Solutions

Diagnóstico rápido

If your Epson WorkForce WF-2930 shows error W-03, identify on the screen if the unit specifies which of the colors (C, M, Y, K) is failing. This will allow you to clean only the relevant chip.

Solución paso a paso

  1. Access: Lift the scanner unit and wait for the carriage to move to the change position.
  2. Extraction: Remove the cartridge marked by the error.
  3. Cleaning: Wipe the gold contacts of the chip with a lint-free dry cloth.
  4. Reinstallation: Reinsert the cartridge firmly until the lock clicks.
  5. Verification: Close the unit and check if the screen recognizes the consumable.

Prevención y mantenimiento

To avoid error W-03, avoid touching the gold chips on the cartridges with your fingers, as natural skin oils can interfere with the signal. If you use third-party cartridges, be aware that Epson firmware updates can block their recognition automatically.

Cuándo llamar a un técnico

If after trying a new genuine cartridge the W-03 error persists in the same slot, the print carriage connector block might be damaged or leaking ink internally. In that case, professional technical support is required.
