CHAPTER 9 MAINTENANCE MODE
This chapter describes the maintenance mode which is exclusively designed for the purpose of checks,
settings and adjustments of the machine using the keys on the control panel.
In the maintenance mode, you can update memory (EEPROM: electrically erasable programmable
read-only memory) contents for optimizing the drive conditions of the head/carriage unit or the paper
feed roller and paper ejection roller in the engine unit, if those units have been replaced, or for setting
the CIS scanner area, for example. You can also 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).
