Power Switch Cover

Install the power switch cover that comes with the TM-T70 onto the printer to prevent

inadvertent changing of the power switch, to prevent tampering, and to improve the appearance

of the printer.

To reset the printer when the power switch cover is installed, insert a long, thin object (such as

the end of a paper clip)

Offline

The printer automatically goes offline under the following conditions:

•During power on (including resetting with the interface) until the printer is ready

•During the self-test

•While roll paper is fed using the FEED button.

•When the printer stops printing due to a paper-end (if an empt

Error Status

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

unrecoverable errors.

Automatically Recoverable Errors

Printing is no longer possible when automatically recoverable errors occur. They c an be

recovered easily, as described below.

Error LED flash code

Error Error description

Approx. 160 ms

Roll paper cover open error

Print head temperature error

The roll paper cover was opened during printing.

A high temperature outside the head drive operating range was detected.

Recovers automatically when the roll paper cover is closed.

Recovers automatically when the print head cools.

Recoverable Errors

Printing is no 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.

Autocutter error Autocutter does not

work correctly.

Approx. 160 ms

Approx.2.56 s

Recovery measure

Remove the jammed paper or foreign matter in the printer, close the roll paper cover, send the error recover command, or turn the power on to recover.

The error recovery command is valid only if a recoverable error (excluding automatically recoverable errors) occurs.

Chapter 1 Product Overview

Unrecoverable Errors

Printing is no longer possible when unrecoverable errors occur. The printer must be repaired.

Turn off the power immediately when unrecoverable errors occur.

CAUTION

High voltage error The power supply voltage is extremely

high.

Low voltage error The power supply voltage is extremely low.

Approx. 160 ms

CPU execution error The CPU is executing an incorrect address.

Internal circuit connection error

UIB error An abnormal operation occurs in UIB.

Internal circuits are not connected correctly.

Approx.2.56 s

NV Memory (Non-Volatile Memory)

The printer has NV memory which includes the user NV memory and NV graphics memory that

users can use.

NV memory can be rewritten about 100,000 times. As a guide, NV memory rewriting should be 10 times or less a day when you program applications.

CAUTION

User NV Memory

Characters can be stored in the user NV memory.

Use ESC/POS commands to write or read them.

For detailed information about ESC/POS commands, see the ESC/POS Application Programing Guide.

NV Graphics Memory

Graphics such as shop logos to be printed on recei pts can be stored. Even with a serial interface

model whose communication speed is low, high speed graphic printing is possible.

Use the TM Flash Logo Setup utility for NVRAM to register graphics.

NV Graphics Print Mode

In this mode the printer prints the following:

•Capacity of the NV graphics

•Used amount of the NV graphics

•Unused capacity of the NV graphics

•Number of the NV graphics that are registered

• Key code, number of dots in X direction, number of dots in Y direction, number of colors to be

defined.

•NV graphics dat
