1 Power Switch
Turns the printer on or off. The marks on the switch: ( : OFF/ : ON)
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 Quick Reference or the
ESC/POS Application Programming Guide.
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
A waterproof cover for the power switch is also included.
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.

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
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. Even with a serial
interface model whose communication speed is low, high speed graphic printing is possible.
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 con
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 71.
firm the registered graphics.
User NV Memory
Yo u 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.
For information about ESC/POS commands, see the ESC/POS Quick Reference or the
ESC/POS Application Programming Guide.
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 43.
20
Chapter 1 Product Overview
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 43.
User-defined Page
Yo u 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 68.) and the TM-T20 Utility.

*: when the printer prints with the standard print density level at 25°C {77°F}.
To change the paper width, you need to install the 58-mm width paper guide plate and to
make the paper width setting with the memory switch. For information about how to
change the paper width, see "Changing the Paper Width" on page 36.
Because some parts of the print head and the autocutter contact the platen and they
may become worn out, once you change the paper width from 80 to 58 mm and use the
printer, you cannot change it back to 80 mm.
Printing speed may be slower, depending on the such items as the data transmission
speed.

Note on printing with a high print ratio
If printing is continuously performed with a high print ratio, the overcurrent protection may be
activated and result in uneven print density or a low voltage error. Therefore, the printing length
must not exceed the following values when printing with high print ratio.
Print ratio: Number of dots being e
nergized per one dot line / Total number of dots per one
dot line (576 dots)
