<IC105 (EEP-ROM)>
Backs up adjustment values.
Backs up initial setting data.
<IC107 (communications IC)>
Communicates with the host machine and the saddle stitcher unit.
<IC102 (regulator IC)>
Generates 5V.
<IC109 (regulator IC)>
Generates 3.3V.
The following figure shows the flow of signals between the finisher and the options controller.
