Brother MFC-J1205W 'Cannot Detect' Error Fix

Solutions

Diagnóstico rápido

Confirm if the message identifies a specific color. If the error remains after opening and closing the cover, it's a communication issue between the cartridge chip and the main logic board.

Solución paso a paso

  1. Open the cartridge cover and remove the problematic ink cartridge.
  2. Inspect the metal chip for smudges or debris.
  3. Clean the contacts gently with a dry, lint-free cloth.
  4. Insert the cartridge firmly until it clicks into place and the locking lever engages.

Prevención y mantenimiento

Avoid touching the gold contacts on the cartridges. If you don't print often, run a self-test page monthly to keep the internal sensors and cartridge chips in active communication state.

Cuándo llamar a un técnico

If replacing the cartridge doesn't solve the issue, the internal sensor board that reads the chips might be failing, necessitating professional repair.
