LESSON 4
PERFORM REMOVE AND REPLACE OR REPAIR DEFECTIVE COMPONENTS OF
X-RAY FILM PROCESSORS
Section I. AFP 14-X3 X-RAY FILM PROCESSOR
4-1.
GENERAL
In order to properly maintain the AFP 14-X3 X-ray film processor you must be
familiar with its theory of operation. You must also know how to remove and replace or
repair a malfunctioning component that you discovered during PMCS or
calibration/verification. The following procedures are examples of the methods to use to
correct common malfunctions. For further information on removing and replacing or
repairing defective components of the AFP 14-X3, refer to the manufacturer's service
manual.
OPERATING SEQUENCE--OVERALL OPERATION--AFP 14-X3
4-2.
The operator feeds exposed film into the processor at the film feed tray at the
front of the processor. As film trips the film feed detectors, the processor automatically
changes from stand-by to process mode. When this happens the transport (drive)
system starts, the dryer begins to heat, and wash water flow is initiated. An all roller
transport system moves the film through the developer, fixer, wash, and dryer sections.
This system deposits the processed and dried film into the receiving bin at the rear of
the processor. The following is a technical description of the electronic circuits that
allow this process to occur.
WARNING
As significant damage or personal injury may result from improper
service techniques, only medical equipment repairers thoroughly familiar
with electronic servicing and high voltage repairs should attempt any of
the repairs or adjustments described in this section.
a. When you turn on the S1 ON-OFF switch:
(1)
The developer and fix circulation pump drive starts.
(2)
The processor enters a special start-up mode. In this mode:
(a) The level sensor checks the developer level.
(b) The replenisher pump runs until the level is correct.
