If your Canon MB2020 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MB2020 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MB2020. Service mode instructions are shown only when a matching series procedure is known.

Common Symptoms

• ‘Ink Absorber Full’ / ‘Service Required’ message
• Support/service code (varies by series)
• Printing blocked after cleaning cycles
• Reset required to continue printing

Finalize the Reset and Restore Printing

Once the counter is cleared, Canon MB2020 should exit the locked state and printing should resume normally.

Before You Continue

If absorber pads are truly saturated, ignoring maintenance can lead to ink leakage inside the printer. The counter reset only removes the software lock.

Reset tools and instructions

For best results, avoid rushing button presses—consistent timing matters.

Common Fixes

• Repeat the service mode steps carefully (timing matters).
• Try a different USB cable/port if using PC software.
• Use the correct Stop/Reset press count for your series.
• Close other Canon printer utilities while resetting.
• Power-cycle the printer and try again.
