2.3 Page mode
Printing in the page mode starts only when receiving the print command (FF). For the detail
of the commands, please refer to the section 5.5.
2.4 Power supply specifications
1) Voltage: DC24V +/-5%
2) Consumption current
At printing ASCII (About 16% print ratio)
At printing bit image (Max.100%)
Notes:
1. Thermal printer runs a large excessive current for printing. Please use a power supply
with good response for print quality and capable of running high peak current.
2. When the power supply cable is excessively long and its diameter is small, voltage drop
may occur and cause error. For this reason, a short cable with large diameter is
recommended (above AWG#18). If such a cable is not available, connect a cable near
the printer and locate a low ESR electrolyte condenser in 2200 - 6800ƒ Ê between the
power supply and ground. The voltage
2.5 Reliability
1) Head life: Average resistance change ratio; less than 15% excluding dust and foreign
objects.
Pulse
Wear distance: More than 50Km (for recommended paper)
2) Operation environment: Temperature, 0 - 45°C,
3) Storing environment : Temperature - 20 ~ 60°C
4) Safety regulation
5) EMC

Note 4: Thermal printer runs high transient current for printing. For this reason, it is
recommended to use such a power supply that has high response performance to
guarantee print quality, in addition, that support high peak current to run.
Note 5: When power supply cable is excessively long and small in diameter, the voltage drops
to cause error by wrong voltage sensing. To avoid this type of error, make sure to use
proper size of cable. The size recommended is less than AWG#18. If such a cable is
not available, connect the cable near the printer and place low ESR condenser
between 2200micro~6800 micro, capable of 35V voltage loading.
Standby
: More than 100 million pulses (for recommended paper)
* Print guaranteed: 5 - 40°, Should not be condensed
* For a long storage, place paper between head & platen
