Image failures have many possible causes. For troubleshooting, it is necessary to deter-
mine whether a failure is attributable to:
1. A basic cause or any other cause
2. The input system (IR) or output system (engine).
In this chapter, troubleshooting is divided into “initial checks” and “troubleshooting proce-
dures classified by image failures.” If an image failure has occurred, first make the initial
checks, then proceed to the corresponding image failure troubleshooting procedure.
1. Place of installation
•
Is the source voltage normal? Does the voltage vary greatly?
•
Is the copier installed in a hot, humid place where temperature varies sharply?
•
Is the copier installed in a dusty place?
•
Is the copier subjected to direct sunlight?
•
Is the copier level?
2. Copy paper
•
Is the recommended paper used?
•
Is the paper damp?
•
