Important Notes on Installation

  • For a serial interface, you must use a null modem cable, also called a cross cable.
  • For a parallel interface, use a cable that meets the specifications for an IEEE 1284-compliant cable.
  • For a USB interface, install the printer driver before connecting the printer.

Installing the Printer

You can install this printer only horizontally.

Fix the printer so that it does not move around when you open the printer cover and cut roll paper. A tape for fixing the printer is available as an option.

As shown in the illustration C, install the printer with a maximum tilt of 3°.

Installing the printer with a tilt of more than 3° may cause the following problems.

  • Roll paper near end cannot be detected.
  • The printer cover will not close after installing roll paper.
  • Roll paper cannot be taken out.

Using the Power Switch Cover


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

The enclosed power switch cover ensures that the power switch is not pressed accidentally. To use this cover, install it as shown in illustration D.

Installing Roll Paper

  1. Press the lever indicated by the arrow in illustration E to open the printer cover.
  2. Remove the used roll paper core.
  3. Install the roll paper as shown in illustration F. The correct direction of the paper is shown in illustration G.
    Installing Roll Paper
    7-Paper guides
  4. Pull out some roll paper as shown in illustration H so that the paper is set between the paper guides.
  5. Close the printer as shown in illustration I, and make sure that the roll paper is properly installed between the paper guides.
  6. Tear off the roll paper as shown in illustration J.

Troubleshooting

No lights on the control panel

Check if the power supply cable is correctly connected to the printer and the power outlet.

ERROR LED on (not flashing) with no printing

If PAPER OUT is on, the roll paper is not installed or is used up.

If PAPER OUT is off, the printer cover is not closed properly.

ERROR LED flashing with no printing (and no paper jam)

Printing stops if the thermal head overheats and resumes automatically when it cools.

If overheating is not the cause, turn the printer off, and after 10 seconds, back on.

Removing Jammed Paper

cautionburn hazardCAUTION:
Do not touch the thermal head because it can be very hot after printing.

  1. Turn the printer off and press the cover open lever.
  2. Remove jammed paper, reinstall the roll, and close the printer cover.

Cleaning the Thermal Head

cautionburn hazardCAUTION:
After printing, the thermal head can be very hot. Do not 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 and open the printer cover. As shown in illustration K, clean the thermal elements of the thermal head with a cotton swab moistened with an alcohol solvent (ethanol, or IPA).
Cleaning the Thermal Head

  1. Thermal head

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

Setting the DIP Switches


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. Make sure the printer is turned off.
  2. Turn over the printer.
  3. As shown in illustration L, remove the cover of the DIP switches on the printer bottom by removing a screw.
  4. Set the DIP switches using a fine-tipped tool.
  5. Replace the cover of the DIP switches, and fix it by installing the screw.

The new setting becomes effective after the printer is turned on.
