when used in a poorly ventilated area. If the processor is to operate in a confined area,
provide for at least ten complete changes of air per hour.
Provide adequate ventilation for proper machine operation and operator comfort. The processor generates a moderate amount of heat when operating and must not be placed in a
confined space, such as a closet.
For best processing results, relative humldity should be between 40% and 60%.

Connect Replenishment
The processor may be set up to operate its replenishment system in either “Replenish” or
“Batch” mode.
In “Replenish” mode the chemicals will be replenished with fresh chemicals from the
replenisher supply and the overflow will be collected for disposal or routed directly to a
drain.
In “Batch “ mode the developer and fixer chemicals will be recycled from the replenisher
supply to the processing tank and back to the replenisher supply.
Mini Med Series

0000061122
Installation
Replenish Mode
In “Replenish” mode, fresh replenisher will be pumped from the replenisher supply to the
processing tank. Excessive chemicals in the processing tank will flow out of the tank at an
overflow port and into either a container for disposal or an appropriate drain line. In this
manner, constant processing chemical strength may be maintained for longer periods of
operation.
To install the processor for “Replenish” mode replenishment operation proceed as follows:
(See Figure 2-2)
1) Attach the red developer replenisher pickup tube from the developer replenisher pump
to the developer replenisher reservoir fitting.
2) Route the red developer drain line and red overflow line from the processor to an overflow container or drain line.
3) Attach the blue fixer replenisher pickup tube from the fixer replenisher pump to the fixer
replenishment reservior fitting.
4) Route the blue fixer developer drain line and blue overflow line from the processor to the

Batch Mode
In “Batch” mode the replenisher will be recycled from the replenisher supply to the processing tank and will then, via the tank overflow port, return to the replenisher supply to be
recycled again. As the chemical's processing strength becomes depleted, the entire batch is
disposed of and new chemistry installed.
To install the processor for “Batch” mode replenishment operation proceed as follows:
(See Figure 2-3)
1) Route the red developer replenisher pickup tube from the developer replenisher pump to
the developer replenishment reservior or to a container of developer replenisher.
2) Route the red developer drain line and red overflow line from the processor to the same
container as the developer replenisher pickup tube.
3) Route the blue fixer replenisher pickup tube from the fixer replenisher pump to the fixer
replenishment reservoir or to a container of fixer replenisher.
4) Route the blue fixer developer drain line and blue overflow line from the processor to the
same container as the fixer replenisher pickup tube.

Connect Plumbing
Wash water into the processor is controlled by the water solenoid valve. When the processor is in the process mode the solenoid is actuated, allowing wash water to flow into the
bottom of the wash tank. Excess water in the wash tank flows over the overflow port and
down the drain.
To connect the wash water proceed as follows: (See Figures 2-2 and 2-3)
1) Route the supplied reinforced water hose from the output of your water panel to the
fitting on the wash water solenoid under the right side of the processor.
2) Route the clear wash water drain line and the clear overflow line from the utility section
of the processor to the building drain or a suitable overflow container.
CAUTION: If you are draining your processor directly into a sanitary sewer, be certain that
such connections are in accordance with local plumbing codes and comply with all local
and federal EPA anti-pollution requirements.
DO NOT drain the processor into any drain lines that are made of copper pipe as chemical
reactions will quickly damage the pipes.
"No Plumbing" System Option
The available “No Plumbing” wash water recirculation system, P/N 9992305003 (115 VAC)
or 9992305004 (230), allows the installation of any of the Mini-Medical Series processors

Daily Start Up
The daily start up procedure is as follows:
Processor ON,
Fill Wash Tank
1) Close the wash tank drain valve.
2) Switch the Power Switch to the ON position. The processor will start in the process
mode and run for approximately 5 minutes, filling the wash tank. If, at the end of the
process cycle, the wash water has not reached the overflow port, trip the Manual Replenishment switch to initiate another processing cycle.
3) Allow the developer to warm up to operating temperature (Dev Temp light will
cycle OFF). Check for leaks around all hose fittings.
Caution: Always inspect to see that all drain tubes are properly positioned and draining
correctly. All drain tubes must be routed in a continuously downward direction, without dips or loops that can cause airlocks.
Caution: A kink or twist in a drain tube can cause a serious chemical or water spill in
the processor.
Check Developer
and Fixer Levels
If not previously done, check the developer and fix tanks to see that they contain adequate solution. Prepare fresh replenisher if necessary and using the Manual Replenishment switch, top off each tank with chemistry to the overflow port.
Check Drive
With the Power Switch in the ON position, check all turning drive gears to see that they
mesh properly and turn without binding. Make sure the transport rollers are turning
freely, without interference or binding.

Quality Control
A good quality control program is essential to the production of quality radiographs.
It is recommended that a quality control program for your processor be established and
maintained to assure the quality of your output.
Following are some suggestions for those areas that should be monitored. Contact your
film and chemistry technical representative for additional information and assistance.
Developer
Developer activity can be monitored by use of pre-exposed control strips, available
from your film supplier, or by careful monitoring of your production work.
Fixer
Exhausted fixer will usually result in dark streaks in your film’s emulsion that may
appear immediately after processing or may not appear until hours or even days after
processing.
Exhausted fixer can also contribute to transport problems such as jams and will frequently prevent proper drying from taking place, resulting in sticky film surfaces.
The general health of your fixer can be determined by monitoring the pH of the chemistry.
When pH is too high, films may jam in the wash tank and the dryer. To determine pH,
immerse pH test strips, available from your dealer, in the fixer and read its pH value
from the resultant color change on the strip. If the pH rises toward the chemical
manufacturer’s recommended upper limit, dump the old fixer and replace with fresh
chemicals.
NOTE: Only terminal-type silver recovery systems are recommended for use with this
processor. Do not try to re-use fixer after silver has been removed.
Mini Med Series

0000061122
Operation
Replenishment
Replenishment in Mini-Medical Processors consists of “topping” off the developer and
fixer tanks with fresh working solution at the start of each shift and automatic replenishment by the replenishment system.
Automatic replenishment is accomplished by the film tripping one or both of the Film
Feed Switches which, in turn, actuates the electronic replenishment circuitry. Depending on technician set adjustments, the developer and fixer pumps will cycle on and off
during film feeding to replenish the working solution in the developer and fixer tanks.
Manual Replenishment may be required for one of three reasons. They are:
1) To top off the tanks at start-up.
2) To restore chemical strength after several days of shut down.
3) To compensate for a basic under-replenishment condition. (See NOTE below)
NOTE: Chemistry requirements vary by the type of work and average size of films you
are processing. If you find that you must frequently use the Manual Replenishment
switch to add fresh chemistry, it is recommended that you have your technician adjust
the replenishment control circuits as required to allow for adequate automatic replenishment.

Maintenance Program
Maintenance of Mini-Medical Processors consists of cleaning and adjustment operations,
routinely performed, to keep the processor operating correctly. Early in the life of your
processor set up a maintenance program, with specific people responsible for performing
each maintenance task.
Maintenance Records
Good preventive maintenance is essential to assure a long and trouble free life for your
processor. Keeping on-going records of maintenance will help assure that the work is
performed when scheduled.
Figure 4-1 is a Maintenance Schedule that lists tasks to be performed at prescribed maintenance intervals.
Figure 4-2 is a Maintenance Log for keeping monthly records of maintenance performed.
Make additional copies and post near the processor.
Cleaning
Cleaning is the most important form of maintenance. If chemicals are allowed to accumulate on processor parts they can cause corrosion or other damage which may seriously
affect production and output quality.
Perform daily cleaning, as outlined on the Maintenance Schedule, Figure 4-1, as part of the
shutdown procedure.
Weekly cleaning, described below, should take about thirty minutes following the last shutdown and daily cleaning.
Do not replace items removed for daily cleaning until after weekly cleanup has been completed.
Caution: Never use harsh abrasive material to clean racks or processing tanks. Never
use scrub pads such as "Scotchbrite" on rollers.

As film is processed, by-products are released into the developer, fix and wash systems.
These must be removed by regular cleaning. Every month, schedule two hours of processor
downtime to thoroughly clean the developer, fixer and wash systems.
NOTE: This cleaning will replace the scheduled Weekly Cleaning due on the same date.
1) Open the drain valves, drain and dispose of the used developer, fixer and wash water.
Allow the tanks and recirculation systems to drain completely.
Caution: When filling or rinsing the processor tanks, use water no hotter than 120
degrees F (54 degrees C).
2) Bring a small bucket or container of warm water to the processor and place the red and
blue intake hoses going to the replenisher pumps into the container. Press and hold the
manual replenishment switch (located on the upper right hand front corner of the machine)
until the water comes out clear. Remove the intake hoses from the container and press and
hold the switch again until the pumps and lines are purged. Replace the hoses to their
original chemistry containers.
3) Rinse out each tank and then close the drain valves and fill the wash tank with warm
water.
4) Systems Cleaning.
The use of Developer Systems and Fixer Systems Cleaners are recommended for cleaning
the developer and fixer system. Carefully follow the manufacturer’s instructions and precautions. Dissolve any powdered chemicals in water before adding to the tank. Be sure to
accomplish the neutralizing and rinsing steps recommended by the systems cleaner manufacturer.
WARNING: Beware of all rotating gears, shafts and drive belts when operating the
processor with its access panels removed.
5) After the developer and fixer systems are thoroughly cleaned, neutralized and rinsed, fill
each tank with fresh warm water and install the racks. Switch processor ON and allow the
transport and recirculation systems to run for about 15 minutes as a final rinse.

Systems cleaning will remove most, if not all, of the chemical residue from the transport
racks. For additional cleaning and inspection, proceed as outlined below:
A) Remove the rack from the tank.
B) Clean the developer and fix racks without disassembling them.
C) Appropriate Systems Cleaner may be used to remove stubborn deposits. Never use
“Scotchbrite” type pads on roller surfaces. Rinse the rack thoroughly after it has been
cleaned.
D) Inspect all rack end plates for wear. Be sure the rollers turn freely.
Bearing wear differs according to the solution in which the rack is used. Since bearings
tend to wear more quickly in the fixer solution, the fixer rack end plates should be checked
more frequently for wear.
Clean Tanks
Inspect the empty processing tank for foreign matter and, if necessary, use a soft scrub pad
or brush and warm water to clean the tank interior. Flush the tank with warm water and
drain.
Inspect Processor
Check the hose clamps on the developer, fixer and wash pumps and the base of each pump
for leaks. Secure as necessary.
Caution: Do not over-tighten clamps. This can cause leakage or damage to the pump
heads.

with normal use.
Inspection
The belt should be inspected yearly. Replacement is indicated if any of the following
conditions are found:
1) Excessive slack that cannot be corrected.
2) Frayed or badly worn edges.
3) Missing or damaged drive lugs on the belt surface.
Adjustment
CAUTION: Overtightening the belt will cause the belt to jump on the wormshaft
pulley and will cause the saddle bearing nearest the pulley to become excessively
hot.
Adjusting slots to tension the drive belt are provided in the motor mounting plate.
Adjust in the following manner:
1)
2)
3)
4)
5)
Unplug the processor from its power outlet.
Loosen the four motor mounting plate screws. These are accessible on the back
of the processor, below the dryer.

Service Procedure 5-lA
Film Sensors and Adjustments
Mini-Medical processors up to and including S/N MM1899-90
Film sensing for Mini-Medical processors up to and including S/N MM1899-90 was
accomplished by mounting a magnetic reed switch assembly in the center of the upper
edge inside the molded feed tray adapter.
When film is not present in the feed tray, a magnetic pendulum assembly is in close
proximity to the reed switch, wired in a normally closed configuration. This means that
it is held open by the magnet when film is not present. When film is inserted in the feed
slot, the pendulum is pushed upward and away from the reed switch, causing it to close.
This puts a short across pins 1 and 2 of J13 on the ready tone generator board, putting
the machine into the process mode. When the pendulum returns to its position of rest,
the reed switch opens initiating timers for the beeper, wait light and cycle time.
Approximately 8 seconds after the reed switch opens the beeper should sound and the
wait light should go out.
If a machine fails to go into standby, the magnet may have weakened, or the switch may
be stuck in the closed position; or the switch may be adjusted too far away from the
pendulum to activate the switch.
First, unplug J13 from the ready tone generator board. If the wait light goes out and the
beeper sounds after approximately 8 seconds, the switch is either shorted or the magnet
is failing to activate it.
To test the switch, first remove the switch from the machine. Use a magnet to activate
the switch while looking across the switch with a meter set on Ohms. If the switch fails
to open it should be replaced. If it does open, try adjusting it as close to the pendulum
assembly as possible. If this doesn’t help replace the pendulum assy.
If the machine remains in the process mode after unplugging the switch from the J13
connector on the ready tone board, unplug the ready tone board from J13 on the main
logic board. If the wait light goes out after approximately 8 seconds, the ready tone
generator board should be replaced. If unplugging the ready tone board does not clear
up the problem, a rare problem on the logic board itself is indicated.
Mini-Medical processors S/N MM1900-90 and above
Starting with S/N MM-1900-90, Mini-Medical processors feature a new style of film
sensing. This is in the form of two hall-effect magnetic digital sensors (P/N 21878)
located approximately three inches in from the inner right and left sides of the feed tray.
There are now two magnetic pendulum assemblies (P/N 21893), located above the feed
tray, that are used in conjunction with these sensors.
Activation of either switch will put the machine into the process mode. The purpose of
the dual switch arrangement is to accommodate smaller size films. The feed tray assembly
has changed to P/N 21876. (The part numbers given above are for 1 each of the parts.)

Service Procedure 5-1 A
Film Sensors/Adjustments, Cont'd
Film sensor location configuration (See figure 5-1)
Film Sensor Adjustment: These sensors are adjusted at the factory and normally do
not need adjustment. However, should adjustment be required, follow this procedure:
1) Loosen the screw on each small bracket securing the sensors to the molded feed tray
adapter; the sensors may be moved up or down.
2) Locate each sensor upward close enough to the magnet opposing it so that the
machine remains in standby. Raising either magnet by inserting a film should put the
machine into the process mode. If this does not occur in either case, lower the sensor in
question until it does.
Another Method of Adjustment: Since the two Hall-Effect switches are wired in
parallel, simply short out one and position the other until it activates (allow 10 seconds
after repositioning the switch for the beeper to sound and the wait light to go off).
The easiest way to short out one switch while adjusting the other is to open the front
electrical panel and locate the beeper board. It is the smaller of the three boards, and is
located in the upper middle section of the electrical panel. Each switch is connected to
the board by means of a plug at the end of a 3 wire ribbon cable.
Unplug one switch from the board and jump the second and third pins (count left to
right) together. This completes the circuit for this switch. Now you can adjust the
position of the other one. Once this is done, plug the other switch back into the board
and adjust its position. There is no need to unplug the other one while doing this since
you have already repositioned it. The addition of some silicone caulking to each switch
will help assure that they both stay in position.

Cleaning and Servicing
Replenisher Pumps
Mini-Medical Processors utilize two high reliability, low maintenance oscillating pumps
to deliver replenishment to the developer and fix tanks. The following steps will correct
most problems that may occur.
NOTE: These pumps operate on half-wave DC. Attempting to operate them on full
wave AC (without a blocking diode in place) will lead to overheating and failure of the
pump solenoid.
If the pumps run but deliver little or no chemistry:
1) Inspect replenishment lines between replenisher tanks and pump inputs for kinks or
other damage. If installed, disassemble and clean in-line filter(s). Check all hose clamps
for security.
2) Replenishment lines should not be lengthened, nor should the tanks be positioned
such that more than 36" of chemical lift is required.
3) Check valves may be obstructed with debris or crystallized chemistry.
A) If pump will move any chemistry, try cleaning valves in place by placing
pickup tube in a container of warm water, not over 120 degrees F (49 C) and
activatlng the pumps wlth the Manual Replenishment switch. The warm
water will usually remove hardened chemical residue.
B) Stubborn deposits and larger pieces of foreign material may require that
the pump be disassembled for cleaning. Figure 5-4, below, details
disassembly of the pumps.
Clean the valves, using hot water if necessary to remove any chemical
residue. Older valves may require replacement.
When assembling, take care to install the pump valves exactly as they were
removed.

Circuit Descriptions &
Calibration Procedures
WARNING: The following calibration adjustments are made on the Logic Board.
Since potentially fatal voltages are present and easily contacted, these adjustments
must be performed only by qualified service technicians.
Access to the circuit cards may be gained by removing the two mounting screws from
the underside of the feed tray, then lowering the control box door assembly.
All calibrations are done on the Logic Control Board located on the right side of the
opened control box door.
Developer Temperature Control
The developer is heated by a single 500 watt heating element located under the developer
tank in a heater exchange assembly.
Developer temperature is controlled by an IC temperature sensor mounted on the bottom
of the developer tank. This sensor is a constant current generator who’s output is directly
proportional to the temperature of the tank.
The temperature control is a proportional controller that allows full power to be sent to
the heating element during warm-up, when the processor is first turned ON. This will
be indicated by the DEV TEMP light on the control panel or LED L-2 on the logic
board being ON.
When the temperature in the tank is within 2 degrees f (1.1 C.) of the desired temperature,
the controller will start cycling the power to the heater to prevent temperature over run.
At this point the LEDs’ mentioned above will blink, indicating that the temperature is
very near its set point.
The temperature controller signals the triac switch Q2 through opto-isolator U-2 on the
AC interface board. The triac switches line voltage to the heater.
The desired temperature set point is adjusted with trim pot R-20 on the logic board.
NOTE: Clockwise rotation increases temperature. See Calibration Procedure below.
In the unlikely event of an electronic failure, providing continuous full power to the
heating element, an overtemp safety thermostat located on the heater exchange assembly
will open, thus disabling heat. In addition, a protective internal fusible link is present in
the heating element as an added safety feature. When an open heating element is found,
the operation of the triac should also be checked. (The heating element has a nominal
resistance value of approximately 25 ohms).
Note that the temperature controller is disabled if a low level condition exists in the
developer tank.

Developer Temperature Calibration
1. Verify that there is enough conductive liquid in the developer tank to cover the low
level sensor, located in the front wall of the tank. (About 1.5 gallons [6 L.])
2. Turn the processor ON.
3. Rotate trim pot R-20 on the Logic Board several turns clockwise to force the heater
ON. The DEV HEAT LED and LED L-2 must be on steady, if not, continue turning R20 clockwise until both LEDs’ are ON steady.
4. Place a known accurate metal stem thermometer into the developer solution.
CAUTION: Do Not use a glass/mercury thermometer in the processor. If a glass
thermometer should break, the resultant mercury leakage would permanently
contaminate the processor.
5. As the temperature of the solution reaches the desired value, slowly adjust trim pot
R-20 counterclockwise until LED L-2 starts to blink. When the desired temperature is
reached the LED should flash ON only occasionally to indicate temperature is being
maintained.
Dryer Temperature Control
The dryer uses two 275 watt infra-red lamps (heaters), and airflow provided by 2 fans,
to dry the film as it passes through the dryer section.
A thermistor in the dryer section is used as a temperature sensor. Control is provided
by the logic board. LED L-1 on the logic board will light when the dryer is calling for
heat.
The temperature controller signals the Triac switch Q-1 through opto-isolator U-l on
the AC interface board. The triac switches line voltage to the heaters.
Trim pot R-21 on the logic board adjusts the set temperature of the dryer.
NOTE: Counterclockwise rotation of the trim pot increases the set temperature of the
dryer.
The upper dryer blower is controlled by opto-isolator U-3 and triac Q-3. The lower, or
back blower is on continuously

Over Temperature Protection
The dryer is equipped with over temperature protection in the form of a safety switch
located on one of the lamp reflectors. If temperature inside the dryer exceeds 155 f (68
C), the safety will open and remain open until the temperature drops below 105 f (41
C).
If this should happen the dryer should be checked for dirt build up, nonoperating fans
or shorted triac.
CAUTION: In no event should the processor ever be operated with this safety
device shorted or bypassed. Severe equipment and/or personal injury could occur.
Dryer Temperature Calibration
Dryer temperature should be checked by inspecting the film being processed. If the
film is exiting the dryer damp, temperature may need to be increased. If the processed
film shows heat marks (wavy horizontal lines across the film) the dryer temperature
should be reduced.
1. Inspect a piece of processed film.
NOTE: All covers and panels must be on the processor when checking operation of the
dryer.
2. Adjust trim pot R-21 as follows to adjust dryer operating temperature:
Counterclockwise = Increase Dryer Temperature
Clockwise = Decrease Dryer Temperature
3. Process another piece of film and inspect for proper drying.

replenishment. The other method is via the manual replenishment button located at the
front of the processor, known appropriately as manual replenishment.
Two trim pots on the logic board allow the adjustment of cycle length for the developer
and fixer replenishment pumps, thus allowing adjustment for differing processing loads,
materials and other variable conditions.
Before attempting adjustment of the replenishment system, verify that the replenisher
lines are clear and not bent or kinked. If replenishment seems to be below earlier
performance, clean the check valves as outlined in Service Procedure 5-3 before
proceeding.
Replenishment Calibration
The following outlines basic calibration for the replenishment system. Depending on
the customer’s materials, film sizes and production, it may be necessary to make further
adjustments to the replenishment rate(s).
1. Turn the processor ON.
2. Lift the developer or fixer “J-Hook” out of the processing tank far enough to hang it
into a graduated container.
3. Press the manual replenishment button until all air is purged out of the replenishment
line.
4. Empty the graduated container.
5. Feed in a piece of 14" X 17" film and measure the amount of replenishment delivered
into the container. The recommended starting point amounts are:
Developer = 110 ml
Fixer = 120 ml
If these amounts are not delivered adjust the appropriate trim pot(s) shown below until
the 1 minute delivery amount for each pump is as recommended or as required for your
application. NOTE: Counterclockwise rotation increases output per minute.
Developer = R-47
Fixer = R-28

Service Procedure 5-5
Theory of Operation
Solution Temperature Control
Temperature in the developer tank is sensed by an integrated circuit temperature sensor
which generates a current that is directly proportional to temperature.
The signal from temperature sensor is sent to I.C. U2, an LM 3900 quad currentdifferencing amp. The amplifiers in this package amplify differences in current at its
inputs. Two of the amplifiers are connected as comparators comparing the current
generated by the temperature sensor with the current set by the front panel temperature
control. R20 sets the maximum temperature at which the front panel control can be set.
R20 is preset at the factory for approximatly 110°F maximum temperature.
When replacing the Logic board or when replacing U2 or the temperature sensor, R20
must be re-calibrated (see calibration Procedures). The other two amplifiers in U2 are
used as a triangle wave signal which is mixed with the current from the controls. This
gives proportional temperature control supplying less heat as the temperature approaches
the set temperature, and automatically adjusts the amount of heat supplied to maintain
temperature as closely as possible. The action of the temperature control is indicated
by the LED lamp on the front panel and L2 on the Logic Board. When the lamp is on,
the heater is activated.
As the tank temperature approaches the set temperature, the LED will begin blinking
and will remain on for less time as the temperature comes closer to the set temperature.
Drive to the heater is disabled if the solution level in the developer tank drops below the
level sensor probe.
Dryer Temperature Control
Temperature in the dryer transport is sensed by an integrated circuit temperature sensor
which generates a current that is directly proportional to temperature.
The signal from the temperature sensor is sent to I.C. U2, an LM 3900 quad currentdifferencing amp. The amplifiers in this package amplify differences in current at its
inputs. Two of the amplifiers are connected as comparators comparing the current
generated by the temperature sensor with the current set on the board. R21 sets the
temperature for the dryer. R21 is preset at the factory for 135°F maximum temperature.
When replacing the Logic board or when replacing U2 or the temperature sensor, R21
must be re-calibrated (see calibration Procedures). The other two amplifiers in U2 are
used as a triangle wave signal which is mixed with the current from the controls. This
gives proportional temperature control supplying less heat as the temperature approaches
the set temperature, and automatically adjusts the amount of heat supplied to maintain
temperature as closely as possible. The action of the temperature control is indicated
by the LED L1 on the logic board. When the lamp is on, the heater is activated.
As the dryer temperature approaches the set temperature, the LED L1 will begin blinking
and will remain on for less time as the temperature comes closer to the set temperature.

Theory of Operation

Solution Level Sensor
A metal screw located in the developer tank detects when the solution level becomes so
low that there is a danger of the heater becoming dry. If the developer level drops
below the end of the metal screw, the red Low Solution light will turn on to warn the
operator. When the red light is on, the heater is turned off to prevent tank damage. If an
attempt is made to run the processor, it will turn on as usual but the red Low Solution
light will begin to blink, drawing attention to the problem. When the solution level in
the tank is again at the proper level, the red light will go out and heating will automatically
resumes.
Automatic Shut-Off
The processor is preset at the factory to shut off and go into a standby mode approximately
5 minutes after the sensor(s) in the film entry lip is released by the trailing edge of the
film.
This time interval is controlled by adjusting Pot R29. R29 adjusts the frequency of an
oscillator in U6. The output of the oscillator is sent to U5 which divides the frequency
by 16,384. The oscillator is adjusted so that after division, one pulse is output by U5
after approximately 4 minutes. When the sensor is triggered by film presence, it resets
U5 to zero and holds it there. When the sensor is released, U5 again functions and
outputs its pulse after approximately 5 minutes. The output of U5 goes to a flip flop
(U4) which turns off all machine functions except solution temperature control,
recirculation pumps and one (1) dryer blower.
When the reset pushbutton is depressed, the timer is disabled and all machine functions
run continuously.
AC Interface Board
This board connects the low voltage signals from the main logic board and uses them to
switch the various AC components in the machine on and off.
The low level signals are interfaced by six optically isolated TRIAC TRIGGERS (UlU7). These contain an LED which is optically coupled to a small TRIAC Trigger. The
LED in the Trigger is connected in series with the appropriate control panel LED which
indicates whether each component is operating. If either the trigger LED is bad or the
control panel LED is bad, the circuit will not operate.

The Side Plumbing Kit, p/n 9992305002, allows the repositioning of the front mounted plumbing manifold to
either right or left side of a Mini-Medical processor.
1) Following the dimensions on the illustration below, drill four (4) 3/16" holes in the right or left
side of the processor for the manifold brackets.
2) Remove the original plumbing manifold from the
front of the processor (2 screws).
3) Carefully re-route the hoses to allow the plumbing
manifold to be relocated to the right or left side of
the processor. NOTE: It may be necessary to remove and
then reconnect one or more of the hoses from the manifold during this process to obtain the best routing
without kinking the hoses.
4) Install the plumbing manifold into the manifold
bracket on the side of the processor selected. Check
for leaks wlth water or chemicals.
5) Install the filler plate in the front opening.
6) After charging the processor, carefully inspect all
connections for leaks and proper drainage.
