NOTES:
1. Two driver transistors cannot be driven simultaneously.
2. The drawer drive duty must be as shown below:
On time
(ON time + OFF time)
≤
0.2
3. Be sure to use the printer power supply (connector pin 4) for the drawer power source.
4. The resistance of the drawer kick-out solenoid must not be less than that specified (24
Ω
).
Otherwise, an overcurrent could damage the solenoid.
