Condition : Simultaneous current-carrying dot numbers – 288dots.
[CAUTION]
– Since the printer may reach to degradation and breakage at once when power voltage
exceeds absolute maximum rating even for a moment, DO NOT exceed absolute
maximum rating under anytime of conditions.
– The current may be big at the peak time, depending on the power voltage and printing
contents, power supply with enough capacity is required to secure a good print quality.
Also, make sure to connect all of the wiring for power supply relations. Please have
enough
Attention to allowable current of wire material.
– Although current capacity of thermal head itself is [10.2A], current capacity of
connector cable is not included to this, determine number of dots applied for
simultaneous current-carrying within the current capacity.
– If power supply cable is excessively long, the operation may become unstable. Cable
should be made as short as possible. If not possible, connect cables near the printer
and place an electrolysis condenser of approx. 2200
μ
. Rating voltage is more than
32V.
– Make sure to set element for excessive current protection and appropriate fuse to the power line.
– Make sure to use power supply complied with LPS standard.
