4 LEDs, Check Pins, and Switches by PCB

Of the LEDs and check pins found in the machine, those used in the field are discussed:

Do not touch any check pins that are not indicated in the table. They are for
the factory, and require special tools and high precision.

4.1 ADF Controller PCB

Some LEDs emit light when they are off because of leakage current. This is
a normal condition, and must be kept in mind.
