If your Canon MP550 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 MP550 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MP550. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

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

Perform the Waste Ink Counter Reset

Once the counter is cleared, Canon MP550 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.

If your model does not show a service mode section, it means no matching procedure was found for its series.
