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 in order to eject the paper and perform the head capping operation. The power on/off
signal is always monitored by the E05A96 gate array on the C162 MAIN Board, and the logic system
recognizes the power switch status.
1.5.3 Control Panel (C137 PNL Board)
The 14 LEDs on this board indicate the error status (there is no buzzer system); by using the 6 switches in
combination with one another, the printer can operate in each protect operation (color or black cleaning,
cartridge exchanging, self-test, default setting value exchanging, reset, and EEPROM clear operation).
