CHAPTER 2 TROUBLESHOOTING
1 INTRODUCTION
This section describes the troubleshooting procedures that the service personnel needs to follow if
an error or malfunction occurs in this machine. It is difficult to anticipate all of the possible
problems that may occur in future and determine the appropriate troubleshooting procedures so this
section covers typical cases and recovery procedures. These cases do not cover everything.
However, they can help the service personnel pinpoint malfunctioning parts and serve as a reference
during repair.
1.1 Precautions
Instructions described in Chapter 3 "1 PRECAUTIONS BEFORE PROCEEDING" must be
followed when assembling or disassembling the machine during troubleshooting.
