CAUTION
Before turning on the printer, be sure to check that the AC adapter is connected to
the power supply.
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.)

Power Switch Cover
Install the power switch cover thatcomes 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 resetthe printer whenthe power switch cover is installed, inserta long, thin object(such as
the end of a paper clip) into the hole in the power switch cover and press the power switch.

Connectors
All cables are connected to the connector panel onthe lower rear of the printer.
• Drawer kick-out connector: Connects the cash drawer.
•Powersupply connector: Connects the power supply unit
•Interface connector: Connects the printer with the hostcomputer interface.
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.
•Whenthe printer stops printing due to a paper-end (if anempty paper supply is detected by
the roll paper end sensor or if the driver has beensetto stop printing whena roll paper near-
end is detected)
•Whenanerror has occurred
The picture above shows a serial interface model. For details on the various interfaces and

Error Status
There are three possible error types: automatically recoverable errors, recoverable errors, and
unrecoverable errors.
Automatically Recoverable Errors
Printing is no longer possible whenautomatically recoverable errors occur. They canbe
recovered easily, as described below.
Recoverable Errors
Printing is no longer possible whenrecoverable errors occur. They canbe recovered easily by
turning the power onagain or sending anerror recovery command from the driver after
eliminating the cause of the error.

NV Memory (Non-Volatile Memory)
The printer has NV memory which includes the user NV memory and NV graphics memory that
users canuse.
User NV Memory
Characters canbe stored in the user NV memory.
Use ESC/POS commands to write or read them.
NV Graphics Memory
Graphics such as shop logos to be printed onreceipts canbe stored. Evenwith a serial interface
model whose communicationspeed is low, high speed graphic printing is possible.
Use the TM Flash Logo Setup utility for NVRAM to register graphics.
NV Graphics Print Mode
Inthis mode the printer prints the following:
•Capacity of the NV graphics
•Usedamount of the NV graphics
•Unused capacity of the NV graphics
•Number of the NV graphics thatare registered
• Key code, number of dots in X direction, number of dots in Y direction, number of colors to be
defined.
•NVgraphics data
CAUTION
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.
For detailed information about ESC/POS commands, see the ESC/POS Application
Programing Guide.
