Booklet maker power supply
The stacker unit and booklet maker unit use both 5 Vdc and 24 Vdc power.
Stacker unit power supply route
When power is turned on, 5 Vdc and 24 Vdc are supplied from the product to the stacker controller
PCA. The 24 Vdc power drives the motor, solenoid, and so on. The 5 Vdc power drives sensors, IC
chips on the stacker controller PCA, and so on. Both 5 Vdc and 24 Vdc are also supplied from the
stacker controller PCA to the saddle-stitcher controller PCA. The 24 Vdc power for the motor drive is
shut down when the front door switch (MSW101) is open. A block diagram of the power supply is
shown as follows.

Stacker unit protective function
The 24 Vdc has a fuse or motor driver with over-current protection.
Booklet maker unit power-supply route
When the power to the product is turned on and the door is closed, 24 Vdc and 5 Vdc are supplied
from the stacker-controller PCA as saddle stitcher power. The 24 Vdc power supply to solenoids is
supplied from the stacker controller PCA without passing through protection mechanisms such as
microswitches. The 5 Vdc power drives sensors and IC chips on the stacker controller PCA. The 24
