Chapter 1 Product Overview
NV Memory
The printer's NV memory (Non-Volatile 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
• R/E (Receipt Enhancement)
• Maintenance counter
• Web contents
NV memory can be rewritten about 100,000 times. As a guide, NV memory rewriting should be 10
times or less a day when you program applications.
CAUTION
1
NV Graphics Memory
Graphics, such as shop logos to be printed on receipts, can be stored.
To register your graphics data, use TM-T88VI Utility or ESC/POS commands.
You can check registered graphics data using TM-T88VI Utility or by printing the data in the NV graphics
information print mode.
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 54.
R/E (Receipt Enhancement)
You can set the graphics data, such as a shop logo, registered in the NV graphics memory to be printed on the
top of each receipt or to be printed on the bottom of each receipt just before the paper is cut.
To make the settings, use TM-T88VI Utility or ESC/POS commands.
You can check the settings using TM-T88VI Utility or by printing the settings information in the Receipt
enhancement information print mode.
23
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 also check the head running length and number of times of autocutting with the self-test
(see
"Self-test Mode" on page 68).
• The maintenance counter values are automatically saved in the NV memory usually every two
minutes (up to four minutes). However, the values are not saved when the printer is in
power-saving mode or when it is turned off without the use of the power switch.

Chapter 1 Product Overview
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 for iOS/Android or EpsonNet Config) 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.

SimpleAP Start

IP Address
MAC Address
Although operations are performed in SimpleAP mode during the initial startup, operations switch to standard
mode (infrastructure mode) when changing settings in Epson TM-T88VI Utility for Windows or EpsonNet
Config. After switching, operations continue in standard mode. If you want to make settings in SimpleAP mode
again, initialize the communication settings. (see

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.
26
Chapter 1 Product Overview
Printing Using 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 cannot use wired and wireless LANs at the same time. When a LAN cable is connected, wireless
LAN is disabled.
1
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 54.

Below are two situations where a roll paper NE sensor adjustment is required.
• To adjust the detection position to suit the diameter of the roll paper core used.
• To adjust the detection position of remaining amount of paper.
• Since roll paper cores vary slightly in shape, depending on paper roll design and manufacturing
tolerances, it is impossible to detect the remaining paper exactly.
• Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm {0.71"} so
that the NE sensor can detect the remaining paper as accurately as possible.
Follow the steps below to adjust the roll paper near-end detector.
Open the roll paper cover, and remove the roll paper.
1
Loosen the adjustment screw fastening the sensor, and align the upper edge of the
