Solutions

Diagnóstico rápido

If you see error 0x69, the printer is likely indicating that the waste ink counter is at maximum capacity. Check if the maintenance box unit is correctly seated or if the chip contacts are dirty.

Solución paso a paso

  1. Locate the maintenance box panel on the back of the printer.
  2. Remove the box and inspect the gold contacts on the chip for any moisture or corrosion.
  3. Clean the electrical pins with a pencil eraser or alcohol cloth to ensure a perfect connection.
  4. Update the printer firmware via the official Epson website to refresh the system's ability to read component status.

Prevención y mantenimiento

Only use genuine Epson maintenance boxes. Avoid running repetitive, unnecessary nozzle cleanings, as these shorten the lifespan of the maintenance box by filling it up with waste ink prematurely.

Cuándo llamar a un técnico

If replacing the maintenance unit and cleaning the contacts doesn't resolve the 0x69 code, there may be a deeper issue with the mainboard that requires professional diagnostic service.
