2.3.8  Control Panel Circuit

E05A89, the gate array for the control panel I/F, has the LCD driver, LED driver and panel
switch input circuit built in. The serial I/F is used for signal transmission between the control
panel and the main control board. The cover open sensor signal on the logic line is directly
sent to the main control board via the control panel board. If the printer cover is open, an
interlock switch function is activated for safety and puts the printer inactive state.
