When using the printer, make sure the protective cover indicated in the illustration below fits firmly into place.

When LAN cables are installed outdoors, make sure devices without proper surge protection are cushioned by being connected through devices that do have surge protection. Otherwise, the devices can be damaged by lightning.

Note:
Connecting the optional Wireless LAN Cable Set (OT-WL01) to the USB connector enables the wireless LAN connection. While connecting via wireless LAN, keep the Ethernet cable unconnected to the printer.

Connect each cables to the connectors at the back of the printer. See the illustration below for the positions of the connectors.

Note: Connectors marked “❋“ above are not available currently.
Connect other ends of the cables to external devices.

Attaching the Connector Cover

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

Note:
The connector cover has 3 cable exits in different directions. When pulling out the cables whose connector does not lock itself (USB cable and DC 5 V cable) from the cable exits on the back, fix the cables with the cable band to prevent the cables from coming off. ( See illustration B on page ii.)

Turn over the printer.
Position the two hooks on both sides of the connector cover so that they hook the printer case, as shown in illustration D.
Push the connector cover to click onto the printer case, as shown in illustration D.
Pass each cable through the cable exits at the bottom of the connector cover.
If the cables are too many for one cable exit, use multiple exits.
Turn over the printer, and make sure the cables are not pinched. ( See illustration C.)

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. See illustration **E.

Press the cover open button to open the roll paper cover. (See illustration F.)
Remove the used roll paper core if any, and insert the roll paper in the correct direction. See illustration G on page iii.
Pull out some paper, and close the roll paper cover, as shown in illustration H.
Tear off the paper, as shown in illustration **I.

Changing the Paper Width

If a roll paper guide is included with your printer, you can change the printer 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

Press the cover open button to open the roll paper cover. (See illustration F.)
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, as shown in illustration J.
Tighten the enclosed screw to fix the roll paper guide.
Affix the enclosed 2 strips along the roll paper guide on the bottom of the roll paper holder, as shown in illustration K.

Make sure the space between the top edge of strips and the line of the groove in the roll paper guide (indicated as a in the illustration) is 0.5 mm or less.
Install the roll paper correctly.
Close the roll paper cover.

Test Printing

After the printer setup or when the printer is not operating correctly, you can check the printer operation with test printing. If the printer performs pattern printing when you follow the steps below, the printer is operating normally.

Make sure the paper is correctly inserted and all the covers are closed.
While pressing the Feed button, turn on the printer.
After the printer prints its status and the Paper LED flashes, press the Feed button again to restart the test printing.

The test printing is completed when “ completed” is printed.

Attaching the Power Switch Cover

The enclosed power switch cover ensures that the power switch is not pressed accidentally. You can turn the power switch on and off by inserting a sharppointed object in the holes in the power switch cover. To remove the cover, use a sharp-pointed object.
To use this cover, install it as shown in illustration L on page iv.

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

About Network Connection

Confirming the Network Settings
Make sure the printer is turned on, press the push button at the interface part (shown in the following illustration) for approximately 3 seconds. When you release the button, a status sheet on which network parameters are printed will be ejected.
With the status sheet, you can check all the settings necessary for connecting to the network.

Note:
If you keep pressing the button for more than 10 seconds, the network settings are initialized. (See “Initializing the Network Setting” on page 8.)
The printer is initially set so that the IP address for the wired LAN will be obtained by DHCP. When you turn on the printer, the IP address is obtained and then it will be printed out automatically.

Network Setting
Make the same settings on the computer and access points as those printed in the status sheet.
Use the web browser to make the network settings. Input the printer’s IP address in an address bar of the web browser, and make the network settings as directed in TM-T88V-i Technical Reference Guide

Initializing the Network Setting
To reset the network settings to the default values, press the push button at the interface part (shown in the following illustration) for more than 10 seconds.
When you release the button, the initialization will be started.

Troubleshooting

No lights on the control panel
Check whether the printer is correctly connected to a power source. (See “Connecting to a Power Source” on page 5.)

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.

No connection to external devices

When the status LED (shown in the illustration on page 8) is lit in green

Check whether the interface cable or the wireless LAN cable set (optional product) is connected correctly. (See “Connecting to External Devices” on page 5.)
Print the status sheet to check whether the network settings are correct. (See “Confirming the Network Settings” on page 8.)

When the status LED (shown in the illustration on page 8) is off / lit in orange
When the status LED is off after turning on the printer or remains lit in orange even if 30 seconds have passed after turning on the printer, the interface board needs repairing

Paper is jammed

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 illustration O) because it can be very hot after printing.

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

Turn off the printer.
Slide the cutter cover toward the front to open it, as shown in illustration M.
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. See illustration N.
Close the cutter cover.
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 O) 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). See illustration O.

Epson recommends cleaning the thermal head periodically (generally every 3 months) to maintain receipt print quality.
