5-1. Image Failure Troubleshooting
Image failures have many possible causes. For troubleshooting, it is necessary to determine whether a fail-
ure is attributable to a basic cause or any other cause.
In this chapter, troubleshooting is divided into “initial checks” and “troubleshooting procedures classified by
image failure”. If an image failure has occurred, first make the initial checks, then proceed to the correspond-
ing image failure troubleshooting procedure.
