Canon MB5450 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon MB5450 is common after many cleaning cycles. In most cases, a counter reset restores printing.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MB5450 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MB5450. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

• 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

Perform the Waste Ink Counter Reset

Completing the reset clears the internal ink absorber counter stored in printer memory and restores normal operation.

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.
