As with the monitoring and the controlling of the switches and the motors, the
data select IC and the drive IC are respectively used to detect a pressed key
and to turn on the LEDs on the operation panel board.
When the Sorter key or the Bin Shift key is pressed, CN103-1 or CN103-4
drops to LOW respectively, informing the data select IC of the pressed key.
To turn on the Sort indicator LED, the Stack indicator LED, or the Check
Sorter Paper Path indicator LED, the drive IC drops either CN103-6, CN103-7,
or CN103-8 to LOW respectively.
