11.2.4.1.4. Elevation Motor Control
1. Elevation Motor, which moves the Lower Tray up and down, is a +24V DC motor. Its control circuit is
shown below.
2. It is controlled by the combination of signals from P30 and P31 of IC1 in P.C.B. (PWB-A).
3. Lower tray is elevated when H and L are output from P30 and P31 respectively. Lower Tray descends
when L and H are output from P30 and P31 respectively.
4. Motor is stopped when L is output from P30 and P31, and brakes when H is output from P30 and P31.

11.2.4.1.5. Staple Motor Control
1. Staple Motor, which carries out stapling, is a +24V DC motor. Its control circuit is shown below.
2. It is controlled by the combination of signals from P32 and P33 of IC1 in P.C.B (PWB-A).
3. Stapling is done when H and L are output from P32 and P33 respectively.
4. If an anomaly occurs during stapling, P32 and P33 changes to L and H respectively, inverting the
Staple Motor.
