Chapter 1 Product Overview

NV Memory (Non-Volatile Memory)

The printer's NV memory stores 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

 Maintenance counter

As a guide, NV memory rewriting should be used 10 times or less a day when you program applications.

NV Graphics Memory

Graphics, such as shop logos to be printed on receipts, can be registered.

You can also use the NV graphics information print mode to print and confirm the registered graphics.

For information about how to use the NV graphics information print mode, see "NV Graphics

Information Print Mode" on page 57

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

With the memory switches, which are software switches for the printer, you can configure various settings of the printer. For information about the memory switch, see

"Software Settings" on page 43.

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 printer's memory. You can read the counter information to use it for periodical checks or part replacement.

You can also check the head running length and number of times of autocutting with the self-test (see "Self-test Mode" on page 57).

Simple Setup for Wireless LAN

This printer comes with a mode (SimpleAP) that allows printers to connect with a smart device or a computer without requiring a wireless access point. This allows you to easily setup a wireless LAN for the printer by using a printer settings tool (Epson TM Utility, EpsonNet Config, or EpsonNet Config (Web version)) even without a network environment such as access points.

SimpleAP mode is enabled by default when shipping from the factory. When SimpleAP mode is enabled and the printer is turned on, the following information is printed automatically.

Chapter 1 Product Overview

Useful Functions for Smart Devices

You can easily connect this product to the network by using the NFC tag built-in to the printer or the QR code printed on the status sheet.

NFC Tag

Bring a smart device that supports NFC close to the NFC tag to acquire the printer information (information for specifying the device).

Specify the target printer using the acquired information to connect to the network.

QR Code

Capture the QR code printed on the status sheet with the camera on your smart device to acquire the printer information (information for specifying the device).

Specify the target printer using the acquired information to connect to the network.

 Programming using Epson ePOS SDK is required to use these functions. These functions are

created by combining NFC touch and QR code capturing operations and the target printer specifications using Printer Easy Select API. See the "Epson ePOS SDK for Android/iOS User's Manual" and the Epson ePOS SDK sample program for more details. The sample program also contains a sample implementation method for reading an NFC tag and capturing a QR code.

 You can try a demo of these functions by using Epson TM Utility for iOS/Android.

Printing Using Multiple Interfaces

In models with multiple interfaces, you can use all interfaces without any limitations on which interface is to be used. You can use this function to temporarily connect a smart device to a nearby printer and print.

The printer provides each interface with an independent receive buffer and switches the active interface depending on the priority, while handling data in each receive buffer.

You can set one interface for the main connection. Data received from the main connection interface is handled with the highest priority.

By default, the interface that receives the first data transfer is set as the main connection interface; however, you can select the main connection interface in advance.

In the status where all receive buffers are empty for more than the set time (1 second by default), interface switching is enabled. The interface that receives the data in this status becomes active.

You can select the main connection interface and set the time to enable interface switching from the software settings. For details on software settings, see "Software Settings" on page 43.

Flow of Setup

This chapter consists of the following sections along with the setup flow of the product and peripherals.

Chapter 2 Setup

Installing the Printer

You can install the printer on a flat surface with the paper eject from top or with the paper eject from the front.

Place the printer on a flat surface.

Top eject position

Front eject position

 Take measures to prevent the printer from moving due to vibrations when using the cash drawer.  Do not place the printer in locations subject to high dust levels.  Do not give a high impact on the printer during operation. Doing so may cause the print failure.  Be careful not to place cords or foreign substances under the printer.

You can install the printer as a wall hanging printer if you use the optional Wall Hanging Bracket Set (OT-WH30). Refer to the installation manual of the Wall Hanging Bracket Set for details.

Chapter 2 Setup

Changing to the Front Eject Position

You can change the eject position by replacing the rear cover and the bottom cover. At the time of purchase, paper is ejected from the top position. When changing to the front eject position, follow the steps below to replace the covers.

Remove the bottom cover and the rear cover.

See the detail information on "For the top eject position" on page 85.

Attach the rear cover and the bottom cover.

See the detail information on "For the front eject position" on page 88.

Changing the Paper Width

You can change the paper width from 80 to 58 mm by installing the included 58-mm width roll paper guides. Follow the steps below to change the paper width.

Turn off the printer when installing the roll paper guides.

Open the roll paper cover.

Align the three projections on the roll paper guides with the slots (*) in the printer,

and then press them down.

Chapter 2 Setup

After using the printer for an extended period at 58 mm, do not return to 80 mm. Parts of the print head that do not normally touch the paper may be damaged by the platen roller, and the autocutter may wear out.

Set the paper width in software setting mode.

For information about the software setting mode, see "Software Settings" on page 43.

Connecting to the Power Source

AC cable

AC adapter

 Be sure to use the specified AC adapter only.  Never insert the AC cable plug into a socket that does not meet the input voltage of the AC

WARNING

Connecting the AC cable

Make sure the printer is turned off.

Connect the AC cable to the AC adapter.

adapter.

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 socket.

Use the AC cable provided with this printer.

Connect the DC cable of the AC adapter to the power supply connector.

When charging smart devices or USB devices with Onboard USB Powers Tablet

model, connect the cable to the USB connector for charging.

Chapter 2 Setup

 Make sure you use the genuine cable for the tablet, smartphone, or USB device you are

using.

 Depending on how the device is being used, it may not charge to 100%.  It may take a few seconds before charging starts as the device searches for the most

suitable amperage.

 Charging may not be performed depending on the device's charging specifications.  Charging stops if it exceeds the rating for the USB connector.  It may be hard to disconnect some types of USB cable. Do not forcibly pull the cable, or the

USB connector and USB cable may be damaged. Contact your dealer if you encounter the trouble.

Insert the AC plug into a socket.

Turn on the printer.

Connecting the Printer to the Host Devices

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.

Do not place any weight or stress on the cable when using. Doing so could damage the cable and connectors.

Ethernet Interface

Use ethernet cable to connect the printer to network via a hub.

Use EpsonNet Config, EpsonNet Config (Web version), or arp/ping commands to set network.

For information on setting up network, see

Wireless LAN Interface

"Network Settings" on page 51.

Using Epson TM Utility, you can easily connect the printer to the network from an iOS or Android devices. We also recommend connecting the SimpleAP from a Windows computer, and setting up the Wireless LAN using the network setup tool (EpsonNet Config or EpsonNet Config (Web version)).
