1.5.2 Power Supply Board (C137 PSB/PSE Board)
The power supply board (C137 PSB/PSE Board) consists of an RCC switching regulator circuit. This board is
equipped with a power switch, connected to the secondary circuit. Thus, if the printer is turned off, it can
continue to operate to eject the paper and perform the head-capping operation. The power on/off signal is
always monitored by the E05A09 gate array on the C164 MAIN Board, and the logic system recognizes the
power switch status.
1.5.3 Control Panel (C137 PNL Board)
The 15 LEDs on this board indicate error status (there is no buzzer system). By using the 6 buttons in
combination with one another, you can operate the printer in each protected mode (cleaning color or black ink
systems, exchanging ink cartridges, running a self-test, setting default values, resetting the printer, and
EEPROM clearing).
