If your Canon MB5000 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 MB5000 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MB5000. Service mode instructions are shown only when a matching series procedure is known.

Common Symptoms

• Service / maintenance warning on the screen or driver
• Printer refuses to print even with ink available
• Blinking lights and queued jobs fail
• Error reappears after restart

Clear the Ink Absorber / Waste Ink Counter

Once the counter is cleared, Canon MB5000 should exit the locked state and printing should resume normally.

Maintenance Reminder

Resetting the counter does not physically clean the absorber pads. For heavy usage, pads may eventually need cleaning or replacement.
