If your Canon MX720 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

Inside Canon printers, absorber pads collect excess ink from cleaning and maintenance cycles. The printer uses an internal counter to estimate pad saturation.

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

What You May Notice

• 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

Reset the Ink Absorber Counter

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

Warnings

Treat the reset as a maintenance step. If your printer has extremely high usage, consider cleaning/replacing absorber pads to avoid overflow.

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

Common Fixes

• Try a different USB cable/port if using PC software.
• Use the correct Stop/Reset press count for your series.
• Repeat the service mode steps carefully (timing matters).
