4.13 Image Failure

4.13.1 Image Failure Troubleshooting
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 (Scanner) or output system (Printer engine).
In this chapter, troubleshooting is divided into "initial checks" and "troubleshooting procedures classified by
image failures." If an image failure has occurred, first make the initial checks, then proceed to the
corresponding image failure troubleshooting procedure.
4.13.2 Initial Checks
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?
Does the paper size set in the paper source match the size of the paper loaded in it?
3. Original
Is the original written in light pencil?
Use the test chart to check the image.
Is the original transparent, or are transparencies being used?
Place a blank sheet of paper over the original and make a copy.
Is the Original Glass dirty or scratched?
Clean a dirty glass, or replace a scratched one.
4. Supplies
Have the supplies, such as the PC Drum, Cleaning Blade, and other parts that affect image quality,
reached the end of their cleaning or replacement cycle?
Are two or more imaging cartridges being used alternately?
5. Adjustment items
Among the adjustment items given in Machine parameter (see Section 3), is there any adjustment that
may remedy the image failure?
