The amount of ink is memorized in theEEPROM mounted to the ink tank.The amount of the ink remaining in the ink tank is detected as a dot count according to the data memorized in the EEPROM.When the electrodes mounted to the hollow needle detect a con-conductive state, a message appears on the display to indicate that the ink is nearly empty. If thedot count reaches the prescribed value, the ink tank is considered to be empty.b) Ink portWhen the ink tank lock lever is pressed down, the hollow needle enters the ink port (covered with a rubber plug), establishing an ink passage between the printerand ink tank.c) Air passageWhen the ink tank lever of the printer is pressed down, the hollow needle enters the air passage (covered with a rubber plug) and thus the internal pressure of theink tank is released, maintaining the internal pressure constant.d) Notches for preventing incorrect insertionThe ink tanks have notches for preventing incorrect location.
