18

Chapter 1 Product Overview

Status and Errors

The status of the printer is indicated by lit and flashing LEDs.

You cannot print when an error has occurred.

You cannot identify the error by the flashing patterns of the LEDs. Develop the application so that users can identify the error description and check the solutions.

*1: Only the printers that are equipped with a roll paper near-end detector. To detect this status (remaining amount of roll paper is low), enable the "Roll paper near-end detection" function. For more details, see "Software Settings" on page 47. This function can be used only with a 80-mm width roll paper and only when the printer has been set up to eject printed paper from the front side. For more details about the restrictions, see "Enabling the Roll Paper Near-End Detection" on page 46.

*2: The Error LED flashing pattern is: lighting for 160 ms followed by a pause for 2400 ms. The LED goes off after repeating the pattern for five seconds.

*3: The Power LED flashing pattern is: lighting for 320 ms followed by a pause for 320 ms. *4: The Power LED flashing pattern is: lighting for 160 ms followed by a pause for 2400 ms.

Error Status

There are three possible error types: automatically recoverable errors, recoverable errors, and unrecoverable errors.

Automatically Recoverable Errors

•	Head temperature error	The printer recovers from the error when the head
		temperature drops.
•	Cover open error (in the middle of printing)	The printer recovers from the error when the roll paper
		cover is closed.

20

Chapter 1 Product Overview

Recoverable Errors

• Autocutter error			An error occurs if the cutter is locked due to fallen foreign material or
			similar cause. Although automatic recovery is performed even if there
			is only slight locking, if automatic recovery is not performed, remove
			foreign material and paper jams, and close the roll paper cover to
			perform recovery.
			Instead of closing the roll paper cover, you can make the printer recover from the error using a
			dedicated command, however, doing so will cause the printer to go offline due to a cover open
			error.

Unrecoverable Errors

•These include a high voltage error, CPU execution error, and communication unit error. If the error persists after turning the printer off and then on again, the printer may be defective. Contact qualified service personnel.

Turn off the power immediately when an unrecoverable error occurs.

21

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 (customized values)

•R/E (Receipt Enhancement)

•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.

To register your graphics data, use TM-m30II Utility or ESC/POS commands.

You can check registered graphics data using TM-m30II 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 (customized values)

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 47.

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-m30II Utility or ESC/POS commands.

You can check the settings using TM-m30II Utility or by printing the settings information in the Receipt enhancement information print mode.

22

Chapter 1 Product Overview

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 selftest (see "Self-test Mode" on page 63).

•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 powersaving mode or when it is turned off without the use of the power switch.

23

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, EpsonNet Config, or EpsonNet Config (Web version)) even without a network environment such as access points.

When the wireless LAN settings of the printer have not been changed from the factory default, and the printer is turned on, the printer automatically enters the Simple AP mode and prints the following information. If you have changed the wireless LAN settings from the factory default, start the printer according to the settings to connect the printer to an access point.

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).

By using the acquired information, the device can specify the printer to send a print job over a network or

Bluetooth.

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).

By using the acquired information, the device can specify the printer to send a print job over a network or

Bluetooth.

• 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.

Chapter 1 Product Overview

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.

When the receive buffer for the active interface becomes empty and a preset time period (one second by default) has passed, switching to another interface is enabled, and an interface that receives print data becomes active.

When you do not use the Bluetooth function, set the Bluetooth security level to "Middle" or "High" to prevent unauthorized access to the printer over Bluetooth. You can change the security level by

using Epson TM Utility, TM-m30II Utility, or in the Interface Setup mode.

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 47.
