Chapter 1 Product Overview
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 (Customized value)
•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
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-T20III Utility or ESC/POS commands can be used for the graphic registration. TM-T20III Utility or NV Graphics Information Print Mode can be used for the confirmation.
You can store and read text data for multiple purposes, such as for storing a note including customizing or maintenance information of the printer.
You can configure various settings of the printer.
For more information, see "Software Settings" on page 42.
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-T20III Utility or ESC/POS commands can be used for the settings.
TM-T20III Utility or Receipt Enhancement Information Print Mode can be used for the confirmation.

Chapter 1 Product Overview
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.
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 autocutting with the self-test (see "Self-test Mode" on page 53).
•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.

Chapter 1 Product Overview
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 (TM-T20III Utility, 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.

Although operations are performed in SimpleAP mode during the initial startup, operations switch to standard mode (infrastructure mode) when changing settings in Epson TM-T20III Utility or EpsonNet Config. After switching, operations continue in standard mode. If you want to make settings in SimpleAP mode again, initialize the communication settings. ("Resetting the Interface Settings" on page 62)

Chapter 1 Product Overview
You can easily connect this product to the network by using the QR code printed on the status sheet.
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.
• To use the function, programming using Epson ePOS SDK is required. In addition to the QR code capturing operations, use Printer Easy Select API to achieve this function.
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 capturing a QR code.
• You can try a demo of the function by using Epson TM Utility for iOS/Android.

Chapter 2 Setup
You can install the printer horizontally on a flat surface (with the paper exit on top) or vertically (with the paper exit at the front). Also, you can hang it on a wall using the included accessories.
Horizontal installation |
Vertical installation |
Hanging on a wall |
•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.
When installing the printer vertically, attach the four rubber feet in the rectangular indents in the printer case, as shown in the illustration below.

Chapter 2 Setup
To securely hang the printer on a wall, follow the steps below.
•Hang the printer on a wood, concrete, or metal wall. The thickness of the wall should be 10 mm {0.4"} or more.
•Be sure to use metallic screws.
•The screws to be put into the wall must have a pull-out strength of 150 N (15.3 kgf) or more.
1 Put two screws (diameter: 4 mm {0.16"}, head diameter: 7 to 9 mm {0.28 to 0.35"}) into the wall at an interval of 80 mm {3.15"}.
Make sure the length of the screw in the wall is 10 mm {0.39"} or more, and the length outside the wall is 3 to 4 mm {0.12 to 0.16"}.

Chapter 2 Setup
Below are two situations where a roll paper near-end 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.
•The roll paper near-end detection function can be used only when this product is installed horizontally.
•Be sure to disable the near-end detection when the product is installed vertically or is wallmounted. Failure to do so may lead to erroneous detection.
•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 near-end sensor can detect the remaining paper as accurately as possible.
•To use the near-end detection, it must be enabled using the memory switches. See "Software Setting Mode" on page 54 for details about the making the memory switch settings.
Follow the steps below to adjust the roll paper near-end sensor.
1Open the roll paper cover, and remove the roll paper.
2Loosen the adjustment screw fastening the sensor, and align the upper edge of the positioning plate with the adjustment position.

• Be sure to use the specified AC adapter [AC adapter, C1 (Model: M235B)]. Penetration by foreign objects may lead to fire.
WARNING |
• Never insert the AC cable plug into a socket that does not meet the input voltage of the AC |
|
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 wall socket. |

Chapter 2 Setup
•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.
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 hook to prevent it from being disconnected.
Hooks
USB cable
Do not place any weight or stress on the cable when using. Doing so could damage the cable and connectors.
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.
•When using interface cables equipped with a ground line, attach the ground line to the screw hole marked “FG” on the printer.
