CHAPTER 5 SERVICE FUNCTIONS
This chapter describes the maintenance mode and other service functions, which are exclusively
designed for the purpose of checks, settings and adjustments of the machine and can be triggered by the
keys on the control panel*.

MAINTENANCE MODE
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 and paper
feed roller/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,
panel PCB or sensors, perform a print test, display the log information or error codes, and configure
firmware switches (WSW).
