11.3.3.3. Elevation Motor Control
1. Elevation Motor, which moves Stack Tray up and down, is a +24V DC brush motor. The control circuit
is shown below.
2. It is controlled by the combination of signals from P52 and P53 of IC2 in P.C.B. (PBA-CONT). Stack
Tray is elevated when H is output from P52 and P53 respectively, and Stack Tray is descended when H
and L are output from P52 and P53 respectively.
3. Motor stops and brakes when L and H are output from P52 and P53.
11.3.3.4. Staple Motor Control
1. Staple Motor, which carries out stapling, is a +24V DC brush motor. Its control circuit is shown below.
2. It is controlled by the combination of signals from PF1, PF0 and P50 of IC2 in P.C.B. (PBA-CONT).
Stapling is done when L, L and H are output from PF1, PF0 and P50 respectively. Staple is at home
position when H, L and L are output from PF1, PF0 and P50 respectively.
3. Staple Motor stops and brakes when L, H and L are output from PF1, PF0 and P50 for forward and
reverse rotations.
11.3.3.5. Large Gear Solenoid Control
1. An up-and-down motion of the Delivery Unit is performed by changing the drive of feed motor, which is
controlled by the Large Gear Solenoid. If the Large Gear Solenoid is turned on during rotation of the
feed motor, the Delivery Unit will move up and will be opened widely. When the Large Gear Solenoid is
turned off, the Delivery Unit will move down and will be closed.The Solenoid is driven by +24V DC. Its
control circuit is shown below.
2. It is controlled by the signal from P27 of IC2 in P.C.B. (PBA-CONT). When the P27 is H, the Large
Gear Solenoid is turned on.
