Frequently Asked Questions - TM-L90 EPSON

How to install or replace the paper roll?

Open the paper roll cover by pulling the opening lever. Remove the used core, insert a new roll in the correct direction (the paper unwinds from the bottom), align the paper with the guides, then close the cover by pressing in the center. If the printer is powered on, the paper is automatically advanced and cut.

What to do if the error indicator is on or flashing?

Check that the roll cover is properly closed and that paper is present. If the paper indicator is on, the roll is empty or incorrectly placed. If the printer has been printing heavily, the thermal head may be hot: wait for it to cool. In case of a paper jam, open the cover and remove the jammed paper. If the problem persists, turn the printer off and then on.

How to clean the thermal print head?

Turn off the printer and disconnect the power cable. Open the paper roll cover. Wait for the thermal head to cool (it can be very hot after printing). Gently clean it with a cotton swab soaked in isopropyl alcohol. Avoid touching the head with fingers or hard objects. Let it dry completely before turning the printer back on.

How to perform a self-test?

Make sure paper is loaded and the cover is closed. Hold down the paper feed button while turning on the printer. Release the button when printing starts. The printer prints its settings, then the Paper indicator flashes. Press Feed to print a test pattern. The message '*** completed ***' confirms the end of the test.

How to connect the printer to an Ethernet network?

Connect an Ethernet cable to the Ethernet port on the back of the printer. Route the cable through the cable clamp to prevent disconnection. Close the protective cover. The printer supports 110BASE-T/100BASE-TX. For a wireless connection, use the OT-WL Series option on the USB port, but in that case, leave the Ethernet cable disconnected.

Printouts are dull or pale, what should I do?

The cause is likely glue or residue on the thermal head, the platen roller, or the paper path. First clean the thermal head with an alcohol-soaked cotton swab. If printing remains dull, also clean the platen roller and paper path. Always use the recommended paper type.

What paper widths are compatible?

The printer accepts rolls of 80 mm, 58 mm, and 40 mm width. A suitable paper guide must be installed: the default guide is for 58 mm. To use 80 mm, remove the guide. For 40 mm, remove the 58 mm guide and install the supplied 40 mm guide. Be careful not to install a guide in the wrong position.

What to do in case of a paper jam?

Turn off the printer. Open the paper roll cover. Carefully remove the jammed paper. Check that there is no glue or dirt on the paper cutter blade or platen roller. Clean if necessary. Properly replace the roll and close the cover. If the cover does not open, use a screwdriver to lift the side slots and turn the unlocking button with a pen.

How to turn the printer on/off and what to do if it does not turn on?

Use the power switch on the printer. After turning on, the printer is ready in about 30 seconds. If the power indicator does not light up, check that the power adapter is properly connected to the printer and to a wall outlet. Make sure the outlet is powered. Use only the supplied adapter.

What are the important safety precautions?

Do not use the printer in the presence of flammable vapors. Disconnect immediately if there is smoke, odor, or abnormal noise. Do not open the cover during printing. The thermal head is hot after use, let it cool before touching. Do not disassemble or repair the device yourself. Use only Epson-approved accessories and consumables.

Cleaning

Cleaning the Printer Case

When cleaning the printer case, be sure to turn off the printer, and wipe the dirt off the printer case with a dry or 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 Inside the Printer

When print quality is deteriorated, clean the paper path (such as the autocutter blade, platen roller, thermal head, and the roll paper holder).

To clean these parts, turn off the printer, unplug the AC cable, open the roll paper cover, and remove the paper dust, adherent glue, or other foreign substance with a cotton swab or cloth moistened with an alcohol solvent (ethanol or IPA).

If paper dust adheres around the black mark sensor, blow or wipe it off to keep the operation of the printer normal.

For the locations of each part, see the illustration.

CAUTION:

☐ If adherent glue is attached, be sure to wipe it all off.
☐ Take care not to injure your fingers on the manual cutter when cleaning.
☐ Before turning on the printer after cleaning, allow alcohol on the printer to dry completely.

CAUTION:

The thermal head can be very hot after printing. 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.

Wipe off all glue on these edge and ribs. Blow or wipe off the paper dust around the black mark sensor. Paper path Autocutter blade Platen roller Wipe off all glue in the touchable area of the autocutter and the platen roller.

Running a Self-test

In self-test mode the printer will perform a series of internal diagnostics, and then provide a listing of printer settings.

Having a printed self-test in hand when calling for technical support can help speed the troubleshooting process.

Use the following procedure to start a self-test.

1. Close the roll paper cover.
2. While pressing the Feed button on the control panel, turn on the printer. (Keep pressing the Feed button until the printer starts printing.)
   The printer prints out the various printer states.
3. When all printer states have been printed, make sure that the following message is displayed and the Paper LED flashes.
   "If you want to continue SELF-TEST printing, please press Feed button."
   The printer is now in the self test wait mode.
4. To start a test print, press the Feed button when the printer is in the self test wait mode.
5. Check that the following has been printed.
   "*** completed ***"
   This indicates that the printer has been initialized and made the transition to the normal mode.

Resetting the Printer

Certain error conditions can be reset by turning the printer off then back on.

Not all error conditions can be reset using this method. (☐ "Troubleshooting" on page 18)

Troubleshooting

Power LED does not light

Check whether the AC adapter is correctly connected. (☐ "Connecting the AC Adapter" on page 11)

Error LED on or flashing

☐ Check to see that the roll paper cover is closed and check the Paper LED. Close the cover or replace the roll paper if necessary.
☐ If the Paper LED is on, check whether the roll paper is correctly installed and any roll paper remains. (☐ "Installing or Replacing the Roll Paper" on page 14)
☐ If the printer has been printing a lot, the thermal head may be hot. Wait for the head to cool. Printing will resume automatically.
Open the roll paper cover, and check to see if the paper is jammed. If a paper jam occurs or if the roll paper cover will not open, see the section below.
☐ Turn the printer off and back on. If the LED is still flashing, notify your manager. The printer may require servicing.

Printout is faint

When printout is faint, adhesive glue or another foreign substance may be present on the thermal head, platen roller, or paper path of the printer.

In such case, first clean the thermal head by following the instructions described in "Cleaning Inside the Printer" on page 15.

If the print quality does not improve, clean the platen roller and paper path of the printer by following the instructions described in "Cleaning Inside the Printer" on page 15.

Printed character size is not appropriate for 40 mm/58 mm width paper

When using 40 mm/58 mm width roll paper, if the printed character size is not appropriate or if the printout does not fit within the paper width, the paper guide may not be installed correctly. ( "Installing the Paper Guide" on page 8)

Paper jam

Turn off the power and open the roll paper cover to remove the jammed paper. After that, install the roll paper correctly. If the roll paper cover will not open, see the section below.

If glue or another foreign substance is present on the autocutter blade, platen roller, or the paper path, a paper jam is likely to occur. (☐ "Cleaning Inside the Printer" on page 15)

The roll paper cover will not open

Follow the steps below when the roll paper cover will not open.

1. Turn off the printer.
2. Insert a tool such as a screwdriver into the slots on both sides of the printer, and lift the cover in the direction of the arrow to remove it.
