Chapter 1 Product Overview
NV Memory
The printer is equipped with the NV memory (Nonvolatile Memory) to store data even after the printer power
is turned off. NV memory contains the following memory areas for the user:
• NV graphics memory
• User NV memory
• Memory switches
• R/E (Receipt Enhancement)
• User-defined page
• Maintenance counter
As a guide, NV memory rewriting should be 10 times or less a day when you program applications.
CAUTION
NV Graphics Memory
Graphics, such as shop logos to be printed on receipts, can be stored. Even with a serial interface model whose
transmission speed is low, high speed graphics printing is possible.
TM-T82X Utility or ESC/POS commands can be used for the graphic registration.
TM-T82X Utility or NV Graphics Information Print Mode can be used for the confirmation.
User NV Memory
You can store and read text data for multiple purposes, such as for storing a note including customizing or
maintenance information of the printer.
Memory Switches (Customized Value)
You can configure various settings of the printer. For more information, see "Software Settings" on page 26.
R/E (Receipt Enhancement)
Registered graphics in the NV Graphics Memory can be printed automatically, as a top logo before receipt
printing or as a bottom logo before cutting paper.
TM-T82X Utility or ESC/POS commands can be used for the settings.
TM-T82X Utility or Receipt Enhancement Information Print Mode can be used for the confirmation.
17
Chapter 1 Product Overview
User-defined Page
You can store character data in the user-defined page (character code table: page 255) so that you can also print
characters not resident in the printer.
Maintenance Counter
With this function, printer information, such as the number of lines printed, the number of autocuts, and
printer operation time after the printer starts working, is automatically stored in NV memory. You can use the
counter information for periodical checks or part replacement.
• You can also check the print head running length and number of times of auto-cutting with the
self-test (see
• The maintenance counter value is normally saved in the NV memory every 2 minutes (maximum
of 4 minutes). However, it is not automatically saved when the product is in the power-saving
mode or when the power is turned off without using the power switch.
"Self-test Mode" on page 36).

Installing the Printer
Wire saddle
USB cable
Observe the following precautions when installing the printer.
• The printer must be installed horizontally.
• Do not place the printer in a dusty location.
• Do not knock or strike the printer. This may cause defective print.
• Do not catch cables or place foreign matter under the printer.
• Take measures to prevent the printer from moving by vibration during paper cutting and when using a
drawer. Affixing tape (Model: DF-10) is provided as an option.
Connecting the Printer to the Host
• Be sure to install the driver before connecting the printer to the host computer.
• The printer uses a modular connector specifically designed for the cash drawer. Do not connect
the connector to an ordinary telephone line.
Chapter 2 Setup
USB Interface
When using USB cable to connect with host device, connect the USB cable to the printer, and after starting the
host device, turn the printer on.
When connecting the USB cable to the printer, fix the cable with the wire saddle to prevent it from being
disconnected.
Do not place any weight or stress on the cable when using. Doing so could damage the cable and
connectors.
20
Chapter 2 Setup
Serial Interface
When connecting to the host computer through a serial interface (RS-232), connect a serial cable to the printer,
start the host computer, and then turn on the printer.
When using connectors equipped with screws, tighten the screws on both sides to secure the
connectors firmly.
Ethernet Interface
Use an Ethernet cable to connect the printer to network via a hub.
Use Epson TM-T82X Utility or EpsonNet Config to set network.
For details on Epson TM-T82X Utility, refer to TM-T82X Utility User's Manual.
For details on EpsonNet Config, refer to EpsonNet Config User's Guide.
• When LAN cables are installed outdoors, make sure they are connected through devices that
have surge protection.
Otherwise, the devices can be damaged by lightning.
• Never attempt to connect the drawer kick cable or a standard telephone line cable to the LAN
connector.
As same with Conventional models, you can use EpsonNet Config (Web version) in the same way.
Start up a web browser and then input the printer's IP address in the address bar.
On the authentication screen, input your user name and password.
The default setting for the password varies depending on the firmware version.

• Never insert the AC cable plug into a socket that does not meet the rated voltage requirements
of the printer.
WARNING
Be sure to use the included AC cable.
Connecting Procedure
Make sure the printer is turned off.
1
Connect the AC cable to the power supply connector.
2
Doing so may result in damage to the printer.
• Should a fault ever occur, immediately turn off the power to the printer and unplug the AC cable
from the wall socket.

Connecting the Cash Drawer
• The optional external buzzer and the cash drawer cannot be used simultaneously. Do not
connect both the optional external buzzer and the cash drawer to the printer at the same time
by using a branched connector.
• The cash drawer cannot be used If the enable/disable setting for the optional external buzzer is
set to “enable”. When using the cash drawer, be sure to set it to “disable” using the Epson TMT82X Utility.
• Two driver transistors cannot be energized simultaneously.
• Leave intervals longer than 4 times the drawer driving pulse when sending it continuously.
Cash Drawer Requirements
Specifications of drawers differ depending on makers or models. When you use a drawer other than specified,
make sure its specification meets the following conditions.
Otherwise, devices may be damaged.
• The load, such as a drawer kick solenoid, must be connected between pins 4 and 2 or pins 4 and 5 of the
drawer kick connector.
• When the drawer open/close signal is used, a switch must be provided between drawer kick connector pins 3
and 6.
• The resistance of the load, such as a drawer kick solenoid, must be 24 ohms or more or the input current
must be 1A or less.
• Be sure to use the 24V power output on drawer kick connector pin 4 for driving the equipment.
