Overview and Operating Principle 1-3
· Printer Driving Voltage
Power supply voltage
11
5.0 +0.8/-0.5 VDC
(Ni-Cd battery, nominal voltage 4.8V)
· 5.0 ±0.5 VDC
(when stabilized power supply is used)
· NOTES:
· Can be applied to motor, print solenoid,
and fast paper feed trigger solenoid
· Use the same power supply.
· In all printing pattern used, even during
sending of current to print solenoids, the
voltage drop by the power supply volt-
age and from wiring resistance must be
0.8 V or less. Also, voltage loss in the
driver circuitry (driver saturation volt-
age) must be 0.4 V or less.
· Detector Input Voltage
5.0 +0.8/-1.7 VDC
· NOTES:
· Can be applied to reset detector, timing
detector.
· Can be used with the same printer driver
power supply.

· Operating ambient temperature:
· a) When using the ERC-22
-10× to 50× (14× to 122×F)
(The assured temperature for printing is
0× to 50×C (32× to 122×F))
· b) When using the ERC-09
0× to 50×C (32× to 122×F)
· Operating ambient humidity:
10 to 90%RH (non-condensing)
