Solutions

Diagnóstico rápido

The 5B00 error is a pre-programmed maintenance warning. Do not attempt to bypass this error by forcing prints, as it may cause internal ink leakage that can permanently damage the printer's mainboard.

Solución paso a paso

  1. Purchase the MC-G02 maintenance cartridge, required for secure residual ink handling.
  2. Open the maintenance compartment door located at the rear/side of the unit.
  3. Carefully slide out the used cartridge to avoid ink stains.
  4. Insert the new cartridge until it clicks securely into position.
  5. Reset the counter via the printer's service menu if not detected automatically.

Prevención y mantenimiento

Avoid performing deep cleaning cycles unless print quality issues make it strictly necessary, as these consume the maintenance cartridge life rapidly. Keep the printer on a perfectly level surface to ensure residual ink distributes evenly.
