Part Names and Functions

1 Power Switch

Turns the printer on or off. The marks on the switch: ( : OFF/ : ON)

2 Power Switch Cover

Install the power switch cover that comes with the TM-T20 onto the printer to prevent

inadvertent operation of the power switch and to prevent tampering. To reset the printer when

the power switch cover is installed, insert a long, thin object (such as the end of a paper clip) into

the hole in the power switch cover and press

the power switch.

A waterproof cover for the power switch is also included.

Before turning the printer off, it is recommended to send a power-off command to the

printer. If you use the power-off sequence, the latest maintenance counter values are

saved. (Maintenance counter values are usually saved every two minutes.)

For information about ESC/POS commands, see the ESC/POS Application Programming

Guide.

WARNING

If an accident occurs with the power switch cover attached, unplug the AC cable

immediately.

Continued use of the printer may cause fire or shock.

Use the power switch waterproof cover if the printer is installed in a humid location or

exposed to water. If current leakage occurs, it could result in electric shock.

recovered easily, as described below.

Recoverable Errors

Printing is n o longer possible when recoverable errors occur. They can be recovered easily by

turning the power on again or sending an error recovery command from the driver after

eliminating the cause of the error.

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

•R/E (Receipt Enhancement)

•User-defined page

•Maintenance counter

NV Graphics Memory

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

Use the TM-T20 Utility to register graphics. You can also use the TM-T20 Utility or the NV

graphics information print mode to print and confirm the registered graphics.

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.

Use ESC/POS commands to store and read the text data.

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 "Setting the

Memory Switches/Receipt Enhancement" on page 39.

NV memory can be rewritten about 100,000 times. As a guide, NV memory rewriting should

be used 10 times or less a day when you program applications.

• For information about the TM-T20 Utility, see the TM-T20 Utility User’s Manual.

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

Graphics Information Print Mode" on page 62.

For information about ESC/POS commands, see the ESC/POS Application Programming

Guide.

20

R/E (Receipt Enhancement)

Graphics, such as shop logos can be printed on top or bottom of receipts by setting R/E (Receipt

Enhancement). For information about R/E, see "Setting the Memory Switches/Receipt

Enhancement" on page 39.

User-defined Page

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.

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 read the information with the Status API of the APD or OPOS ADK to use

it for per

iodical 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 59.) and the TM-T20 Utility.
