CHAPTER 2 TROUBLESHOOTING
This chapter details error messages and codes which the incorporated self-diagnostic
function of the machine will display if any error or malfunction occurs. If any error message
appears, refer to this chapter to find which parts should be checked or replaced.
The latter half of this chapter provides sample problems which could occur in the main
sections of the machine and related troubleshooting procedures. These will help service
personnel identify and repair other similar defective sections.
