IMAGE FAILURES

5-1. Image Failure Troubleshooting
Image failures have many possible causes. For troubleshooting, it is necessary to deter-
mine whether a failure is attributable to a basic cause or any other cause.
In this chapter, troubleshooting is divided into "initial checks" and "troubleshooting proce-
dures classified by image failure". If an image failure has occurred, first make the initial
checks, then proceed to the corresponding image failure troubleshooting procedure.
