Solutions

Diagnóstico rápido

If the error appears immediately after changing the toner, it is likely the cartridge was not seated deeply enough or the chip contacts have residue on them.

Solución paso a paso

  1. Open the front door and pull out the drum/toner unit.
  2. Extract the toner cartridge and push it back in firmly until you hear a 'click'.
  3. Gently wipe the golden chip on the toner with a lint-free cloth.
  4. Power off and on the printer to allow the system to re-scan consumables.

Prevención y mantenimiento

Avoid touching the gold pins on the chip with bare hands (natural skin oils affect connectivity). Keep the interior of the printer free of toner dust.

Cuándo llamar a un técnico

If the 30-104 error persists after testing two different cartridges, the internal contact sensor within the printer may have been displaced or damaged.

Frequently asked questions

This error indicates that the toner chip cannot communicate with the printer, either due to poor insertion, dirt, or a faulty chip.

The manufacturer recommends using original TL-5120 series toners to avoid chip compatibility issues and maintain the machine's warranty.

If you have tested with a new original toner and the error continues, the printer's internal contact sensor might be dirty or broken.

Store cartridges in their original packaging, in a cool and dark place, and avoid touching the metallic chips.
