Key to Symbols

The following symbols are used in the documentation for this product. See the specific warnings and cautions at appropriate points throughout this guide.

WARNING:

Warnings must be followed carefully to avoid serious bodily injury.

CAUTION:

Cautions must be observed to avoid minor injury to yourself, damage to your equipment, or loss of data.

Note:

Notes have important information and useful tips on the operation of the product.

Safety Precautions

This section presents important information to ensure safe and effective use of this product. Please read this section carefully and store it in an accessible location.

WARNING:

❏ Turn off the power switch immediately and unplug the power cord from the electrical outlet

if the TM-U230 produces smoke, a strange odor, or unusual noise. Continued use may lead to fire or electric shock.

❏ Do not modify the printer or perform any disassembly operation not described in this

manual. Doing so could result in a fire or shock hazard.

❏ Use only the designated power supply. Use of a different power supply could cause a fire or

shock hazard.

❏ Never insert or disconnect plugs with wet hands. Doing so may cause a serious shock.

❏ Never drop or push objects into the product through openings. This could cause a fire or

shock.

❏ If the printer is exposed to water or other liquid, turn off the POWER button and disconnect

the power cord immediately. Continued use under these conditions could cause a fire or shock hazard.

❏ Do not connect the power cord to an overloaded wall outlet. This may cause a fire hazard.

Connect the printer directly to a wall outlet.

❏ Handle the power cord with care. Incorrect handling may lead to fire or shock.

Confidential

• Do not modify the power cord.

• Do not place heavy objects on the power cord.

• Do not bend, twist, or pull the power cord excessively.

• Do not route the power cord near heaters.

• Remove any dirt or dust from the power plug before plugging it in.

• Be sure to fully insert the power plug.

TM-U230 Developer’s Guide

CAUTION:

❏ All cables are to be connected only as described in the manual. Incorrect connection could

cause damage or a fire hazard.

❏ Be sure to set this product on a firm, stable, horizontal surface. The product may break or

cause injury if it falls.

❏ Do not install the printer in extremely humid or dusty locations. Operation under such

conditions could damage the printer or cause a fire or shock hazard.

❏ Do not stand on the printer or place heavy objects on it. The printer could fall or collapse,

causing breakage and possible injury.

❏ For added protection of the printer, disconnect the power plug from the wall outlet when

the printer is not to be used for an extended period of time.

❏ Be sure not to touch the print head or motors when you remove paper jammed in the

printer. Wait until the print head and motors have cooled down before removing jammed paper. When the printer has been used for an extended period, the print head and the motors are very hot and could cause burns.

Precautions in handling the fine coating of the case (only for fine coating case model)

A fine coating is used for the external surface of the plastic case of the printer, which makes wiping and removing kitchen stains easy; however, you should note the following when cleaning the surface in order to preserve the quality of the coating (the metal plate and the inside of the case do not have the fine coating):

❏ Do not scrub the surface with a hard object. Otherwise, the case will be scratched and harder

to clean.

❏ Do not use a cleanser that includes polishing materials such as grains of glass, metal, or

ceramics. Otherwise, the case will be scratched and harder to clean.

❏ Never use disinfectant, bleach, alcohol, benzine, thinner, chlorine solvent, or ketone solvent.

Otherwise, the case will be harder to clean, and the case may be seriously harmed or even deformed and its color may be changed.

❏ The label may come off of the fine coating of the case if harsh cleaning methods are used.

Precautions in Handling the Fine Coating Case (only for Fine Coating Case model)

This printer is housed in a plastic case (*) with a fine coating; simple cleaning is enough to enable dirt to come off easily so that the exterior of the printer remains in good condition. Like plastic cases, handle the fine coating with care as described below.

(*)Fine coating is not applied to the installation surface of the metal plate, the power supply box

and the inside of the case.

• Do not scratch the surface with hard objects; otherwise the case may become damaged and dirt may become difficult to remove.

• Do not use any type of abrasive agent (glass, metal, ceramic, etc.) to clean the case; otherwise the surface of the case may become damaged and dirt may become difficult to remove.

• Never clean the case with disinfectant, bleach, alcohol, benzene, thinner, chlorine, or ketone; otherwise the dirt may become difficult to remove. Also, they may cause the case to become discolored, dissolved, or deformed.

• Label may come off of the fine coating of the case.

Selecting a Place of Installation

This printer can be installed vertically (standard installation) so that the paper exit faces the front or horizontally so that the paper exit faces upwards. With the optional wall mounting bracket (Model No: WH-10) the printer can be wall-mounted.

Note:

Since vibrations are generated during paper cutting, take suitable measures to secure the printer.

❏ Installation on a table (vertical or horizontal installation)

• Regardless of installation method chosen, the tilt of surface selected must be 15° or less.

• Attach the supplied switch panel sheet for horizontal installation when the printer is to

be installed horizontally.

• Adjust the N.E detector and attach the rubber feet as required by the chosen method of installation.

Attaching the Power Supply Box (only for models with exclusive power supply unit)

The location of the power supply box varies with the method of installation.

WARNING:

Use only AC adapter designated by EPSON. Using a non-standard power supply may cause a fire or shock hazard.

When you are using an EPSON AC power supply or the equivalent, immediately turn off the printer and disconnect the power plug when you notice an abnormality.

CAUTION:

Always disconnect the power plug from the wall outlet when connecting or disconnecting the AC adapter. Otherwise you may damage the AC adapter or the printer.

Make sure that the rated voltage of the AC adapter matches the voltage of the wall outlet before connecting the AC adapter. Do not plug in the AC adapter if the voltages do not match. Otherwise you may damage the AC adapter or the printer.

Note:

To remove the DC cable connector, make sure the power supply power cord is unplugged; then grasp the connector at the arrow and pull it straight out.

Assembling the Power Box

1. Place the AC adapter in the upper adapter cover. Bundle up the DC power supply cable. Be sure that the power receptacle is against the rectangular hole in the power supply box.

Waterproof

The TM-U230 is designed as a kitchen printer with protection from water. When it is installed vertically or horizontally, the printer meets the European Standards IEC 529 for protection against water of "keeps out water coming from an angle up to 15 level. (The TM-U230 also meets the IEC Standards for protection from tools and thin wires with a diameter more than 2.5 mm and protection from solid foreign objects with a diameter greater than 2.5 mm.) The IP code of the TM-U230 when it is installed vertically or horizontally is IP32. The meaning of the "IP" numbers is described in the next section of this manual.

TM-U230 Developer’s Guide

The ability of an enclosure to keep out dirt and water is defined in IEC 529. When an enclosure protects the equipment from water and particles of dirt, it also protects people from any potential hazard inside the equipment.

The degree of protection is designated by the letters "IP" followed by two digits such as "IP01" or "IP34." The first digit indicates the degree that the equipment is protected from solid foreign objects. The second digit indicates the degree that the equipment is protected from water. The details are described in the tables below. The first digit, protection from solid foreign objects, is divided into "protection from human contact" and "protection from foreign bodies."

4. Execute GS V 98 0

5. Print receipt C

6. Execute GS V 98 0

If the cutting ranges designated in step 4 and 5 have not reached the autocutter position, Receipt B and C will not be cut. Even if they have reached the autocutter position and have been cut, the receipts do not reach the paper exit. With this condition, if the next printing is not performed, Receipts B and C will not be ejected. Therefore, be sure to take the following into consideration.
