A.2 Notes on Printer Installation
1) When transporting the TM-U590 series printer, the dampers are in the left side of the slip
section and in the bottom of the paper roll section. Therefore, remove the dampers before
using the printer.
2) 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 ± 10% (21.6 ~ 26.4V)
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.
• When the power supply voltage exceeds 26.4V for a certain time continuously, it is a high
voltage error. When the voltage is below 21.6V for a certain time continuously, it is a low
voltage error.
• Both high and low voltage errors are shown in Table 3.7.3. The blinking 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 Other Notes
• Because this printer uses plated steel, the cutting edges may be subject to rust. However,
this does not affect the printer performance.
• When you move the printer, put your hand under the printer so that you do not apply
excessive pressure to the printer case.
• Do not set any liquids or drinks such as coffee on the printer case.
