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

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
