Brother MFC260C Service Manual page 293

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).
For models with a cordless handset, the maintenance functions dedicated to cordless handsets are
provided.
