Reset active voltage VA -15 to -3 V +2 to +15 V
Reset negative voltage VN +3 to +15 V -15 to + 0.8 V
Reset active current IA -5.3 mA (maximum) 1 mA (maximum)
Reset negative current IN -5.0 mA (maximum) -2 mA (maximum)
Input impedance RIN
3 kΩ (minimum)
• AC characteristics:
Minimum reset pulse width: T
RS 1 ms (minimum)

NOTES: • When a signal that does not satisfy the requirements above is input, printer operation is
not guaranteed. When a signal is input to pin 25 (INIT) at the TTL level, the
requirements above must also be satisfied. Although a signal is input to pin 6 (DSR) at
the TTL level, according to the DC characteristics described above, the operation is not
guaranteed and pin 6 cannot be controlled.
• When pin 6 (DSR) and pin 25 (INIT) are open, the printer is operating.
