Canon MX477 Ink Absorber Full Reset

If your Canon MX477 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 MX477. 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

Clear the Ink Absorber / Waste Ink Counter

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

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.

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

If It Doesn’t Work

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