A.2 Notes on Supplying the Power to the Printer
• Connect the ex ternal power supply to the power supply connector of the print er. Then plug i n the
external power supply and turn it on if necessary. Be sure not to connect the external power
supply with the wrong polarity. If it is connected incorrectly, the internal circ uit fuse of the printer
may be blown or the external power supply may be damaged.
• The power supply v oltage is within the range of 24 V ± 7%. If the power supply vol tage drops to
the outside of the range above during printing, t he printer stops printing and waits until the
voltage returns to normal and then autom atically begins printing again. Therefore, printing speed
may slow, the print pitch may not be correc t, and some dots in some characters may not be
printed.
• Both hi gh and low voltage errors are shown in table 3.7.3. The flashing patterns are shown in the
table.
• W hen either a high or low voltage error occurs, turn of f the power as soon as possible.
Using in the presence of silicon gas (silicon adhesive, silicon oil, silicon powder, etc.) including
siloxane and of malignant gas (nitric acid, hydrosulfuric, ammonia, chlorine, etc.) may cause
contact failure at contact point s in a mechanical switch and a DC motor etc. in a short time
because of adhesion or oxidization of the i nsulation film.
