Power Switch Cover

Install the power switch cover that comes with the TM-T88IV 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)

into the hole in the power switch cover and press the power switch.

POWER LED (green)

•Lights when the power supply is on.

•Goes out when the power supply is turned off.

ERROR LED

Lights or flashes when the printer is offline.

•Lights after the power is turned on or after a reset (offline). Automatically goes out after a

while to indicate that the printer is ready.

•Lights when the end of the roll paper is detected, and when printing has stopped (offline). If

thi

s happens, replace the roll paper.

•Flashes when an error occurs. (For details about the flash codes, see "Error Status" on page 19.)

•Goes out during regular operation (online).

WARNING

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

immediately.

Continued use may cause fire or shock.

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

y paper supply is detected by

the roll paper end sensor or if the driver has been set to stop printing when a roll paper near-

end is detected)

•When an error has occurred

The picture above shows a serial interface model. For details on the various interfaces and

how to connect the power supply connector and cash drawer, see "Connecting the Printer

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 can be

recovered easily, as described below.

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.
