Solutions

Diagnóstico rápido

If the status lights blink and printing stops, the Epson TM-U220B POS paper error is the culprit. Check if the ink ribbon is loose or if the paper has wrinkles that catch on the roller.

Solución paso a paso

  1. Lift the top cover of the unit.
  2. Remove any paper scraps trapped in the mechanism carefully.
  3. Turn the side knob manually to align the paper correctly.
  4. Verify that the ERC-38 ribbon is not blocking the printhead.

Prevención y mantenimiento

Clean paper debris from inside the print chamber weekly. Use original ink ribbons to prevent the printhead from wearing out prematurely, which causes excessive friction during printing.

Cuándo llamar a un técnico

If the printhead makes strange squeaking noises when trying to print and the error persists, the internal gears might be damaged.
