Processor Description
The KODAK M35 and M35A X-OMAT Processors
are designed to process medical x-ray film in either
sheets or rolls. This tabletop processor is
self-threading and has a 3-rack processing section
with a dryer.
Special Tools
• TL-3230 Sealant
• TL-2244 Motor Oil, 1-oz Tube
• TL-2324 Motor Oil, 12-oz Tube
H112_0089AC
• TL-1481 Potentiometer Adjusting Tool
• 761217 Thermometer
Dryer
Processor Speed
The processor has a roller transport dryer with
approximately slotted AIR TUBES. A thermostat controls the
76 cm (30 in.) per minute temperature from 46 - 65°C (115 - 150°F).

Correcting Difficulties
IMPORTANT
• Many film transport and sensitometric difficulties can be caused or aggravated by inadequate
hardening of the emulsion due to underreplenishment of the developer and fixer solution.
• Another cause of inadequate hardening of the emulsion may be deterioration of the developer
replenisher because of age or storage at too high a temperature. Do not mix more than a 2-week
supply of developer replenisher.
1. Transport Failure
2. Surface Artifacts
3. Abnormal Film Densities
4. Wet Films
5. Low Solution Levels
6. Overlapping of Films

• • Film Feeding Error
Feed only single thicknesses of film. Feed the next film only
after the film feed signal sounds. If there is no film feed signal,
refer the difficulty to qualified personnel.
• • • • Feed only compatible films.
• • Check that all racks and crossovers are seated correctly.
• • Check that the surfaces of all the rollers are clean and smooth, especially in
the developer turnaround assembly.
• • Check that the dryer air tubes are in the correct positions.
• • Remove any dirt from the dryer rollers and air tubes, especially the slots.
Use a bottle brush and rinse with water.
• • • • Check the settings for correct replenishment. Check the replenishment
system: kinks, pump operation, detector switches, and replenishment pump.
• Adjust the dryer temperature control setting to the lowest possible
temperature that still allows good drying.
• Clean the feed shelf and detector rollers.
• • • Clean any bacterial growth in the wash tank with a mild solution of chlorine
bleach. Use 60 mL (2 fluidounces) of bleach per 3.8 L (1 gallon) of water.
Wipe tanks with a soft sponge.
• • Check that the weirs are seated correctly.
Check that the tanks are full.

• • • • • Change any chemicals that were not mixed correctly, are exhausted, or are
contaminated.
Change the developer filter if necessary.
Check that replenishment flow rates are correctly set. Fill the replenisher
tanks if necessary.
Mix the developer replenishment in quantities not to exceed a
2-week supply.
Always use a splash guard and rack drip tray when lifting the
fixer rack to prevent contaminating the developer.
Mix chemicals as directed.
• • • Check that all rollers are in place and positioned and rotating correctly.
• • • Check that all roller gears, sprockets, and idlers are engaged.
• • • Replace any rollers with broken or worn gudgeons.
• • • Replace any bearings that do not allow the rollers to rotate correctly.
• • Check the rack chain tension. Check that the rollers do not hesitate and
that the chain moves smoothly.
• With the processor on, check for movement on the surface of the solutions.
Movement indicates recirculation. If you do not observe any movement,
check that the tubing is not kinked, that the recirculation pump is operating,
and that the developer filter is clean and in position.
• • If the incoming wash water is dirty, clean the rack and tank thoroughly.
Change the incoming water filter. Make sure to use the correct water filter.
• Check that the poppets in the replenishment pump are clean and are not
distorted or worn. If the poppets are preventing proper replenishment, have
qualified personnel clean or replace them.
• Check that the dryer air exhaust is free from any obstruction and is installed
correctly according to specifications in the Installation Instructions.
• • Check that the turnaround assembly is adjusted correctly. Make sure that
the turnaround assemblies are square with the rack.
• • Check the incoming water temperature. Temperature must be between 4°C
(40°F) and 30°C (85°F).
• • Check that the orifices in the developer and fixer recirculation lines are the
correct size and are not plugged.
• Check that the correct bulb and safelight filter are in the safelight and at the
correct distance from the feed shelf and work surface.
• • Check that the top cover and panels are tight on the processor.
Check that there are no leaks in the lighttight gasket.
• 10 x 10 cm films — feed films diagonally if they fail to transport reliably.

• Check the time delay. For all transport speeds, the buzzer should sound
once the trailing edge of the film has advanced 75 mm (3 in.) into the
processor.
• • • • Check that the tank solution levels are at the overflow weirs.
• • Adjust the guide shoes correctly.
NOTE: Most often in the developer turnaround. Adjust the tips of the
guide shoes in the exit turnaround as close as possible to the rack
roller above them.
• Check for solution in the replenisher tanks. Fill if necessary.
NOTE: Do not mix more than a 2-week supply of developer replenisher.
• Check that the correct bulb is in the safelight.
