Faults Causes Solutions
Keys will not work Equipment in unplugged Plug it in
Fuse is burned Replace fuse
Master switch is off Turn switch on
Circuit breaker is off Turn on circuit breaker
No power supply Wait until supply is normalized
A semicircle appears on Locating cylinder incorrectly Apply the parallelism radiographic
radiographs positioned technique by using the auxiliary lines
of the collimating cylinder
Radiographs show a dark strip Dark room Light has penetrated the dark room.
Prevent sunlight or excessive illumination
from entering the dark room
Control shows a dark strip Faulty electronic circuit Unplug the equipment and call for
technical assistance
Completely dark radiographs Excessive exposure time Adjust exposure time (refer to “Radiographic
Techniques” in this manual)
Excessive developing time In hot weather, the developer has quicker
action Developer Maybe the developer may contain
Note: Kodak developer does insufficient mixture ( water/ developer
not use mixtures ratio – 3:1)
