Diagnóstico rápido

Error 18-005 occurs when the chip reader in the printer does not receive a valid signal from the toner chip. If you have recently replaced the toner, ensure the protective packaging is fully removed. This error is specific to communication and usually does not mean the cartridge is empty.

Solución paso a paso

  1. Remove: Take the cartridge out and inspect the gold contacts.
  2. Clean: Wipe the contacts gently with a clean, dry microfiber cloth.
  3. Inspect: Ensure no debris is inside the cartridge housing.
  4. Reset: Reinsert firmly and close the door; the machine will automatically try to re-detect.

Prevención y mantenimiento

Always handle toner cartridges by the edges. Avoid contact with the electrical chip. If the error continues, try swapping in another cartridge to rule out a defective chip on the current unit.

Cuándo llamar a un técnico
