If your Canon IX6720 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

Ink absorber pads store waste ink during normal operation. Canon firmware tracks this using a software counter and may stop printing when it reaches the limit.

This page is prepared for Canon IX6720. 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

Once the counter is cleared, Canon IX6720 should exit the locked state and printing should resume normally.

Maintenance Reminder

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