CHAPTER V TROUBLESHOOTING 

1. PREFACE 

 1.1 

Troubleshooting Procedure 

The troubleshooting procedure can roughly be divided into two: 

Level 1 troubleshooting 
The level 1 FIP isolates the presence of various troubles including fail codes. 

Level 2 Troubleshooting 
Level 2 troubleshooting is a procedure in which troubles are classified by FIP, BSD or fail 
codes list. 

 

 1.2 

Notes on Troubleshooting 

• 

When replacing parts, check in advance that the connectors are connected securely. 

• 

When replacing parts, turn the power off. 

• 

If there are several troubles, you may refer to the same FIP again.  Note that the 
judgment may differ in the middle even when the FIP is identical. 

WARNING

 

When the power is on, do not touch the parts listed below.  You may receive an electrical 
shock.

 

• 

HVPS 

• 

LVPS 

WARNING

 

When the power is on, do not remove drum cartridge.  An invisible laser beam may 
damage your eye.

 

 

WARNING

 

Heat roll and pressure roll, and their peripheries become very hot.  Do not touch when 
they are still hot.  You may get burnt.
