CAUTION:
To avoid an over current situation, the resistance of the drawer kick-out
solenoid must be 24
Ω
or more.
Output waveform: The output shown in Figure 3.2 are inputs to points A and B
in Figure 3.3
t
1 (ON time) and
t
2 (OFF time) are specified by
ESC p
or
DLE DC4.

< Figure 3.2 Drawer Kick-out Drive Signal Output Waveform >
4) Drawer open/close signal
Input signal level (connector pin 3):
“L”= 0 to 0.8V
“H”= 3 to 5V
< Figure 3.3 Drawer Circuitry >
NOTE:
1. Use a shielded cable for the drawer connector cable.
2. Two driver transistors cannot be energized simultaneously.
3. The drawer drive duty must by as shown below.
ON time
≤
0.2
(ON time + OFF time)
4. 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 over current could damage the solenoid.
6. Do not connect telecommunication network to the drawer kick-out connector
.
