SERVICE THE X-OMAT X-RAY FILM PROCESSOR
To minimize service problems, it is advisable to inspect the various components
periodically for signs of wear and/or maladjustment. Apply lubricants where necessary.
Question the operators to determine the performance of the processor throughout the
previous period. Inspect the processor for general cleanliness. Make notes to advise
the operator as to the effectiveness of the daily and weekly routine maintenance. Insert
several 14 by 17-inch films and observe them as they progress through the processing
and drying sections. If film cocking occurs, note at which point it first takes place so you
can adjust the defective section.
a. Inspect the Film Guide Assembly (Feed Tray). Refer to figure 2-7.
(1)
Check the film guide assembly for squareness.
(a) Push a 14 by 17-inch film up to the detector rollers.
(b) If the film is not square to the side guide, loosen the wing nuts
under the feed tray and square the side guide with the edge of the film.
(c)
Retighten the wing nuts.
(2) Check the film guide for static. Check the bottom of the feed tray and
the top of the feed stand to be sure they are free from corrosion and dirt. This can
insulate the feed tray from the processor.
CAUTION:
To prevent scratches on the feed tray and damage to the rollers, keep
all foreign objects off the feed tray.
b. Inspect the Detector Entrance Crossover Assembly. Refer to figure 2-8.
(1) Check the cleanliness of the detector roller. Clean with a dry brush such
as a toothbrush.
NOTE:
DO NOT immerse or use water on this assembly.
