Canon MAXIFY GX1020 Error 5B00: Ink Absorber Full Fix

The 5B00 error code on the Canon MAXIFY GX1020 signals that the internal ink absorber counter has reached its preset limit. This is a safety feature to prevent ink overflow from internal maintenance cleaning cycles. Resetting this requires entering service mode and updating the internal EEPROM, or replacing the physical absorber pad.

Common causes

  • 1Excessive use of automatic printhead cleaning functions.
  • 2Natural saturation of the internal waste ink pads over time.
  • 3High-volume document printing causing frequent maintenance cycles.
  • 4Internal counter firmware logic error following power instability.

Solutions

Diagnóstico rápido

The 5B00 error is characterized by an orange/amber light sequence and a 'Waste Ink Pad Full' message. The printer stops responding to all computer commands. If you see physical ink stains at the base of the machine, the overflow is already occurring.

Solución paso a paso

  1. Enter Service Mode: With the printer off, press and hold the 'Stop' button, then press and hold the 'Power' button.
  2. Initialization: Release the 'Stop' button while holding the 'Power' button, then press 'Stop' five times. Release both buttons.
  3. Use Reset Software: Run an approved Canon service tool from a computer connected via USB to reset the ink counter.
  4. Inspect/Replace: If applicable, verify the waste ink tank condition and replace it to avoid permanent hardware damage.

Prevención y mantenimiento

Limit the number of deep cleaning cycles. Every time you perform a cleaning, ink is dumped into the absorber. Keep the printer on a stable, level surface to ensure proper drainage. If you print at high volumes, plan for a professional pad replacement after roughly 15,000-20,000 pages.

Cuándo llamar a un técnico

If the reset fails or if ink is pooling inside the chassis, do not attempt to use the machine. In this state, professional service is required to prevent a short circuit in the printer's delicate logic board and print mechanisms.

Frequently asked questions

No, continuing to print risks ink leakage, which can cause severe electrical damage to your printer.

Reseting software will clear the error, but the physical ink remains. You should eventually replace the absorbent pads to avoid mess.
