NOTES: 1. Use a shielded cable for the drawer connector cable.
2. Two driver transistors cannot be energized simultaneously.
3. The drawer drive duty must be as shown below:
On time
(ON time + OFF time)
≤
0.2
4. Be sure to use the printer power supply (connector pin 4) for the drawer power source.
5. The resistance of the drawer kick-out solenoid must not be less than the specified.
Otherwise, an overcurrent could damage the solenoid.
