Precautions When Installing the Power Supply Cover

A description of EMI standards is on the bottom of the printer. When the optional power supply cover (OT-BX88V) is installed, it is hard to check it. In such case, uninstall the power supply cover if necessary.

Part Names

Control Panel

(Power) LED
This LED is on when the printer is on.
Error LED
This indicates an error.
Paper LED
On indicates a paper near end or out. Flashing indicates standby.
Feed button
This button feeds paper.

Installing the Printer Horizontally or Vertically

You can install the printer horizontally on a flat surface (with the paper exit on top) or vertically (with the paper exit at the front) by hanging it on a wall, using the optional WH-10 hanging bracket set.

WARNING:
When hanging the printer on the wall with the hanging bracket set, be sure to attach a connector cover to the printer.

Setting Up the Printer

To set up the printer, follow the steps below.

1. Connect the cables.
2. Attach the connector cover.
3. Arrange the cables.
4. Install the roll paper.

Connecting the Cables

CAUTION:
For a serial interface, use a null modem cable.
For a parallel interface, use an IEEE 1284 cable.
For a USB interface, do not turn on the printer before installing the printer driver.

1. Make sure the printer is turned off.

2. Connect the power cord and each interface cable to the connectors on the printer back. For the shape of each connector, see the illustration below. (Mounted interfaces vary by the printer model.)
   

3. Connect the interface cable to the computer.

4. Insert the power cord plug into a socket.

Attaching the Connector Cover

Follow the steps below to attach the connector cover to protect the cables.

1. Turn over the printer.
2. Position the two hooks on both sides of the connector cover so that they hook the printer case.
3. Push the connector cover down to click onto the printer case.
   

To remove the connector cover, turn the printer over, and push the connector cover down while pushing both sides of the connector cover inward to detach the hooks from the printer case.

Arranging the Cables

Pass the cables through cable exits in the connector cover. The connector cover has cable exits on the back and both sides.
You can also route the serial, USB, or power cables out the front by passing them through the notch in the printer bottom.

If you want to pass the USB cable through the cable exit on the back, fit the cable under the hook on the printer to prevent the cable from coming off.

After the cable arrangement, turn over the printer, and make sure the cables are not pinched.

Installing Roll Paper

Follow the steps below to install the roll paper. If you want to change the paper width by using the roll paper guide, see “Changing the Paper Width” on page 11.

1. Press the cover open button to open the roll paper cover.

2. Remove the used roll paper core if any, and insert the roll paper. The correct direction of the paper is shown in the illustration below.
   

3. Pull out some paper, and close the roll paper cover.

4. Tear off the paper

Attaching the Power Switch Cover

The enclosed power switch cover ensures that the power switch is not pressed accidentally. You can turn on and off the power switch by inserting a sharppointed object in the holes in the power switch cover. To detach the cover, use a sharp-pointed object.

To use this cover, install it as shown in the illustration below.

WARNING:
If an accident occurs with the power switch cover attached, unplug the power cord immediately. Continued use may cause fire or shock.

Changing the Paper Width

If a roll paper guide is included with your printer, you can change the paper width from 80 mm to 58 mm by installing the roll paper guide. Follow the steps below to change the paper width.

CAUTION:
If you once change the paper width from 80 mm to 58 mm, you cannot change it back to 80 mm.
When changing the paper width, be sure to make the setting for the paper width with utility software for the TM-T88V.

1. Open the roll paper cover.

2. Install the roll paper guide so that the projection on its bottom is aligned with the hole at the right of the roll paper holder.

3. Tighten the enclosed screw to fix the roll paper guide.

4. Paste the enclosed 2 strips along the roll paper guide on the bottom of the roll paper holder. Make sure the space between the top edge of strip and the line of the groove in the roll paper guide (indicated as a in the illustration) is 0.5 mm or less.
   

5. Install the roll paper correctly.

6. Close the roll paper cover.

Troubleshooting

No lights on the control panel

Check whether the power supply cable is correctly connected to the printer and the socket.
Error LED on with no printing

• Check whether the roll paper cover is closed. If it is open, close it.
• If the Paper LED is on, check whether the roll paper is correctly installed and any roll paper remains.

Error LED flashing with no printing

• Check whether a paper jam has occurred. If paper is jammed, remove the jammed paper referring to the description below and install the roll paper correctly.
• Printing stops if the head overheats and resumes automatically when it cools.
• For other cases, turn the printer off, and after 10 seconds, back on.

Removing Jammed Paper

When a paper jam occurs, never pull out the paper forcibly. Open the roll paper cover and remove the jammed paper.

CAUTION:
Do not touch the thermal head and the frame on its side (indicated in the circle in the illustration below) because it can be very hot after printing.

If the roll paper cover does not open, follow the steps below.

1. Turn off the printer.

2. Slide the cutter cover toward the front to open it.

3. Turn the knob until you see a triangle in the opening. This returns the cutter blade to the normal position. There is a label near the cutter to assist you.
   

4. Close the cutter cover.

5. Open the roll paper cover and remove the jammed paper.

Cleaning

Cleaning the Printer Case

Be sure to turn off the printer, and wipe the dirt off the printer case with a dry cloth or a damp cloth.

CAUTION:
Never clean the product with alcohol, benzine, thinner, or other such solvents. Doing so may damage or break the parts made of plastic and rubber.

Cleaning the Thermal Head

CAUTION:
After printing, the thermal head and the frame on its side (indicated in the circle in illustration below) can be very hot. Be careful not to touch it and to let it cool before you clean it. Do not damage the thermal head by touching it with your fingers or any hard object.
Turn off the printer, open the roll paper cover, and clean the thermal elements of the thermal head with a cotton swab moistened with an alcohol solvent (ethanol or IPA).
Epson recommends cleaning the thermal head periodically (generally every 3 months) to maintain receipt print quality.

Setting the DIP Switches

CAUTION:
Be sure to turn off the printer before removing the cover of the DIP switches.
Removing it while the printer is turned on may cause problems such as an electric short, which leads to a malfunction of the printer.

1. Turn off the printer.
2. Turn over the printer.
3. Remove the DIP switch cover by removing the screw.
4. Set the DIP switches using a fine-tipped tool.
5. Replace the DIP switch cover, and fix it by installing the screw.
   The new setting becomes effective after the printer is turned on
