Canon MX720 Ink Absorber Full Reset

When Canon MX720 triggers an ink absorber full condition, the printer may block printing as a protective measure. The solution is typically a waste ink counter reset.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MX720 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MX720. Service mode instructions are shown only when a matching series procedure is known.

Typical Signs

• 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

After service mode is enabled (if required), the waste ink counter can be reset using a supported reset procedure/software.

Before You Continue

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

Reset tools and instructions

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

Common Fixes

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