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 operations for the maintenance mode in models with touch panel, keys of the software keypad
displayed on the touch panel are also used. Only when a key needs to be limited to the one on the control
panel or on the touch panel, this chapter describes a key, for example, as "the Copy key on the control
panel" or "the Scan key on the touch panel." If a description says just "the 5 key," you can use either the 5
key of the numerical keypad on the control panel or the 5 key of the software keypad on the touch 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).
NOTE: This chapter includes descriptions of facsimile functions which a DCP does not support.
