Output: DC24V±5%, 1.5A
Caution: Only use authorized AC adapters.
Caution: Do not use the bundled AC adapter and Power cable for any
electrical equipment other than this printer.
2-2. Paper specification (Thermal paper)
Be sure to use thermal roll paper that conform to the following specifications.
- Paper width: For paper 83mm wide, 830
-1.0mm 80mm wide, 800 -1.0mm
For paper 60mm wide, 600
-1.0mm 58mm wide, 580 -1.0mm
- Outside diameter: For paper 75 to 90µm thick, φ102mm or less
For paper 90 to 150µm thick, φ90mm or less
- Core diameter: For paper 75 to 90 µm thick, φ12±0.5mm (inside)
/φ18±0.5mm (outside)
For paper 90 to 150µm thick, φ25.4±0.5mm (inside)
/φ32±0.5mm (outside)
- Printed surface: Outside of the roll
- Treatment of end of paper: The roll paper must not be glued to the core. The

Note: A recommended type of paper must be used. If a type of paper other than a
recommended one is used, head damage, printing irregularities, or similar
problems may occur.
Note: To use two-color thermal paper, set the print color to two colors from the
printer setup menu or using the setup tool contained on the CD-ROM
provided with the printer.
(See "C-3 Setting Up the Printer" in Appendix C, "Special Modes.")
* By setting the appropriate property (use Color on the Graphics tab) for
printing with this printer driver, you can easily print in two-color mode
without having to change the printer setup.
Note: Ruled lines or characters containing fine lines (e.g. a serif typeface) tend to
have dull colors when they are printed on two-color thermal paper. For
printing on two-color thermal paper, a thick font (e.g., a sans serif font) is
recommended.

8
Note: Red or blue printing on two-color thermal paper has an inferior preservation
characteristic that is equivalent to that of normal thermal paper.
Note :Printouts on label paper or thick paper may contain blurs or voids, depending
on the humidity and other environmental conditions. Adjust the print speed
and print density as appropriate for the type of paper used. (See "C-3 Setting
Up the Printer" in Appendix C, "Special Modes.")
In particular, note that the paper transport accuracy may be negatively
affected by printing a barcode in the top margin at the beginning of paper
transport or in the Lower margin at the end of paper transport.

3. Preparations
No printer cable is provided with the product. Obtain a printer cable
suitable for the product interface. If you have any questions, consult your
dealer. Before connecting or disconnecting cables, make sure of the
following:
1) The power to the printer and all other devices connected to the
printer is turned off.
2) The AC adapter power cable has been unplugged from the outlet.
3-1. Connecting Interface Cable
Open the connector cover at the rear of the printer by pulling it up, and
connect the interface cable to its rear connector socket. Close the cover after
connecting the cable.
Note: If cables are arranged so that they extend from the rear or from the rear on the
right side, remove the inserts in the connector cover or the cover with nippers
or a similar tool. Unless the inserts are removed in this case, the cables may be
damaged and cause a failure.

Caution: If the device is installed vertically, the LAN cable may not usable
due to its shape. Please check before installing.
Caution: The LAN interface cable must use the shield type.

3-2. Connecting the drawer kick cable
Open the connector cover at the rear of the printer by pulling it up, and
connect the drawer kick cable to its rear connector socket. Close the cover
after connecting the cable.
Note : If the cable is arranged so that it extends from the rear, remove the inserts
in the connector cover with nippers or a similar tool. Unless the inserts are
removed in this case, the cable may be damaged and cause a failure.
Note : The drawer kick cable must not be used for a purpose other than for control
of the drawer.

3-3. Connecting the AC Adapter
(1) Connect the AC adapter to the AC adapter power cable.
Note: To connect or disconnect the AC adapter, turn off the power switches of the
printer and all the devices to be connected to the printer. Then, unplug the
plug of the AC adapter power cable from the electrical outlet.
Note: Use only the specified AC adapter and specified AC adapter power cable.
(2) Open the connector cover at the rear of the printer by pulling it up, and
connect the AC adapter cable to the power socket.
Close the cover after connecting the cable.
Note: To connect the AC adaptor, place the printer on its side to make the
connection operation easier to perform.
Note: Remove notch of connector cover with Nipper, to maintain the space for the
cable of AC adapter.
Otherwise, the cable may be damaged and it way cause a failure.

Note: To prevent the adaptor from slipping out, the connector section is
designed to be tight to fit. When inserting, (1) pinch the base of the cable,
(2) while sliding the outer section of the connector upwards, (3) and
insert the connector until it locks in place with a “click” sound.
(3) Connect the plug of the power cable to electrical outlet.
(4) Plug the other end of the power cord into the power outlet.

3-4. Disconnecting the AC Adapter
To unplug the AC adapter cable, grasp the connector as shown in the
picture below and pull it out. The lock mechanism of the connector will
then disengage, and the cable can be unplugged easily. Conversely,
forcibly pulling on the cable itself may damage the connector.
Note: Before disconnecting the AC adapter, switch off the printer and all devices
connected to the printer, and also disconnect the power cable of the AC
adapter from the outlet.

17
3-5. Turning on the Power
After the AC adapter is connected, turn on the power switch at the side of
the printer. The POWER lamp on the control panel lights.
3-6. Installing the Printer Software
Referring to the "Installation Guide"
(\Manuals\PT390_InstallGuide1_en.pdf) contained on
the CD-ROM provided with the printer, install the printer driver and
utility software.

4. Inserting Paper for Printing
4-1. Replacing paper
(1) Grasp the top cover, pull up the cover release lever, and
open the top cover.
(2) When manipulating the top cover, note that the cover seems to
lock in position before it is open completely. Make sure that the
cover is really open completely as shown in the picture below.
Note: If the top cover is not open completely during maintenance, it may close
inadvertently.
