Common causes

  • 1Excessive print head cleanings diverting ink to the waste reservoir.
  • 2High print volume exceeding the manufacturer's expected duty cycle.
  • 3Internal firmware lockout to prevent permanent mainboard damage.
  • 4Cumulative ink deposit from maintenance cycles over time.

Solutions

Diagnóstico rápido

The printer stops responding and displays 'Ink Absorber Full' or code 5B00. This happens after long-term use and many cleaning cycles. The printer will remain locked until this counter is manually reset via software.

Solución paso a paso

  1. Enter Service Mode: With the printer off, hold 'Stop', then press and hold 'Power'.
  2. Service Sequence: While holding 'Power', release 'Stop' and tap it 5 times. Release both buttons.
  3. Verify Connection: The LED should stop flashing, showing the printer is in Service Mode.
  4. Reset Counter: Connect via USB and use 'Service Tool' software to clear the 'Main' ink counter.

Prevención y mantenimiento

Reduce unnecessary cleaning cycles. Ensure the printer sits on a flat surface to allow ink to distribute evenly in the pads. Replace physical pads if you notice external ink leakage.

Cuándo llamar a un técnico

If you see physical ink pooling at the base of the printer or the error returns immediately after a reset, the pads are saturated and need mechanical replacement by a technician.
