Printer Status

NOTE:

The printer enters this status while processing the power off command. It is recommended to use this method when you need to save information on the printer’s operating status if the power is cut without using the power switch.

*1: The Error LED flashing pattern is: turning on and off alternately at 320 ms intervals for five seconds, then goes off. *2: The Power LED flashing pattern is: lighting for 320 ms followed by a pause for 320 ms. *3: 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.

• TM-Intelligent function error The printer recovers from the error when the printer settings are corrected.

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.

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 48.

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.

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 64).

• The main 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.

tenance counter values are automatically saved in the NV memory usually every two

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.

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).

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 48.

• 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.

• When you have set the printer to eject printed paper from the front side, you can flip printed pages upside down by enabling the "Batch rotate print (Upside Down)" function. For more details, see "Software Settings" on page 48.

Chapter 2 Setup
