CHAPTER 8 MAINTENANCE MODE
This chapter describes the maintenance mode which is exclusively designed for the purpose of
checks, settings and adjustments using the keys on the control panel.
You can customize the EEPROM according to the shipment destination of the machine
concerned. In addition, you can perform operational checks of the LCD, control panel PCB or
sensors, perform a print test, display the log information or error codes, and modify firmware
switches (WSW).
