Reset Fucntion - Epson Stylus COLOR 300 Service Manual

4.1.3.4 RESET Fucntion

Since various ink system management information are stored in EEPROM on the main
board, the information integrity need to be kept even after the combination of the printer
mechanism and the main board is altered. Therefore, if any of the component (main board,
printer mechanism or the printhead) is replaced to new one, reset the appropriate
information (counter value or flag).
