Changing a Receipt Roll

CAUTION:Use roll paper that meets the printer specification. For details about paper specification, see the manufacturer's guide. Do not use a roll paper which is glued to the paper core.
  1. Press the cover open lever to open the roll paper cover.
  2. Remove the used paper roll core if there is one inside.
  3. Insert new paper roll as shown.
  4. Pull out some roll paper, and close the roll paper cover.


Testing the Printer

Check your printer with a self test.

Follow the steps:

  • Close the roll paper cover.
  • While pressing the feed button, turn on the printer. You'll need to hold down the feed button until printing starts.
  • After printing the current print status, a continuing self-test guidance is printed, and the power LED flashes.
  • Briefly press the feed button (less than one second) to continue the self-test.
  • After printing the self test, the printer initializes and switches to standard mode.

Cleaning the Printer

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.
  1. To remove the paper dust, clean the platen roller with a cotton swab moistened with water. Turn on the printer power only after the water has completely dried.
  2. Turn off the printer and open the roll paper cover. Clean the thermal elements of the thermal head with a cotton swab moistened with an alcohol solvent (ethanol or IPA).
    3. CAUTION:After printing, the thermal head can be very hot. Do not touch it and let it cool before you clean it. Do not damage the thermal head by touching it with your fingers or any hard object.

Paper Jam


If a foreign substance has entered the auto-cutter or the roll paper jams, the auto-cutter blade cannot return to the correct position and it locks in place. In this situation, the roll paper cover does not open even if you pull the cover open lever.
If the roll paper cover is jammed, follow these steps to return the auto-cutter blade to its normal position:
  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. Refer to the operation instructions engraved on the back of the cutter cover.
  4. Close the cutter cover.
  5. Open the roll paper cover and remove the jammed paper.
