EEPROM Control Driver Circuit
Data for various factory-adjustment items is stored in the EEPROM IC7 on the C265 main board. The size of the EEPROM is 2 K bit since various types of dots are available with this printer and memory allocated for the ink consumption counter is accordingly large. When the printer is turned on, data stored in the EEPROM is transferred to the D-RAM by the ASIC IC3 . In the D-RAM, the ASIC controls various adjustment values, total ink consumption, and current ink usage condition for each color, and...
