A.2 Notes on Supplying the Power to the Printer
• Connect the external power supply to the power supply connector of the printer. Then plug in 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 circuit fuse of the printer
may be blown or the external power supply may be damaged.
• The power supply voltage is within the range of 24 V ± 7%. If the power supply voltage drops to
the outside of the range above during printing, the printer stops printing and waits until the
voltage returns to normal and then automatically begins printing again. Therefore, printing speed
may slow, the print pitch may not be correct, and some dots in some characters may not be
printed.
• Both high and low voltage errors are shown in table 3.7.3. The flashing patterns are shown in the
table.
• When either a high or low voltage error occurs, turn off the power as soon as possible.
A.3 Notes on use environment
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 points in a mechanical switch and a DC motor etc. in a short time
because of adhesion or oxidization of the insulation film.
