Canon MX330 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MX330 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MX330. 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.

Important Notes

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