LESSON 2
PERFORM PREVENTIVE MAINTENANCE CHECKS AND SERVICES
ON X-OMAT X-RAY FILM PROCESSOR
2-1.
GENERAL
The X-OMAT Processor is the mechanical link in a system for rapid processing of
specific types of sheet and roll films. The X-OMAT Processor transports the film
mechanically, utilizing rollers, at a specific speed through the processing and drying
cycle. Because of the rapid processing cycle and the mechanical requirements involved
in transporting film between rollers, the X-OMAT Processor requires specially
formulated solutions. These solutions control the swelling of the film emulsion, keep
emulsion tackiness at a minimum, and prepare the film for reliable transport. The
processor maintains the solutions at the proper temperatures. This combination of film,
chemicals, and mechanical transports results in radiographs processed rapidly to
uniformly high quality. If you recognize and understand the importance of this
mechanical-chemical relationship, there will be little difficulty keeping the processor in
top operating condition. You should use the procedures below in a periodic
maintenance program.
OPERATOR LEVEL PREVENTIVE MAINTENANCE CHECKS AND SERVICES
2-2.
Experience indicates that operation with a minimum of service problems depends
upon well-established work habits and good housekeeping. You must train operating
personnel to follow the recommended cleanup procedures.
a. Perform Daily Preventive Maintenance Checks and Services.
Train the operator to perform the daily PMCS as part of the shutdown procedures.
(1)
Turn the power off.
(2) Remove the crossover and the squeegee assemblies. Clean the rollers
with a damp cloth and wipe them dry. Handle these assemblies carefully to avoid
twisting them out of square and to avoid disturbing the guide shoe settings. Refer to
figures 2-1 and 2-2.
(3)
Wipe off all chemical deposits in the processing section.
